R76.12

Billable

Nonspecific reaction to cell mediated immunity measurement of gamma interferon antigen response without active tuberculosis

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

What This Code Means

An interferon-gamma release assay (IGRA) test for TB shows a positive response, but the person does not have active tuberculosis disease.

Coding Tips

  • •This test measures immune response to TB antigens and suggests latent TB infection or prior TB exposure
  • •Coordinate with R76.11 findings if both skin test and IGRA are performed; document which test was used

Excludes 1 — Do NOT code together

  • nonspecific reaction to tuberculin skin test without active tuberculosis (R76.11)
  • positive tuberculin skin test (R76.11)
