| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| K52.1 | Toxic gastroenteritis and colitis | Use when colitis or gastroenteritis is confirmed as drug-induced by chemotherapy. |

- Ensure documentation specifies the link between chemotherapy and colitis.
T45.1X5A - Adverse effect of antineoplastic and immunosuppressive drugs, initial encounter
Use when documenting the adverse effect of chemotherapy drugs.
Applicable To
- Adverse effect of chemotherapy drugs
Excludes
- Poisoning by antineoplastic drugs (T45.1X1)
Clinical Validation Requirements
- Documentation of chemotherapy administration
- Temporal relationship between drug administration and symptom onset
Coding Notes
Ensure proper sequencing with primary condition codes.

T45.1X5ADocumentation & Coding Risks
Avoid these common documentation and coding issues when documenting Chemotherapy-Induced Diarrhea to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K52.1.
Impact
Clinical: May lead to under-treatment or mismanagement., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims or incorrect billing.
Mitigation Strategy
Ensure documentation specifies colitis if present., Use diagnostic tests to confirm colitis.
Impact
Reimbursement: Incorrect coding may lead to denied claims or incorrect DRG assignment., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate clinical data affecting patient records.
Mitigation Strategy
Query provider to confirm whether colitis/gastroenteritis is present.
Impact
Improper sequencing of primary and secondary codes.
Mitigation Strategy
Educate staff on correct sequencing rules and provide coding guidelines.
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.
