| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| M62.561 | Atrophy of muscle, lower leg | Use for atrophy localized to lower leg muscles confirmed by imaging or strength testing. |
|
| M62.50 | Muscle wasting and atrophy, unspecified | Use when the specific site of muscle atrophy is not documented. |

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 leg muscle atrophy
Decision Criteria
clinical Criteria
- MRI or CT evidence of muscle volume loss
documentation Criteria
- Detailed muscle strength grading and measurements
Applicable To
- Calf muscle atrophy
Excludes
- Generalized muscle weakness (M62.81)
Clinical Validation Requirements
- MRI showing muscle volume loss
- Strength testing ≤3/5 on MRC scale
Code-Specific Risks
- Misclassification with generalized weakness codes
Coding Notes
- Ensure documentation specifies laterality and underlying cause if known.
M62.50 - Muscle wasting and atrophy, unspecified
Use when the specific site of muscle atrophy is not documented.
Applicable To
- General muscle wasting
Excludes
- Localized muscle atrophy (M62.561)
Clinical Validation Requirements
- Generalized weakness without specific localization
Coding Notes
Avoid using when specific muscle group is documented.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Mitochondrial myopathy, not elsewhere classified
G72.5Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Leg Muscle Atrophy to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M62.561.
Impact
Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to lack of specificity.
Mitigation Strategy
Use specific terms like 'atrophy' with measurements, Include imaging results when available
Impact
Reimbursement: May result in lower reimbursement due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Use M62.561 when atrophy is localized to the lower leg.
Impact
Risk of audits due to use of unspecified codes when specific documentation is available.
Mitigation Strategy
Ensure documentation includes specific muscle group and measurements.
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.
