B02.30 — Zoster ocular disease, unspecified
Is B02.30 billable?
Yes, but B02.30 is an unspecified code. B02.30 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, B02.30 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 B02.30 — the more specific alternatives are listed below.

Which MS-DRGs does B02.30 group to?
B02.30 sits in MDC 02 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.
