Understanding Myelomeningocele Without Hydrocephalus (LA02.01)

Myelomeningocele without hydrocephalus, identified by the ICD-11 code LA02.01, is a severe form of spina bifida, which is a type of neural tube defect (NTD). This condition arises from the incomplete closure of the neural tube during fetal development, specifically affecting the spine and spinal cord. It is characterized by nerve damage resulting from the spinal cord and its protective membranes protruding through an opening in the backbone.

Other Names for Myelomeningocele Without Hydrocephalus

This condition is also referred to by several other terms, including:
  • Total spina bifida cystica without hydrocephalus
  • Thoracolumbosacral spina bifida cystica without hydrocephalus
  • Lumbosacral spina bifida cystica without hydrocephalus
  • Cervical spina bifida cystica without hydrocephalus
  • Cervicothoracic spina bifida cystica without hydrocephalus
  • Upper thoracic spina bifida cystica without hydrocephalus
In patient-friendly terms, it is often described as open spina bifida.

The Origins of Myelomeningocele Without Hydrocephalus

The primary cause of myelomeningocele without hydrocephalus is the failure of the neural tube to close completely during the early stages of fetal development, typically within the first four weeks of pregnancy. While the exact cause is complex and not fully understood, factors such as genetic predispositions, nutritional deficiencies (particularly low folic acid levels), and certain environmental influences are believed to contribute to its occurrence.

Identifying Myelomeningocele Without Hydrocephalus

The presentation of myelomeningocele without hydrocephalus involves significant nerve damage. Symptoms can vary depending on the location and extent of the spinal lesion but may include weakness or paralysis of the body parts below the affected area, loss of bladder and bowel control, and sensory deficits. Associated conditions can include syringomyelia and hip dislocation.

How Myelomeningocele Without Hydrocephalus is Diagnosed

Diagnosis can often be made during pregnancy through prenatal screening. A maternal blood test measuring alpha-fetoprotein (AFP) may indicate an elevated level, prompting further investigation. Fetal ultrasound, particularly during the second trimester, is a highly accurate method for diagnosing myelomeningocele. Postnatal diagnosis typically involves imaging tests such as MRI or CT scans if not identified prenatally.

Approaches to Myelomeningocele Without Hydrocephalus

Treatment for myelomeningocele without hydrocephalus primarily involves surgical repair of the opening in the spine. This surgery can be performed either before birth (fetal surgery) or shortly after birth (postnatal surgery), ideally within the first 48 hours. While surgery aims to reduce infection risk and prevent further damage, it cannot correct existing nerve damage. Lifelong management and therapy are often required to address the functional impairments resulting from the condition.

Documentation and Coding for Myelomeningocele Without Hydrocephalus

For accurate medical record-keeping and billing, the ICD-11 code LA02.01 is used to specifically identify Myelomeningocele without hydrocephalus. This precise coding is essential for clinical documentation, statistical reporting, and ensuring appropriate reimbursement for healthcare services related to this condition.

Frequently asked questions

What is the ICD-11 classification meaning of Myelomeningocele without hydrocephalus (LA02.01)?
Myelomeningocele without hydrocephalus (LA02.01) is classified in ICD-11 as a condition caused by the failure of the neural tube to close completely during fetal development, characterized by nerve damage.
How does ICD-11 differentiate Myelomeningocele without hydrocephalus from Myelomeningocele with hydrocephalus?
ICD-11 differentiates Myelomeningocele without hydrocephalus (LA02.01) from Myelomeningocele with hydrocephalus (LA02.00) by the presence or absence of hydrocephalus.
What is the primary characteristic of Myelomeningocele without hydrocephalus (LA02.01) as per ICD-11?
The primary characteristic of Myelomeningocele without hydrocephalus (LA02.01) in ICD-11 is nerve damage.
Can Myelomeningocele without hydrocephalus (LA02.01) be further specified in ICD-11 coding?
Yes, Myelomeningocele without hydrocephalus (LA02.01) allows for post-coordination with stem and/or extension codes to add detail to the condition.
