Range Overview
The ICD-10 code range Q10-Q17 refers to congenital malformations of the nervous system. These codes are used to document congenital anomalies such as anencephaly, spina bifida, congenital hydrocephalus, and other specified and unspecified congenital malformations of the nervous system. The codes provide a comprehensive classification of these conditions, allowing for detailed recording and tracking of these congenital disorders.
Key Usage Points:
- •Always code to the highest level of specificity.
- •Use additional codes to identify any associated underlying conditions.
- •Use additional code to identify any associated intellectual disabilities.
- •Do not use adult condition codes for congenital conditions.
- •Always verify codes in the ICD-10-CM book before finalizing.
Coding Guidelines
When to Use:
- ✓When a patient presents with a congenital malformation of the nervous system.
- ✓When a patient has a history of a congenital nervous system disorder.
- ✓When a patient's congenital nervous system disorder affects their current health status.
- ✓When a patient is being treated for complications related to a congenital nervous system disorder.
When NOT to Use:
- ✗When the patient's condition is acquired, not congenital.
- ✗When the patient's condition is not related to the nervous system.
- ✗When the patient's condition is a mental or behavioral disorder, not a nervous system disorder.
- ✗When the patient's condition is a neurological disorder, but not congenital.
Code Exclusions
Always verify exclusions in the ICD-10-CM book before finalizing the code.
Documentation Requirements
Documentation for congenital malformations of the nervous system should be comprehensive, detailing the specific condition, its severity, any associated conditions, and the impact on the patient's health status. The documentation should also include any relevant history and examination findings.
Clinical Information:
- •Specific diagnosis
- •Severity of the condition
- •Associated conditions
- •Impact on health status
- •History and examination findings
Supporting Evidence:
- •Medical history records
- •Physical examination notes
- •Laboratory test results
- •Imaging studies
Good Documentation Example:
Patient diagnosed with congenital hydrocephalus, severe, with associated intellectual disability. History of multiple shunt revisions.
Poor Documentation Example:
Patient has hydrocephalus.
Common Documentation Errors:
- âš Not documenting the specific diagnosis
- âš Not documenting the severity of the condition
- âš Not documenting associated conditions
- âš Not documenting the impact on health status
Range Statistics
Coding Complexity
Coding for congenital malformations of the nervous system can be complex due to the need to understand the specific diagnosis, identify any associated conditions, determine the impact on the patient's health status, and navigate the exclusions. However, with thorough documentation and careful coding, these challenges can be managed.
Key Factors:
- â–¸Understanding the specific diagnosis
- â–¸Identifying associated conditions
- â–¸Determining the impact on health status
- â–¸Navigating the exclusions
Specialty Focus
These codes are primarily used by pediatricians, neurologists, and neurosurgeons. They are also used by other specialists who manage patients with congenital malformations of the nervous system.
Primary Specialties:
Clinical Scenarios:
- • Newborn diagnosed with anencephaly.
- • Child with spina bifida presenting for follow-up.
- • Adult with history of congenital hydrocephalus presenting with headache.
- • Patient with congenital malformation of the nervous system presenting with seizures.

Frequently Asked Questions
Can I use these codes for acquired conditions of the nervous system?
No, these codes are specifically for congenital malformations of the nervous system. Acquired conditions should be coded using their respective codes in the ICD-10-CM.
