CPT Code 90834

For therapists, understanding CPT code 90834 is not just about paperwork—it’s about getting paid accurately and ensuring compliance with healthcare regulations. This code specifically represents 45-minute individual psychotherapy sessions, and it’s a vital component in the billing process. 

Without precise coding, you risk underpayment, delays, or even claim denials. So, let’s decode CPT code 90834 and explore why it’s a crucial piece of the puzzle every therapist needs to master.

What Is CPT Code 90834?

CPT code 90834 is used to bill for individual psychotherapy sessions lasting approximately 45 minutes in an outpatient setting. According to the Centers for Medicare Services (CMS), this code covers sessions that are insight-oriented, behavior-modifying, supportive, and interactive. 

It’s important for therapists to know that this code should not be used when the therapy involves teaching grooming skills, recreational activities like dance or art therapy, or when working with clients who have severe intellectual disabilities or dementia—those scenarios require different CPT codes. 

Correctly identifying when to use CPT 90834 ensures proper billing and maximizes reimbursement, making it a critical tool for every therapist’s billing toolkit.

CPT Code 90834 Time Range

CPT code 90834 is specifically designed for individual psychotherapy sessions that typically last 45 minutes. However, the code also covers sessions ranging from 38 to 52 minutes, providing some flexibility in billing for slightly shorter or longer sessions. 

For therapy sessions that fall below 38 minutes, the appropriate code is 90832, which covers sessions lasting from 16 to 37 minutes. On the other hand, sessions extending beyond 53 minutes are billed under CPT code 90837.
