ICD-10 code for human herpes

The ICD-10-CM code for human herpes is B00.9 (Herpesviral infection, unspecified). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on B00.9.

Within B00, choose B00.9 (Herpesviral infection, unspecified) only when documentation doesn't support a more specific option: eczema herpeticum (B00.0), herpesviral vesicular dermatitis (B00.1), herpesviral gingivostomatitis and pharyngotonsillitis (B00.2), herpesviral meningitis (B00.3), herpesviral encephalitis (B00.4), herpesviral ocular disease (B00.5), disseminated herpesviral disease (B00.7) and other forms of herpesviral infections (B00.8).

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 606 (Minor Skin Disorders with MCC, relative weight 1.5728), DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506), DRG 975 (HIV with Major Related Condition with CC, relative weight 1.3252) and DRG 976 (HIV with Major Related Condition without CC/MCC, relative weight 0.8124), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast) and MDC 25 (Human Immunodeficiency Virus Infections), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
