About coding whitlow herpes
The ICD-10-CM code for whitlow herpes is B00.89 (Other herpesviral infection).
Within B00.8, choose B00.89 (Other herpesviral infection) only when documentation doesn't support a more specific option: herpesviral hepatitis (B00.81) and herpes simplex myelitis (B00.82).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 791 (Prematurity with Major Problems, relative weight 4.1075), DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), DRG 865 (Viral Illness with MCC, relative weight 1.3485), DRG 866 (Viral Illness without MCC, relative weight 0.8692), 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 1 more, in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites) 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.
