About coding otitis media tuberculosis
The ICD-10-CM code for otitis media tuberculosis is A18.6 (Tuberculosis of (inner) (middle) ear).
Within A18 (tuberculosis of other organs), A18.6 is specifically for tuberculosis of (inner) (middle) ear. Related codes cover tuberculosis of bones and joints (A18.0), tuberculosis of genitourinary system (A18.1), tuberculous peripheral lymphadenopathy (A18.2), tuberculosis of intestines, peritoneum and mesenteric glands (A18.3), tuberculosis of skin and subcutaneous tissue (A18.4), tuberculosis of eye (A18.5), tuberculosis of adrenal glands (A18.7) and tuberculosis of other specified organs (A18.8).
The conditions in its Excludes2 note aren't part of A18.6, but may be coded alongside it if the patient has both: tuberculosis of external ear (A18.4) and tuberculous mastoiditis (A18.03).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
