Is M79.673 an HCC code?

What This Code Means
M79.673 is the ICD-10-CM diagnosis code for pain in unspecified foot. Pain in the foot when the specific side is not documented or when both feet are affected. M79.673 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering other soft tissue disorders (m70-m79).
M79.673 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.
Assign only when laterality cannot be determined from the medical record.

Coding Tips
- •Assign only when laterality cannot be determined from the medical record
