Zoster without complications

This code represents a herpes zoster infection (shingles) that presents without any associated complications. It indicates the presence of the characteristic vesicular rash, pain, and neurological symptoms typical of shingles, but without secondary bacterial infection, ophthalmic involvement, disseminated disease, or other specified complications.

Use this code when documentation clearly states a diagnosis of herpes zoster and explicitly or implicitly indicates the absence of complications. This is appropriate for typical, uncomplicated cases of shingles affecting a single dermatome. Supporting documentation would include physician notes detailing the rash, pain, and a lack of mention of any secondary issues.

• Do not use this code if any specific complication of zoster is documented; instead, select a more specific code from the B02 category.
• Consider sequencing this code as the primary diagnosis when the zoster is the reason for the encounter.
• Ensure the medical record explicitly rules out or does not mention complications to justify using the "without complications" designation.
