What This Code Means
H53.439 is the ICD-10-CM diagnosis code for sector or arcuate defects, unspecified eye. A wedge or arc-shaped missing area in the peripheral vision when it is unclear which eye or eyes are affected. H53.439 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering visual disturbances and blindness (h53-h54).
H53.439 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, 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 this code only when laterality cannot be determined from documentation.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for H53.439 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
