What This Code Means
H02.233 is the ICD-10-CM diagnosis code for paralytic lagophthalmos right eye, unspecified eyelid. This condition occurs when the right eye cannot fully close due to weakness or paralysis of the eyelid muscles, leaving part of the eye exposed during sleep or blinking. This can lead to dry eye and potential corneal damage if untreated. H02.233 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).
H02.233 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 laterality is documented as right eye; if bilateral, use separate codes for each eye (H02.232 for left eye).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H02.233 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify laterality is documented as right eye; if bilateral, use separate codes for each eye (H02.232 for left eye)
- •Ensure the paralytic nature is confirmed in documentation; if the cause is known (e.g., Bell's palsy, stroke), consider coding the underlying condition as well
