Can Modifier 25 Be Appended to G0439?

Modifier 25 is not needed when billed with G0438/G0439 and an injection. This modifier is not even an option for those HCPCS.

Can 99213 and G0439 be billed together?

Medicare does discourage this and says there is too much 'crossover' between these two preventive services. We usually see a 99213 or 99214 with a G0438 or G0439 to represent the problem management outside the AWV. If you bill G0438/G0439 and a 99397, recognize that Medicare does not cover the 99397.

When should you use modifier 25?

Modifier -25 is used to indicate an Evaluation and Management (E/M) service on the same day when another service was provided to the patient by the same physician.
