Is there any instance where more than one unit of 90791 can be billed on the same day? We have a client who came in for a walk in evaluation through our outpatient department then had a separate evaluation through our drug and alcohol program. Administration thinks we should be able to bill for both services as they were through separate programs. They were performed by the same therapist and will be billed under the same tax ID. If we can bill for both what modifier would you suggest to avoid a duplicate denial?
Thank you!
