What This Code Means
H05.333 is the ICD-10-CM diagnosis code for deformity of bilateral orbits due to trauma or surgery. This code describes a permanent change in the shape or structure of both eye sockets (orbits) that resulted from an injury, accident, or surgical procedure. The deformity affects both sides of the face and may impact eye positioning or function. H05.333 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of eyelid, lacrimal system and orbit (h00-h05).
H05.333 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.
Verify that the deformity affects BOTH orbits (bilateral) - if only one side is affected, use H05.331 or H05.332 instead.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H05.333 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify that the deformity affects BOTH orbits (bilateral) - if only one side is affected, use H05.331 or H05.332 instead
- •Document the cause clearly in the medical record (trauma vs. surgery) as this helps justify the code selection and may require an additional external cause code (W, X, or Y codes) if trauma-related
