About coding Mantoux test abnormal
The ICD-10-CM code for Mantoux test abnormal is R76.11 (Nonspecific reaction to tuberculin skin test without active tuberculosis).
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.
Don't confuse with (Excludes1 for R76.11)
- nonspecific reaction to cell mediated immunity measurement of gamma interferon antigen response without active tuberculosis (R76.12)
