What This Code Means
B02.9 is the ICD-10-CM diagnosis code for zoster without complications. Shingles (herpes zoster) without any significant complications affecting other organs or systems. B02.9 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).
B02.9 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.
This is the default code when zoster is uncomplicated; do not use if any complications are documented.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for B02.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
