What This Code Means
B08.03 is the ICD-10-CM diagnosis code for pseudocowpox [milker's node]. Pseudocowpox, also called milker's node, is a viral infection that affects dairy workers and farmers who handle infected cattle. B08.03 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering viral infections characterized by skin and mucous membrane lesions (b00-b09).
B08.03 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Document occupational exposure history when present.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for B08.03 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
