What does the modifier -24 signify in CPT coding?

The modifier -24 is used in CPT coding to indicate that an evaluation and management (E/M) service was provided by the same physician during a postoperative period and that this service is unrelated to the original procedure. This is crucial because it allows physicians to bill for an E/M service that addresses a new condition or issue that arises during the postoperative period, without it being considered part of the global surgical package.

When a patient is in the postoperative period following a surgical procedure, certain services related to the surgery are bundled into the global fee. However, if an unrelated problem occurs and necessitates a separate E/M service, the modifier -24 clarifies that the service is distinct from the surgical procedure, ensuring proper reimbursement. This modifier emphasizes the thoroughness in clinical documentation, allowing for a clear distinction between routine postoperative care and additional services rendered for unrelated issues.
