Compare key differences between these codes to ensure accurate selection
| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| G91.0 | Communicating hydrocephalus | Use when hydrocephalus is due to CSF absorption failure without obstruction. |
|
| G91.1 | Obstructive hydrocephalus | Use when there is a blockage in the ventricular system causing hydrocephalus. |
|
| G91.2 | Normal pressure hydrocephalus | Use when the clinical triad and imaging findings are present. |
|

Documentation & Coding Risks
Avoid these common issues when documenting Hydrocephalus.
Failing to document imaging findings
Impact
Clinical: May lead to misdiagnosis., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims.
Mitigation
Always include imaging results in documentation., Use structured templates.
Using G91.9 when specific type is known
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.
Mitigation
Ensure documentation specifies the type of hydrocephalus.
Specificity of hydrocephalus type
Impact
Audits may focus on whether the type of hydrocephalus is specified.
Mitigation
Ensure documentation includes specific type and supporting evidence.
