P37.8 — Other specified congenital infectious and parasitic diseases
Is P37.8 billable?
Yes, but P37.8 is an unspecified code. P37.8 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, P37.8 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 P37.8 — the more specific alternatives are listed below.

Which MS-DRGs does P37.8 group to?
P37.8 sits in MDC 15 and helps define the logic of 1 MS-DRG (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

As a secondary diagnosis, P37.8 is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG.
