Traditional Medicare does not cover a "preventive wellness" visit. This is/has been a standard policy.
30.6.2 - Billing for Medically Necessary Visit on Same Occasion as Preventive Medicine Service. (Rev. 1, 10-01-03)
See Chapter 18 for payment for covered preventive services.
When a physician furnishes a Medicare beneficiary a covered visit at the same place and on the same occasion as a noncovered preventive medicine service (CPT
codes 99381-99397), consider the covered visit to be provided in lieu of a part of the preventive medicine service of equal value to the visit. A preventive medicine service (CPT codes 99381-99397)
is a noncovered service. The physician may charge the beneficiary, as a charge for the noncovered remainder of the service, the amount by which the physician's current established charge for the preventive medicine service exceeds his/her current established charge for the covered visit. Pay for the covered visit based on the lesser of the fee schedule amount or the physician's actual charge for the visit. The physician is not required to give the beneficiary written advance notice of noncoverage of the part of the visit that constitutes a routine preventive visit. However, the physician is responsible for notifying the patient in advance of his/her liability for the charges for services that are not medically necessary to treat the illness or injury.
