Which of the following does Medicare not accept?

Medicare does not accept physical status modifiers, which are designated for use primarily in the anesthesia section of the CPT coding system. These modifiers indicate the patient's physical condition prior to undergoing anesthesia and are typically used in the context of anesthesia billing.

The global surgical package, evaluation and management codes, and preventive service codes are all accepted by Medicare. The global surgical package includes pre-operative, operative, and post-operative care related to surgical procedures and is utilized in billing for surgical services. Evaluation and management codes are critical for documenting patient encounters and facilitating appropriate reimbursement for a variety of medical services, while preventive service codes are relevant for services aimed at disease prevention and health promotion, which are highly emphasized in Medicare policies.

Thus, knowing that Medicare does not accept physical status modifiers is essential for accurate coding and billing practices within the Medicare system.
