ICD-10 code for DMAC

The ICD-10-CM code for DMAC is A31.2 (Disseminated mycobacterium avium-intracellulare complex (DMAC)).

Within A31 (infection due to other mycobacteria), A31.2 is specifically for disseminated mycobacterium avium-intracellulare complex (DMAC). Related codes cover pulmonary mycobacterial infection (A31.0), cutaneous mycobacterial infection (A31.1), other mycobacterial infections (A31.8) and mycobacterial infection, unspecified (A31.9).

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.

In MS-DRG v44.0, it is part of the grouping logic for DRG 867 (Other Infectious and Parasitic Diseases Diagnoses with MCC, relative weight 2.1859), DRG 868 (Other Infectious and Parasitic Diseases Diagnoses with CC, relative weight 1.0235), DRG 869 (Other Infectious and Parasitic Diseases Diagnoses without CC/MCC, relative weight 0.6787), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506), DRG 975 (HIV with Major Related Condition with CC, relative weight 1.3252) and DRG 976 (HIV with Major Related Condition without CC/MCC, relative weight 0.8124), in MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites) and MDC 25 (Human Immunodeficiency Virus Infections), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
