About B10.82
B10.82 is the ICD-10-CM diagnosis code for human herpesvirus 7 infection. It belongs to category B10 (other human herpesviruses), block B10 (other human herpesviruses) 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 B10.8 (other human herpesvirus infection), B10.82 is specifically for human herpesvirus 7 infection. Related codes cover human herpesvirus 6 infection (B10.81) and other human herpesvirus infection (B10.89).
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) and DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), 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 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 058.82 (human herpesvirus 7 infection).
