Tuberculous episcleritis

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

This is an infection of the episclera (the tissue layer covering the white part of the eye) caused by tuberculosis bacteria. It represents a rare complication of tuberculosis that affects the eye.

Coding Tips

  • •This code requires confirmation of tuberculosis diagnosis - ensure documentation specifies tuberculous etiology rather than other causes of episcleritis
  • •This is a manifestation code of extrapulmonary tuberculosis; verify if a primary TB site code (such as A15-A19) should also be reported to capture the complete clinical picture
