About coding Empyema tuberculosis
The ICD-10-CM code for Empyema tuberculosis is A15.6 (Tuberculous pleurisy).
Within A15 (respiratory tuberculosis), A15.6 is specifically for tuberculous pleurisy. Related codes cover tuberculosis of lung (A15.0), tuberculosis of intrathoracic lymph nodes (A15.4), tuberculosis of larynx, trachea and bronchus (A15.5), primary respiratory tuberculosis (A15.7), other respiratory tuberculosis (A15.8) and unspecified (A15.9).
Don't report A15.6 together with the conditions in its Excludes1 note: primary respiratory tuberculosis (A15.7).
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.

- primary respiratory tuberculosis (A15.7)
