R76.11Nonspecific reaction to tuberculin skin test without active tuberculosis

R76.11 is the ICD-10-CM diagnosis code for nonspecific reaction to tuberculin skin test without active tuberculosis. It belongs to category R76 (other abnormal immunological findings in serum), block R70-R79 (abnormal findings on examination of blood, without diagnosis) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within R76.1, choose R76.11 (tuberculin skin test without active tuberculosis) only when documentation doesn't support a more specific option: cell mediated immunity measurement of gamma interferon antigen response without active tuberculosis (R76.12).

Don't report R76.11 together with the conditions in its Excludes1 note: nonspecific reaction to cell mediated immunity measurement of gamma interferon antigen response without active tuberculosis (R76.12).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 177 (Respiratory Infections and Inflammations with MCC, relative weight 1.6092), DRG 178 (Respiratory Infections and Inflammations with CC, relative weight 0.9744) and DRG 179 (Respiratory Infections and Inflammations without CC/MCC, relative weight 0.7345), in MDC 04 (Diseases and Disorders of the Respiratory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 795.51 (nonspecific reaction to tuberculin skin test without active tuberculosis).
