About A18.7
A18.7 is the ICD-10-CM diagnosis code for tuberculosis of adrenal glands. It belongs to category A18 (tuberculosis of other organs), block A15-A19 (tuberculosis) and chapter 1 (certain infectious and parasitic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within A18 (tuberculosis of other organs), A18.7 is specifically for tuberculosis of adrenal glands. 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 (inner) (middle) ear (A18.6) and tuberculosis of other specified organs (A18.8).
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 643 (Endocrine Disorders with MCC, relative weight 1.6139), DRG 644 (Endocrine Disorders with CC, relative weight 1.0044), DRG 645 (Endocrine Disorders without CC/MCC, relative weight 0.7459), 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 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders) 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.
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 017.60 (tuberculosis of adrenal glands, unspecified).
