- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Not Chronic
O98.02 is a billable ICD-10-CM diagnosis code for tuberculosis complicating childbirth. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 998. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 226 closely related codes. The code is restricted by the Medicare Code Editor to maternity cases (age 9 through 64). Coders also document this condition as maternal tuberculosis during pregnancy, childbirth and/or puerperium. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Complications specified during childbirth and Tuberculosis.
