| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| K60.31 | Simple anal fistula | Use for superficial anal fistulas not involving sphincter muscles. |
|
| K60.32 | Complex anal fistula | Use when the fistula tract involves sphincter muscles or has multiple tracts. |
|
| K60.5 | Fistula with abscess | Use when a fistula is accompanied by an abscess. |

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

Decision Criteria
clinical Criteria
- Fistula tract does not involve sphincter muscles
Applicable To
- Subcutaneous fistula
Excludes
- Rectal fistula (K60.4xx)
Clinical Validation Requirements
- Documentation of superficial fistula tract not involving sphincter muscles
Code-Specific Risks
- Risk of undercoding if complexity is not assessed
Coding Notes
- Ensure documentation specifies the lack of sphincter involvement.
K60.32 - Complex anal fistula
Use when the fistula tract involves sphincter muscles or has multiple tracts.
Applicable To
- Transsphincteric fistula
- Suprasphincteric fistula
Excludes
- Rectal fistula (K60.4xx)
Clinical Validation Requirements
- MRI or ultrasound confirmation of fistula tract involving sphincter muscles
Coding Notes
Ensure imaging confirms complexity.
K60.5 - Fistula with abscess
Use when a fistula is accompanied by an abscess.
Applicable To
- Fistula-associated perianal abscess
Clinical Validation Requirements
- Culture results confirming abscess presence
Coding Notes
Document abscess culture results.
Ancillary Codes

K61.1Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Anal Fistula to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K60.31.
Impact
Clinical: Misdiagnosis leading to inappropriate treatment, Regulatory: Non-compliance with coding standards, Financial: Incorrect billing and potential claim denials
Mitigation Strategy
Verify diagnosis with imaging, Educate staff on anatomical differences
Impact
Reimbursement: Potential underpayment due to lack of specificity, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data representation
Mitigation Strategy
Require MRI/EUS documentation of tract anatomy
Impact
Coding without specifying fistula complexity or sphincter involvement
Mitigation Strategy
Require detailed imaging and operative reports for all fistula cases
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.
