What This Code Means
B02.7 is the ICD-10-CM diagnosis code for disseminated zoster. Disseminated zoster is a widespread shingles infection that has spread to multiple areas of the body beyond the typical single nerve distribution. This is a more serious form of shingles that affects larger portions of the skin and potentially internal organs. B02.7 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).
B02.7 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Disseminated zoster (B02.7) indicates shingles has spread systemically; verify documentation specifies dissemination rather than localized zoster to ensure accurate code selection.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B02.7 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Disseminated zoster (B02.7) indicates shingles has spread systemically; verify documentation specifies dissemination rather than localized zoster to ensure accurate code selection
- •When coding B02.7, check for associated complications (such as post-herpetic neuralgia, ocular involvement, or encephalitis) and code those separately with appropriate B02.x subcodes or other ICD-10-CM codes
