| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I68.0 | Cerebral amyloid angiopathy | Use for sporadic CAA without systemic amyloidosis. |
|
| E85.4 | Hereditary amyloidosis | Use when CAA is due to hereditary amyloidosis. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

coding Criteria
- Sequence after systemic amyloidosis code if applicable
Applicable To
- CAA without systemic involvement
Excludes
- Traumatic intracerebral hemorrhage
- Hypertensive hemorrhage
Clinical Validation Requirements

- Absence of hypertension
Code-Specific Risks
- Incorrect sequencing with systemic amyloidosis codes
Coding Notes
- Ensure proper sequencing with systemic amyloidosis codes.
E85.4 - Hereditary amyloidosis
Use when CAA is due to hereditary amyloidosis.
Applicable To
- Hereditary cerebral amyloid angiopathy
Excludes
- Non-hereditary forms of amyloidosis
Clinical Validation Requirements
- Genetic testing confirming hereditary amyloidosis
Coding Notes
Ensure genetic confirmation is documented.
Ancillary Codes

R29.81Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Cerebral Amyloid Angiopathy to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I68.0.
Impact
Clinical: Misdiagnosis of hereditary conditions., Regulatory: Non-compliance with genetic documentation standards., Financial: Potential reimbursement issues.
Mitigation Strategy
Ensure genetic testing is ordered and results documented.
Impact
Reimbursement: May lead to incorrect DRG assignment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Sequence E85.4 first if hereditary amyloidosis is present.
Impact
Incorrect sequencing of CAA and amyloidosis codes.
Mitigation Strategy
Review coding guidelines for correct sequencing.
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.
