Decision Criteria
clinical Criteria
- Imaging confirms ventriculomegaly with patent ventricular pathways.
coding Criteria
- Underlying condition such as meningitis should be coded first if present.
Applicable To
- Hydrocephalus with patent ventricular pathways
Excludes
- Obstructive hydrocephalus (G91.1)
Clinical Validation Requirements
- MRI/CT showing ventriculomegaly without intraventricular obstruction
- CSF flow obstruction at basal cisterns
Code-Specific Risks
- Incorrectly using G91.9 when specific type is known
Coding Notes
- Ensure documentation specifies the type of hydrocephalus and any underlying conditions.
Ancillary Codes

G91.1Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Communicating Hydrocephalus to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G91.0.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Increases risk of non-compliance with coding standards., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Ensure imaging results are included in the medical record., Train staff on documentation requirements.
Impact
Reimbursement: May result in lower reimbursement due to unspecified coding., Compliance: Increases risk of audits for unspecified coding., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Use G91.0 for communicating hydrocephalus when confirmed by imaging.
Impact
Using G91.9 when specific type is known.
Mitigation Strategy
Ensure documentation supports the specific type of hydrocephalus.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
