Q. Will Medicare contractors accept the CPT consultation codes when Medicare is the secondary payer?
A. Medicare will also no longer recognize the CPT consultation codes for purposes of determining Medicare secondary payments (MSP). In MSP cases, providers must bill an appropriate E/M code for the E/M services previously reported and paid using the CPT consultation codes. If the primary payer for the service continues to recognize CPT consultation codes for payment, providers billing for these services may either:
• Bill the primary payer an E/M code that is appropriate for the service, and then report the amount actually paid by the primary payer, along with the same E/M code, to Medicare for determination of whether a payment is due; or
• Bill the primary payer using a CPT consultation code that is appropriate for the service, and then report the amount actually paid by the primary payer, along with an E/M code that is appropriate for the service, to Medicare for determination of whether a payment is due.
Q. Can a provider provide an advance beneficiary notice (ABN) to the beneficiary and then bill his or her charge for the consultation after the consultation is billed and denied by Medicare?
A. No, when a CPT consultation code is reported to Medicare, the claim is not denied. Instead, the claim is returned to the provider for a different CPT code because Medicare recognizes another code for payment of E/M services that may be described by CPT consultation codes. Once the claim is resubmitted to report an appropriate, payable E/M code (other than a CPT consultation code) for a medically reasonable and necessary E/M service, the beneficiary can only be billed any applicable Medicare deductible and coinsurance amounts that apply to the covered E/M service.
