Can 0592T be billed without 0591T?

Answered by Angel Reyes, MCHES®Last verified: November 5, 2026

Short answer

Unresolved. Addendum B lists 0592T with the "ZZZ" global indicator used for add-on codes, mirroring its crosswalk 99489. The rule doesn't explain how a follow-up billed without 0591T will process; wait for MAC guidance.

See 0592T follow-up sessions. We'll update the change log when contractors publish guidance.
