Is C48.2 billable?

Yes, but C48.2 is an unspecified code. C48.2 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, C48.2 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 C48.2 — the more specific alternatives are listed below.

Which MS-DRGs does C48.2 group to?

C48.2 sits in MDC 06 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 374Digestive Malignancy with MCCmedical
  • 375Digestive Malignancy with CCmedical
  • 376Digestive Malignancy without CC/MCCmedical

As a secondary diagnosis, C48.2 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from C48

The conditions below can never be reported together with C48.2 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • Kaposi's sarcoma of connective tissue (C46.1)
  • mesothelioma (C45.-)

How long has C48.2 existed?

C48.2 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
