| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I78.0 | Hereditary hemorrhagic telangiectasia | Use when hereditary hemorrhagic telangiectasia is confirmed by clinical criteria or genetic testing. |
|
| I78.1 | Non-neoplastic nevus | Use for localized telangiectasia without hereditary or systemic features. |
|
| K55.21 | Angiodysplasia of colon without hemorrhage | Use when colonic telangiectasia is confirmed without active bleeding. |
|
| K55.22 | Angiodysplasia of colon with hemorrhage | Use when colonic telangiectasia is confirmed with active bleeding. |

Z83.89Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Telangiectasia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I78.0.
Impact
Clinical: May lead to misdiagnosis or inappropriate treatment, Regulatory: Non-compliance with documentation standards, Financial: Potential claim denials or reduced reimbursement
Mitigation Strategy
Use structured templates for documentation, Ensure all clinical criteria are recorded
Impact
Reimbursement: Incorrect sequencing may lead to denied claims, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data representation
Mitigation Strategy
Sequence K62.8 (rectum) → I78.1
Impact
Reimbursement: Claims may be rejected due to outdated coding, Compliance: Violation of current coding standards, Data Quality: Outdated data affecting clinical records
Mitigation Strategy
Use K55.21/K55.22 + I78.1
Impact
Incorrect sequencing or use of outdated codes
Mitigation Strategy
Regular training on current coding guidelines and updates
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.
