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.
