BillableUnspecifiedMCC

Is Q22.9 billable?

Yes, but Q22.9 is an unspecified code. Q22.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, Q22.9 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting Q22.9 — the more specific alternatives are listed below.

Which MS-DRGs does Q22.9 group to?

Q22.9 sits in MDC 05 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 306Cardiac Congenital and Valvular Disorders with MCCmedical

As a secondary diagnosis, Q22.9 is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG.
