Clarifying CPT for Psychotherapy and TOS in Medical Billing – Let’s Share Insights!

[precisionhub]

Hi everyone,

I wanted to start a conversation around two crucial but sometimes confusing topics in our billing process: CPT for psychotherapy and the use of TOS (Type of Service) in medical billing.

When billing for psychotherapy, we rely heavily on CPT codes like 90832, 90834, and 90837 to represent 30, 45, and 60-minute sessions. But sometimes, even when our coding seems correct, claims still get rejected—and I’ve found that TOS coding can sometimes be the hidden issue.

TOS in medical billing, or Type of Service, is the code used to categorize the nature of the care being billed. If it doesn’t align with the CPT or place of service (like POS 11), the claim can get flagged or denied. This especially affects mental health services where documentation needs to be precise.

So I wanted to ask:

• How do you ensure your TOS code aligns with your psychotherapy CPT codes?
• Have you faced claim denials that were traced back to mismatched or incorrect TOS entries?
• Are there any best practices your team follows for clean submissions when it comes to therapy billing?

Would love to hear what you all are seeing on your end—especially those dealing with high claim volumes or hybrid service models.

Thanks in advance for sharing!
