Question 1

What is ICD-10 code M62.061?

Accepted Answer

M62.061 is the ICD-10-CM diagnosis code for separation of muscle (nontraumatic), right lower leg. A spontaneous separation or tearing of muscle fibers in the right lower leg that occurs without trauma or injury. M62.061 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering disorders of muscles (m60-m63).

M62.061 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

Ensure documentation confirms nontraumatic etiology to avoid miscoding traumatic ruptures.

Question 2

Is M62.061 an HCC code?

Accepted Answer

No. M62.061 is a billable ICD-10-CM code but does not map to any payment HCC category under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can still be reported on Medicare Advantage encounter data submissions, but it does not contribute to the beneficiary's Risk Adjustment Factor (RAF) score and therefore does not affect the risk-adjusted capitation payment to the plan. V28 reached 100% phase-in for payment year 2026.

Question 3

Is M62.061 billable?

Accepted Answer

Yes. M62.061 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. M62.061 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

Question 4

What is the V28 vs V24 difference for M62.061?

Accepted Answer

M62.061 does not map to a payment HCC under either the CMS-HCC V28 risk adjustment model or the older V24 model. V28 reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition. Because neither community model rewards M62.061 with a risk adjustment factor, it contributes zero to a Medicare Advantage beneficiary's V28/V24 community RAF score in either version. Coders should check whether provider documentation supports a more specific child code that does map to a community payment HCC.

Question 5

What should coders know when reporting M62.061?

Accepted Answer

Ensure documentation confirms nontraumatic etiology to avoid miscoding traumatic ruptures Verify right lower leg is the correct anatomical site; lower leg extends from knee to ankle
