Summary
A previous notice incorrectly listed CPT code 90857 for group psychotherapy changes, but this code is not covered. The actual affected codes are 90853 and 90849 for group psychotherapy services.
Action Required
Immediately: Billing team must verify that CPT code 90857 is not being used for group psychotherapy billing as it is not covered. Ensure only CPT codes 90853 and 90849 are used for group psychotherapy services. Update billing system rules and encounter forms to reflect correct covered codes.
