Spina Bifida (LA02): Complete ICD-11 Coding Guide

1. Introduction

Spina bifida represents the most frequently observed neural tube defect in clinical practice, constituting a complex congenital malformation that affects the vertebral column and, in various cases, the spinal cord. This defect results from incomplete closure of the neural tube during the first weeks of embryonic development, specifically between the 17th and 30th day of gestation, a period when many pregnant women are still unaware of their pregnancy.

The condition manifests itself across a spectrum of variable severity, ranging from occult forms that are practically asymptomatic to severe presentations with significant neurological compromise. Open spina bifida, characterized by incomplete dorsal closure of the vertebrae, can result in the formation of a sac containing meninges (meningocele) or spinal cord and meninges (myelomeningocele), the latter representing the most severe and common form of the condition.

The clinical importance of spina bifida transcends the initial anatomical defect, as its consequences include paraplegia of the lower limbs, hydrocephalus, Chiari malformation, urinary and anorectal incontinence, in addition to other complications that significantly impact patients' quality of life. The intensity of these signs varies substantially according to the vertebral level and the extent of the lesion.

Adequate coding of this condition is critical for health resource planning, epidemiological monitoring, scientific research, and ensuring access to the necessary multidisciplinary treatments. The transition to ICD-11 brought greater specificity in the classification of neural tube defects, allowing for more precise documentation and facilitating international comparative studies.

2. Correct ICD-11 Code

Code: LA02

Description: Spina bifida

Parent category: null - Anomalies of structural development of the nervous system

Official definition: Spina bifida is the most common of a group of congenital defects called neural tube defects. Spina bifida affects the spine and sometimes the spinal cord. Open spina bifida defines the failure of dorsal closure of the vertebrae, associated with varying degrees of spinal column defects. A pouch of skin may form, containing meninges (meningocele) or spinal cord and meninges (myelomeningocele). Different subtypes are found according to the location of the defect. The consequences are paraplegia (paralysis of the lower limbs), hydrocephalus, Chiari malformation (resulting from spinal cord tethering during intrauterine life), urinary and anorectal incontinence. The intensity of signs varies greatly with the level and extent of the lesion.

This main code has subcategories that allow specification of the anatomical location of the defect, providing greater diagnostic precision and facilitating therapeutic planning. The ICD-11 classification recognizes that spina bifida is not a single entity, but a spectrum of malformations with different clinical and prognostic implications.

3. When to Use This Code

The code LA02 should be used in specific clinical situations where there is diagnostic confirmation of spina bifida. The following detailed practical scenarios are presented:

Scenario 1: Newborn with lumbar myelomeningocele A neonate presents at birth with a cystic mass in the lower lumbar region, with a palpable bone defect in the vertebral column. Physical examination reveals absence of movement in the lower limbs, absence of patellar and Achilles reflexes, and urinary incontinence. Cranial ultrasonography demonstrates ventriculomegaly. This case represents a classic presentation of open spina bifida of the myelomeningocele type, justifying the use of code LA02 with specification of location.

Scenario 2: Confirmed prenatal diagnosis During second trimester morphological ultrasonography, a defect in fetal vertebral column closure is identified in the thoracolumbar region, with protrusion of contents through the bone defect. Fetal magnetic resonance imaging confirms myelomeningocele with signs of Chiari type II malformation. In this context, code LA02 is appropriate for documentation of prenatal diagnosis, allowing adequate planning of delivery and immediate postnatal interventions.

Scenario 3: Sacral meningocele in an infant A three-month-old child presents with a cystic tumor covered by skin in the sacral region, identified since birth but without apparent neurological signs. Magnetic resonance imaging confirms sacral bone defect with herniation of meninges only, without neural tissue involvement. Despite the less severe presentation, this is spina bifida of the meningocele type, coded as LA02 with appropriate specification.

Scenario 4: Child with sequelae of corrected spina bifida A five-year-old patient with a history of surgical correction of lumbosacral myelomeningocele in the neonatal period, currently under multidisciplinary follow-up for paraplegia, neurogenic bladder, and ventriculoperitoneal shunt for hydrocephalus. Code LA02 remains relevant for documenting the underlying condition, even after surgical correction, as neurological sequelae persist.

Scenario 5: Adolescent with symptomatic occult spina bifida A 14-year-old patient with a history of progressive urinary changes and foot deformity. Investigation by magnetic resonance imaging reveals a defect in posterior closure of lumbar vertebrae with intraspinal lipoma and tethered spinal cord. This late presentation of occult spina bifida, when symptomatic and with documented vertebral defect, justifies the use of code LA02.

Scenario 6: Evaluation of young adult for family planning A 25-year-old adult with an established diagnosis of spina bifida since birth, currently in a wheelchair, seeks genetic counseling. Code LA02 is used to document the existing condition during the medical genetics consultation, allowing appropriate epidemiological recording and family counseling.

4. When NOT to Use This Code

There are specific situations where code LA02 should not be applied, requiring the use of more appropriate alternative codes:

Arnold-Chiari malformation type I (code 1383121646): When the patient presents with descent of cerebellar tonsils through the foramen magnum without association with spina bifida or neural tube defect. This condition frequently manifests in adulthood with headache, cerebellar alterations, and syringomyelia, but without vertebral defect. Differentiation is fundamental, as Chiari type I is a malformation of the craniocervical junction, not a neural tube defect.

Arnold-Chiari malformation type II (code 1987349422): Although Chiari type II malformation is frequently associated with spina bifida, when the primary clinical focus and reason for care is specifically the Chiari malformation with its complications (such as hydrocephalus from fourth ventricle obstruction), the specific code for Chiari type II should be prioritized. However, LA02 may be used as an additional code to document coexisting spina bifida.

Occult spinal dysraphism (code 449489594): Conditions such as intraspinal lipoma, diastematomyelia, dermal sinus, or other forms of occult spinal dysraphism without evident posterior bony defect should not be coded as LA02. These conditions represent failures in neural tube closure of a different nature, usually covered by normal skin and without formation of meningeal or myelomeningeal sac.

Isolated vertebral column defects: Isolated vertebral anomalies such as hemivertebrae, block vertebrae, or other bony malformations without meningeal or spinal cord involvement do not constitute spina bifida and require specific codes for bony malformations.

Traumatic or acquired spinal cord lesions: Vertebral fractures, traumatic spinal cord injuries, or degenerative processes resulting in exposure of the vertebral canal are not spina bifida, as this is a congenital condition. These situations require codes for trauma or acquired diseases.

Isolated asymptomatic occult spina bifida: The presence only on imaging of posterior arch fusion defect of S1, without any clinical manifestation, associated lipoma, or neurological alteration, generally does not require active coding, being considered a common anatomical variant.

5. Step-by-Step Coding Process

Step 1: Assess diagnostic criteria

Diagnostic confirmation of spina bifida requires systematic evaluation that combines clinical and imaging elements. In the neonatal period, physical examination reveals the presence of a visible or palpable defect in the dorsal midline, with or without a cystic sac. Careful inspection identifies the affected vertebral level, the presence of intact or ulcerated skin over the lesion, and signs of cerebrospinal fluid leakage.

Neurological evaluation documents the functional level through motor examination of the lower limbs, deep tendon reflexes, anal sphincter tone, and presence of spontaneous movements. Specific tests such as the bulbocavernosus reflex aid in assessing sacral spinal cord function.

Imaging studies are fundamental: plain radiographs of the spine demonstrate the bone defect and its level; ultrasound can be used in neonates before fontanelle closure; magnetic resonance imaging is the gold standard, revealing detailed anatomy of the defect, sac contents, level of spinal cord lesion, presence of hydrocephalus, and associated Chiari malformation.

Prenatal ultrasound allows early diagnosis, identifying the posterior bone defect, content protrusion, and indirect signs such as abnormal skull shape (lemon sign) and cerebellum (banana sign).

Step 2: Verify specifiers

Spina bifida presents different subtypes that must be specified for precise coding. Primary classification distinguishes between occult spina bifida (covered by skin) and open spina bifida (without complete cutaneous coverage).

In open spina bifida, meningocele (sac containing only meninges and cerebrospinal fluid, without neural tissue) and myelomeningocele (sac containing spinal cord and/or nerve roots in addition to meninges) are differentiated. Myelomeningocele represents the most severe and common form.

Anatomical location is crucial: cervical, thoracic, lumbar, lumbosacral, or sacral. The specific vertebral level determines functional prognosis, as higher lesions generally result in greater neurological impairment.

Severity is assessed by the extent of neurological deficit, presence of complications such as hydrocephalus, Chiari malformation type II, and need for ventricular shunt. Documenting whether surgical correction was performed and current functional status is essential for longitudinal follow-up.

Step 3: Differentiate from other codes

LA00 - Anencephaly and similar malformations: The fundamental difference is that anencephaly involves absence of skull and brain development, with failure of neural tube closure at the cranial end, whereas spina bifida affects the vertebral column. Anencephaly is incompatible with life, unlike spina bifida. Clinically, anencephaly presents with absence of the cranial vault and brain tissue, easily distinguished from the dorsal protrusion of spina bifida.

LA01 - Cephalocele: This condition involves herniation of cranial contents (meninges and/or brain tissue) through a skull defect, typically occipital, frontal, or parietal. The differentiation is anatomically clear: cephalocele affects the skull with cranial protrusion, whereas spina bifida affects the vertebral column with dorsal protrusion. There is no anatomical overlap between these conditions, although both are neural tube defects.

LA03 - Arnold-Chiari malformation type II: This malformation frequently coexists with spina bifida, especially myelomeningocele, characterized by descent of the cerebellum, fourth ventricle, and brainstem through the foramen magnum. When the clinical presentation and focus of care are the complications of Chiari malformation (such as apnea, dysphagia, tetraparesis), code LA03 should be prioritized. However, when the spinal defect is the primary focus, LA02 is appropriate, with LA03 potentially added as a secondary diagnosis.

Step 4: Required documentation

Adequate documentation to justify code LA02 must include:

Checklist of mandatory information:

Detailed description of the defect: precise vertebral location, longitudinal extent
Type of spina bifida: meningocele, myelomeningocele, or occult
Presence or absence of cutaneous coverage
Complete neurological evaluation: motor level, sensory, reflexes
Bladder and bowel function: continence, need for catheterization
Presence of hydrocephalus and treatment (shunt or not)
Associated Chiari malformation and type
Orthopedic deformities: clubfoot, hip dislocation, scoliosis
Surgical interventions performed: defect correction, ventricular shunt
Current functional status: ambulation, use of orthoses, wheelchair
Imaging studies with detailed reports

The medical record must allow traceability of diagnosis from the neonatal or prenatal period, documenting clinical evolution and interventions performed over time.

6. Complete Practical Example

Clinical Case

Female newborn born via cesarean delivery at 37 weeks of gestation following prenatal diagnosis of myelomeningocele. The pregnancy was monitored regularly, with second trimester morphological ultrasound identifying a defect in vertebral column closure in the lumbosacral region, cystic protrusion, and signs of cerebral ventriculomegaly. Fetal magnetic resonance imaging confirmed L4-S2 myelomeningocele with Chiari type II malformation.

At birth, the neonate presented with adequate weight (2,950g) and good vitality (Apgar 8/9), but exhibited a cystic mass approximately 5cm in diameter in the lower lumbosacral region, partially covered by a translucent membrane, with a central ulcerated area showing clear fluid leakage. The bony defect was palpable, extending approximately four vertebral levels.

Neurological examination revealed normal spontaneous movements of the upper extremities, limited movements of the thighs with preserved flexion and adduction, but complete absence of leg and foot movements bilaterally. Patellar reflexes were absent bilaterally, as were Achilles reflexes. Anal sphincter tone was diminished, and there was no response to the cutaneous anal reflex. The lower extremities presented with bilateral equinovarus deformity.

Transfontanelar ultrasound performed in the first hours of life demonstrated moderate ventriculomegaly with ventricular index above the 97th percentile for gestational age, confirming hydrocephalus. Postnatal magnetic resonance imaging detailed the anatomy of the lesion: complete posterior defect from L4 to S2, with protrusion of distal spinal cord and nerve roots through the defect, forming an exposed neural placode. Descent of the cerebellar tonsils and vermis through the foramen magnum was confirmed, characterizing Chiari type II malformation.

Step-by-Step Coding

Analysis of diagnostic criteria: The patient presents all criteria for spina bifida: congenital defect of neural tube closure, confirmed by pre- and postnatal imaging; documented posterior bony defect from L4 to S2; protrusion of neural and meningeal contents through the defect (myelomeningocele); direct neurological consequences including paraplegia of the lower extremities, urinary and anorectal incontinence; associated hydrocephalus; coexisting Chiari type II malformation.

Primary code selected: LA02 - Spina bifida

Complete justification: Code LA02 is appropriate because the primary condition is myelomeningocele type spina bifida, representing the most severe and common neural tube defect. The clinical presentation is typical, with a visible defect at birth, lumbosacral location (most frequent), involvement of neural tissue (differentiating from simple meningocele), and neurological consequences proportional to the lesion level. The diagnosis was confirmed by multiple imaging methods and detailed clinical examination.

The selection of LA02 as the primary code, rather than the specific code for Chiari type II malformation, is justified because the spinal defect is the primary pathology, and Chiari malformation is a known consequence of spina bifida. The focus of immediate treatment will be surgical correction of the spinal defect within the first 48-72 hours of life, followed by management of hydrocephalus.

Applicable complementary codes:

LA03 (Arnold-Chiari type II malformation) - as a secondary diagnosis, documenting the associated malformation
Specific code for congenital hydrocephalus - documenting this complication that may require ventricular shunting
Codes for orthopedic deformities (bilateral equinovarus feet) - documenting musculoskeletal complications
Code for neurogenic bladder - documenting vesical dysfunction that will require specific management

This multiple coding approach allows complete documentation of coexisting conditions, facilitating resource planning, multidisciplinary follow-up, and appropriate epidemiological analysis.

7. Related Codes and Differentiation

Within the Same Category

LA00 - Anencephaly and similar malformations

When to use LA00: This code is applied when there is absence of brain development and cranial vault, resulting from failure of neural tube closure at the cranial end. The condition is diagnosed prenatally by ultrasound showing absence of brain structures above the base of the skull, or at birth by obvious absence of skull and brain.

When to use LA02: Used when the neural tube defect affects the vertebral column, with or without protrusion of meningeal or neural content, but with preserved cranial and brain structures.

Main difference: The distinction is anatomically clear - anencephaly affects the cranial pole of the neural tube with absence of brain development, while spina bifida affects the caudal pole with vertebral defect. Anencephaly is incompatible with prolonged survival, while spina bifida allows survival with appropriate treatment.

LA01 - Cephalocele

When to use LA01: Applicable when there is herniation of intracranial content (meninges, cerebrospinal fluid and/or brain tissue) through a skull defect, manifesting as a cystic mass in the occipital, frontal, parietal region or at the base of the skull. Diagnosis is confirmed by physical examination identifying cranial mass and imaging demonstrating cranial bone defect with content herniation.

When to use LA02: When the defect involves the vertebral column with herniation through a posterior bone defect, located on the dorsum of the trunk, not on the head.

Main difference: The anatomical location is completely distinct. Cephalocele presents as a mass on the head with cranial defect, while spina bifida manifests as a dorsal defect in the midline of the trunk. There is no anatomical ambiguity between these conditions.

LA03 - Arnold-Chiari malformation type II

When to use LA03: This code is prioritized when the main clinical focus is the manifestations of Chiari type II malformation, such as central apnea, laryngeal stridor, dysphagia, upper limb weakness, or complications of brainstem compression, even in the presence of coexisting spina bifida.

When to use LA02: When the spinal defect is the main presentation and the focus of care, such as in the immediate neonatal period when surgical correction of the defect is prioritized, or in follow-up focused on sequelae of paraplegia and vesicointestinal dysfunction.

Main difference: Although they frequently coexist (approximately 90% of myelomeningoceles have associated Chiari type II), the distinction is based on clinical focus. LA02 emphasizes the spinal defect and its direct consequences (paraplegia, incontinence), while LA03 emphasizes the craniocervical junction malformation and its consequences (brainstem dysfunction). Frequently, both codes are used together, with prioritization based on clinical context.

Differential Diagnoses

Occult spinal dysraphism: Conditions such as intraspinal lipoma, diastematomielia, or dermal sinus may present with subtle neurological signs or cutaneous alterations in the midline (hyperpigmented patches, hair tufts, dimples), but differ from open spina bifida by the absence of evident posterior bone defect and absence of meningeal or myelomeningeal sac. Magnetic resonance imaging investigation differentiates these conditions.

Ruptured myelomeningocele: Although technically a spina bifida, when there is complete rupture of the sac with total exposure of the neural placode from birth, the presentation may be confused with other lesions. The history of defect present since birth and confirmation by imaging establish the correct diagnosis.

Sacrococcygeal masses: Sacrococcygeal teratomas or other masses in the sacral region may be confused with meningocele, but the absence of vertebral bone defect on imaging and the presence of heterogeneous solid components instead of a simple cyst allow differentiation.

8. Differences with ICD-10

In ICD-10, spina bifida was coded in category Q05, with subdivisions based primarily on anatomical location: Q05.0 (cervical), Q05.1 (thoracic), Q05.2 (lumbar), Q05.3 (lumbosacral), Q05.4 (unspecified), Q05.5 (occulta), Q05.6 (with hydrocephalus), Q05.7 (without hydrocephalus), Q05.8 (other), and Q05.9 (not specified).

The transition to ICD-11 with code LA02 brought significant changes in the classification approach. The hierarchical structure was reorganized, with LA02 serving as the main code and subcategories allowing more detailed specification. ICD-11 emphasizes classification based on clinical characteristics beyond simple anatomical location.

An important change is the clearer separation between spina bifida and its associated complications. In ICD-10, the presence or absence of hydrocephalus was incorporated into the spina bifida code (Q05.6 vs Q05.7). In ICD-11, hydrocephalus can be coded separately, allowing more precise documentation of multiple coexisting conditions.

Chiari malformation type II, frequently associated with myelomeningocele, receives a specific code in ICD-11 (LA03), whereas in ICD-10 it could be implicitly included in the spina bifida code or require additional coding in another category.

The practical impact of these changes includes greater precision in clinical documentation, allowing for more detailed epidemiological analyses. The possibility of multiple coding facilitates the monitoring of specific complications and health resource planning. For researchers, the new structure enables more robust comparative studies between different populations and health systems.

Healthcare professionals should be attentive during the transition period, ensuring that hospital information systems are updated appropriately. Clinical documentation should be sufficiently detailed to allow precise coding in the new system, specifying not only the presence of spina bifida, but also its location, type, and associated complications.

9. Frequently Asked Questions

1. How is spina bifida diagnosed?

Diagnosis can occur at different times. During pregnancy, second trimester morphological ultrasound (performed between 18-24 weeks) identifies defects in fetal spinal column closure, visualizing the bone defect and protrusion of contents. Indirect signs include alterations in skull shape (lemon sign) and cerebellum (banana sign). Elevated levels of alpha-fetoprotein in maternal blood or amniotic fluid suggest neural tube defect, although they are not specific. Fetal magnetic resonance imaging provides superior anatomical detail when diagnostic doubts exist. At birth, diagnosis is evident by the presence of a visible or palpable defect in the dorsal midline, with or without a cystic sac. Postnatal imaging studies (radiography, ultrasound in neonates, or magnetic resonance imaging) confirm the diagnosis, detail the anatomy of the defect, and identify associated complications such as hydrocephalus and Chiari malformation.

2. Is treatment available in public health systems?

Spina bifida requires a complex and prolonged multidisciplinary approach. Initial surgical treatment for defect closure is considered an essential procedure and is available in pediatric neurosurgery referral centers in most public health systems. Surgery should preferably be performed within the first 48-72 hours of life to minimize risks of infection and additional neurological damage. Complementary treatments include ventricular shunt for hydrocephalus, physical therapy, occupational therapy, urological follow-up with intermittent catheterization, orthopedic follow-up for deformities, and psychosocial support. The availability and accessibility of these services vary significantly among different regions and health systems, but the global trend is to recognize spina bifida as a priority condition requiring comprehensive coverage. Orthoses, wheelchairs, and adaptive equipment may have more limited availability depending on local resources.

3. How long does treatment last?

Spina bifida requires monitoring and treatment throughout life. Initial surgical intervention occurs in the first days of life, with typical hospitalization of 1-2 weeks. However, this is only the first stage. Neurosurgical follow-up is necessary to monitor ventricular shunt function (when present) and evaluate tethered spinal cord. Urological follow-up is lifelong, with regular evaluations of renal and bladder function, adjustments in catheterization regimen, and treatment of recurrent urinary tract infections. Physical therapy and rehabilitation are continuous, adapting to needs at different developmental stages. Orthopedic follow-up monitors and treats progressive deformities of the spine and limbs. During the transition to adulthood, new needs emerge including career planning, independence, sexuality, and for women, pregnancy. Follow-up consultations are frequent in childhood (monthly or quarterly) and may become more spaced out in adulthood (annual), but engagement with health services is permanent.

4. Can this code be used in medical certificates?

Yes, the code LA02 can and should be used in official medical documentation, including certificates, medical reports, procedure requests, and documents for social benefit purposes. Spina bifida is a permanent congenital condition that frequently results in significant functional limitations, justifying the need for school, occupational, and social adaptations. In medical certificates, in addition to the code, it is important to describe the patient's specific functional limitations (such as reduced mobility, need for intermittent bladder catheterization, limitations for physical activities), as severity varies widely among individuals. For benefit requests or adaptations, detailed medical reports documenting the level of the lesion, degree of motor impairment, bowel and bladder function, associated complications, and ongoing treatments are more useful than simply the diagnostic code. Appropriate documentation facilitates access to appropriate rights and services.

5. Does spina bifida have different degrees of severity?

Yes, spina bifida presents a broad spectrum of severity. The mildest form, occult spina bifida, involves only minimal bone defect (usually non-fusion of the posterior arch of S1) without involvement of meninges or spinal cord, often asymptomatic and discovered incidentally on imaging studies. Meningocele represents intermediate severity, with herniation of meninges only through the bone defect, usually without significant neurological deficit, and favorable prognosis after surgical correction. Myelomeningocele is the most severe and most common form, with herniation of neural tissue, resulting in neurological deficits proportional to the level of the lesion. Higher lesions (thoracic) cause more extensive paraplegia and greater dependence, while sacral lesions may allow ambulation with orthoses. The presence of hydrocephalus, symptomatic Chiari malformation, and complications such as infections or tethered spinal cord increase severity. Functional prognosis depends on the anatomical level of the lesion, timing of surgical treatment, and quality of multidisciplinary follow-up.

6. Can children with spina bifida attend regular school?

Yes, most children with spina bifida have normal intellectual capacity and can attend regular school with appropriate adaptations. Intelligence is generally not affected by spina bifida itself, although complications such as severe hydrocephalus or ventricular shunt infections can occasionally impact cognitive development. Necessary adaptations include physical accessibility (ramps, adapted bathrooms, wheelchair space), allowing time for intermittent bladder catheterization (performed by school health professionals or by the child when older), flexibility for frequent medical appointments, and adapted physical education. Some children may present specific learning difficulties, particularly in mathematics and executive functions, benefiting from additional educational support. An inclusive school environment, with awareness among peers and teachers about the condition, is fundamental for healthy social and emotional development.

7. Is there prevention for spina bifida?

Yes, folic acid supplementation before conception and during the first weeks of pregnancy significantly reduces the risk of neural tube defects, including spina bifida. It is recommended that women of reproductive age consume 400-800 micrograms of folic acid daily, ideally starting three months before planned conception. Women with a previous history of pregnancy affected by neural tube defect or who use certain medications (such as anticonvulsants) require higher doses (4-5 milligrams daily) under medical guidance. Food fortification programs with folic acid, implemented in various countries, have demonstrated reduction in the incidence of neural tube defects at the population level. Other preventive measures include adequate control of pregestational maternal diabetes, avoiding hyperthermia in the first trimester (high fever, saunas), and avoiding teratogenic medications. Early prenatal diagnosis allows appropriate planning of delivery and immediate postnatal interventions, although it does not prevent the condition.

8. What is the life expectancy of people with spina bifida?

The life expectancy of people with spina bifida has improved dramatically in recent decades due to advances in surgical treatment, hydrocephalus management, urological care, and rehabilitation. Currently, most children born with spina bifida survive into adulthood. Life expectancy depends primarily on the severity of the lesion and quality of medical follow-up. Mild forms (meningocele, occult spina bifida) generally do not affect life expectancy. Myelomeningocele with good complication control allows survival into advanced adulthood, although it may be slightly reduced compared to the general population. The main causes of mortality include complications of hydrocephalus (shunt malfunction), renal insufficiency from inadequately treated bladder dysfunction, and recurrent infections. Rigorous multidisciplinary follow-up, adherence to intermittent bladder catheterization, monitoring of renal function, and early interventions in complications are fundamental to maximizing life expectancy and quality of life. Increasingly, adults with spina bifida achieve independence, higher education, employment, and start families.

Conclusion

Appropriate coding of spina bifida using the LA02 code from ICD-11 is fundamental for accurate documentation, health resource planning, epidemiological research, and ensuring access to the necessary multidisciplinary care. Understanding the diagnostic nuances, differentiation of related conditions, and recognition of the spectrum of severity of this condition allows appropriate coding and optimized clinical management. Health professionals should familiarize themselves with the new ICD-11 classification framework, ensuring appropriate transition and taking advantage of the improvements in specificity and diagnostic accuracy that the new system offers.
