What This Code Means
H44.122 is the ICD-10-CM diagnosis code for parasitic endophthalmitis, unspecified, left eye. A parasitic infection inside the left eye causing inflammation and potential vision loss. H44.122 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).
H44.122 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.
Ensure laterality is correctly documented as left eye to distinguish from right eye (H44.121) or bilateral cases.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for H44.122 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Ensure laterality is correctly documented as left eye to distinguish from right eye (H44.121) or bilateral cases
- •Consider whether the patient has systemic parasitic infection requiring broader treatment
