| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| K12.3 | Oral mucositis (ulcerative) | Use when oral mucositis is present without a specified cause. |
|
| K12.31 | Mucositis (ulcerative) due to antineoplastic therapy | Use when mucositis is directly linked to chemotherapy treatment. |
|
| K12.33 | Mucositis (ulcerative) due to radiation | Use when mucositis is directly linked to radiation therapy. |
|
| K92.81 | Gastrointestinal mucositis (ulcerative) | Use when mucositis affects the gastrointestinal tract due to drug therapy. |

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
- Ulcerative lesions without a specified cause
Applicable To
- Ulcerative oral mucositis
Excludes
- Necrotizing stomatitis (A69.0)
Clinical Validation Requirements
- Presence of ulcerative lesions in the oral cavity
- No specific cause identified
Code-Specific Risks
- Risk of undercoding if specific cause is known but not documented
Coding Notes
- Ensure documentation specifies the absence of a specific cause if using this code.
K12.31 - Mucositis (ulcerative) due to antineoplastic therapy
Use when mucositis is directly linked to chemotherapy treatment.
Applicable To
- Chemotherapy-induced oral mucositis
Clinical Validation Requirements
- Documentation of chemotherapy as the cause
- Presence of ulcerative lesions in the oral cavity
Coding Notes
Ensure chemotherapy is documented as the cause.
K12.33 - Mucositis (ulcerative) due to radiation
Use when mucositis is directly linked to radiation therapy.
Applicable To
- Radiation-induced oral mucositis
Clinical Validation Requirements
- Documentation of radiation therapy as the cause
- Presence of ulcerative lesions in the oral cavity
Coding Notes
Ensure radiation is documented as the cause.
K92.81 - Gastrointestinal mucositis (ulcerative)
Use when mucositis affects the gastrointestinal tract due to drug therapy.
Applicable To
- Drug-induced gastrointestinal mucositis
Clinical Validation Requirements
- Presence of ulcerative lesions in the gastrointestinal tract
- Documentation of drug therapy as the cause
Coding Notes
Ensure documentation specifies the gastrointestinal location and drug cause.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes

A69.0Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Mucositis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K12.3.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to lack of specificity.
Mitigation Strategy
Use structured templates for documentation, Ensure thorough review of patient treatment history
Impact
Reimbursement: May lead to lower reimbursement due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Use specific subcodes like K12.31 or K12.33 when the cause is known.
Impact
Audits may focus on whether the cause of mucositis is documented and coded correctly.
Mitigation Strategy
Implement regular training on documentation and coding specificity.
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.
