Final answer:
The office should have billed the employer's workers' compensation as it should have been the primary payer for an on-the-job injury. Receiving a Medicare payment was inappropriate and needs to be refunded so the workers' compensation insurance can be billed correctly. The correct option is C.
Step-by-step explanation:
If a 66-year-old patient was injured while performing a task for their employer and subsequently treated for a fractured wrist, the correct action would not be for Medicare to pay for the urgent care visit. This situation would typically fall under a worker's compensation case, because the injury occurred in the scope of the individual's employment.
Since workers' compensation is responsible for covering injuries that occur on the job, the urgent care office initially should have billed the employer's workers' compensation insurance.
The reimbursement by Medicare in this case was not appropriate because workers' compensation should have been the primary payer. If the office received payment from Medicare, they would need to refund Medicare and bill the workers' compensation accordingly. The correct option is C.
