B76.9 — Hookworm disease, unspecified
Is B76.9 billable?
Yes, but B76.9 is an unspecified code. B76.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, B76.9 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 B76.9 — the more specific alternatives are listed below.

Which MS-DRGs does B76.9 group to?
B76.9 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.
- 371Major Gastrointestinal Disorders and Peritoneal Infections with MCCmedical
- 372Major Gastrointestinal Disorders and Peritoneal Infections with CCmedical
- 373Major Gastrointestinal Disorders and Peritoneal Infections without CC/MCCmedical
As a secondary diagnosis, B76.9 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
