Billing CPT Codes 93880, 93306, and 76881: Modifier Usage & Date of Service Rules

CPT code 93880 for psychotherapy (45 minutes) can be billed with a modifier to indicate the specific type of psychotherapy provided. For example, modifier 90 may be used to indicate individual psychotherapy, modifier 91 to indicate family psychotherapy, and modifier 92 for group psychotherapy.

CPT code 93306 cannot be billed with a procedure code on the same date of service. So if 76881 or 93880 was submitted on the same day, 93306 could not be billed.

CPT code 76881 for ultrasound guidance for vascular access cannot be billed with a modifier.
