B02.7

What This Code Means

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.

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
