| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| M62.50 | Muscle wasting and atrophy, not elsewhere classified, unspecified site | Use when muscle atrophy is present without a specified cause or site. |
|
| M62.84 | Sarcopenia | Use for age-related muscle loss with functional decline. |

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
- Presence of significant muscle loss on imaging
documentation Criteria
- Detailed muscle strength assessment
Applicable To

- Normal nerve conduction studies
Code-Specific Risks
- Confusion with M62.81 for muscle weakness
Coding Notes
- Ensure imaging supports the diagnosis to avoid denials.
M62.84 - Sarcopenia
Use for age-related muscle loss with functional decline.
Applicable To
- Age-related muscle loss
Clinical Validation Requirements
- Grip strength <27 kg (men)/<16 kg (women)
- SARC-F score ≥4
Coding Notes
Document functional impact and muscle strength measurements.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Muscle Atrophy to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M62.50.
Impact
Clinical: Inadequate clinical assessment, Regulatory: Potential for audit issues, Financial: Risk of claim denials
Mitigation Strategy
Use specific muscle strength grades, Include imaging results
Impact
Reimbursement: Incorrect DRG assignment may affect reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use M62.84 for sarcopenia to ensure accurate coding.
Impact
High denial rates for M62.50 without imaging support.
Mitigation Strategy
Ensure all claims include appropriate imaging documentation.
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.
