What This Code Means

H02.23A is the ICD-10-CM diagnosis code for paralytic lagophthalmos right eye, upper and lower eyelids. Weakness or paralysis affecting both the upper and lower eyelids of the right eye. H02.23A 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).

H02.23A is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.

Use when both eyelids of the same eye are affected by paralysis.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for H02.23A sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
