About B94.8
B94.8 is the ICD-10-CM diagnosis code for sequelae of other specified infectious and parasitic diseases. It belongs to category B94 (sequelae of other and unspecified infectious and parasitic diseases), block B90-B94 (sequelae of infectious and parasitic diseases) and chapter 1 (certain infectious and parasitic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within B94, choose B94.8 (other specified infectious and parasitic diseases) only when documentation doesn't support a more specific option: trachoma (B94.0), viral encephalitis (B94.1), viral hepatitis (B94.2) and unspecified infectious and parasitic disease (B94.9).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 867 (Other Infectious and Parasitic Diseases Diagnoses with MCC, relative weight 2.1859), DRG 868 (Other Infectious and Parasitic Diseases Diagnoses with CC, relative weight 1.0235) and DRG 869 (Other Infectious and Parasitic Diseases Diagnoses without CC/MCC, relative weight 0.6787), in MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 139.8 (late effects of other and unspecified infectious and parasitic diseases).
