Physicians often expand their practices by accepting Medicare. This insurance program has a lower fee schedule than many other insurers, but it tends to pay promptly and consistently. However, the decision to accept Medicare isn't a one-time decision that never needs to be revisited once it's made. Instead, it requires regular examination to verify these claims are being processed properly, thus ensuring the practice is paid appropriately. In addition to maintaining its revenue stream, a practice that accepts Medicare must be able to pass regular Medicare audits.
