What This Code Means
H44.512 is the ICD-10-CM diagnosis code for absolute glaucoma, left eye. Complete loss of vision and function in the left eye, typically resulting from severe glaucoma or trauma. H44.512 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of vitreous body and globe (h43-h44).
H44.512 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 code indicates the eye has progressed to absolute glaucoma stage with no functional vision.
