What This Code Means
A54.33 is the ICD-10-CM diagnosis code for gonococcal keratitis. This is an eye infection caused by gonorrhea bacteria that affects the cornea (the clear front part of the eye). It can cause pain, redness, discharge, and vision problems if not treated promptly. A54.33 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering infections with a predominantly sexual mode of transmission (a50-a64).
A54.33 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.
Verify documentation confirms gonococcal infection of the eye with corneal involvement; do not use this code for other causes of keratitis.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for A54.33 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify documentation confirms gonococcal infection of the eye with corneal involvement; do not use this code for other causes of keratitis
- •This code is part of the gonococcal infection hierarchy (A54.-), so ensure the primary diagnosis reflects the gonococcal nature and that no conflicting eye infection codes are assigned
