Is H50.689 an HCC code?
No. H50.689 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
H50.689 is the ICD-10-CM diagnosis code for extraocular muscle entrapment, unspecified, unspecified eye. An extraocular muscle is trapped or restricted, but neither the specific muscle nor the specific eye is identified. H50.689 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of ocular muscles, binocular movement, accommodation and refraction (h49-h52).
H50.689 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.
This is the least specific entrapment code; use only when neither muscle type nor laterality can be determined.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H50.689 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This is the least specific entrapment code; use only when neither muscle type nor laterality can be determined
