90853 Authorization and Limits
Not all plans consider group therapy as a routine outpatient mental health service and will not cover 90853 billing without prior authorization.
Ensure you obtain authorization to bill for group therapy for that client during your eligibility and benefits verification phone call. Ask about limits to services as well.
If you’re struggling to find out exactly which services will be covered, when conducting your call ask specifically if CPT Code 90853 is covered. We do this as part of our billing service.
90853 Billing and Coding Recommendations
You should genuinely not exceed 10 clients per group session nor should sessions exceed a single CPT code per day.
If you do want to conduct an individual therapy session with a client you saw during group, use the same day billing modifier appropriate to that insurance company. Best to call ahead about this as well.
Each client’s diagnosis will be specific to them even if the topic of conversation is about one specific topic. Use specified diagnoses when billing your group therapy claims.
