| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C32.0 | Malignant neoplasm of glottis | Use when the tumor is located in the glottis, involving true vocal cords. |
|
| C32.1 | Malignant neoplasm of supraglottis | Use when the tumor is located in the supraglottis. |
|
| C32.8 | Malignant neoplasm of overlapping sites of larynx | Use when the tumor spans multiple laryngeal subsites. |
|
| C32.9 | Malignant neoplasm of unspecified site of larynx | Use only when the specific subsite cannot be determined. |

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

Primary ICD-10-CM Codes for larynx cancer
Decision Criteria
clinical Criteria
- Confirmed glottic tumor via imaging and biopsy
Applicable To
- Tumors involving true vocal cords
Excludes
- Benign neoplasms of the glottis
Clinical Validation Requirements
- Laryngoscopy images showing vocal cord lesion
- Biopsy report specifying 'glottic'
Code-Specific Risks
- Incorrectly coding as unspecified when glottic involvement is documented.
Coding Notes
- Ensure documentation specifies 'glottic' to avoid defaulting to unspecified codes.
C32.1 - Malignant neoplasm of supraglottis
Use when the tumor is located in the supraglottis.
Applicable To
- Tumors involving epiglottis, false vocal cords
Excludes
- Benign neoplasms of the supraglottis
Clinical Validation Requirements
- Imaging confirming supraglottic mass
- Biopsy report specifying 'supraglottic'
Coding Notes
Ensure documentation specifies 'supraglottic' to avoid defaulting to unspecified codes.
C32.8 - Malignant neoplasm of overlapping sites of larynx
Use when the tumor spans multiple laryngeal subsites.
Applicable To
- Tumors spanning multiple laryngeal subsites
Excludes
- Benign neoplasms of overlapping sites
Clinical Validation Requirements
- Operative note indicating tumor spans multiple subsites
- Diagrammatic mapping of tumor location
Coding Notes
Ensure documentation specifies overlapping sites to avoid defaulting to unspecified codes.
C32.9 - Malignant neoplasm of unspecified site of larynx
Use only when the specific subsite cannot be determined.
Applicable To
- Laryngeal cancer without specified subsite
Excludes
- Benign neoplasms of the larynx
Clinical Validation Requirements
- Pathology report stating 'larynx' without subsite
- Negative imaging for localization
Coding Notes
Use only when no specific subsite can be determined from available documentation.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Tobacco use
Z72.0Alcohol abuse
F10.-Secondary malignant neoplasm of other specified sites
C78.89Personal history of tobacco use
Z87.891Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Larynx Cancer to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C32.0.
Impact
Clinical: May affect treatment planning and surgical approach., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to insufficient documentation.
Mitigation Strategy
Ensure laterality is documented in all relevant reports, Use templates that prompt for laterality
Impact
Reimbursement: May lead to incorrect DRG assignment, affecting reimbursement., Compliance: Non-compliance with coding guidelines requiring specificity., Data Quality: Decreases accuracy of clinical data used for research and treatment planning.
Mitigation Strategy
Query the provider for specific subsite details if not documented.
Impact
Using C32.9 without documented rationale for unspecified site.
Mitigation Strategy
Implement queries to obtain specific subsite information.
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.
