Question 1

What are CPT codes for mental health?

Accepted Answer

CPT (Current Procedural Terminology) codes are standardized five-digit codes developed by the AMA that describe the medical services a provider delivers. Mental health CPT codes specifically cover psychotherapy sessions, psychiatric evaluations, psychological testing, crisis intervention, and related behavioral health services. They are required on every insurance claim to receive reimbursement.

Question 2

What are the most common psychotherapy CPT codes?

Accepted Answer

The three most commonly used psychotherapy codes are 90832 (30 minutes of individual psychotherapy, for sessions lasting 16–37 minutes), 90834 (45 minutes, for sessions lasting 38–52 minutes), and 90837 (60 minutes, for sessions lasting 53 minutes or longer). Other frequently used codes include 90846 and 90847 for family psychotherapy and 90853 for group psychotherapy.

Question 3

Are telehealth therapy sessions billed the same as in-person visits?

Accepted Answer

Yes. According to CMS, telehealth visits use the same CPT codes and are reimbursed at the same rates as in-person sessions. The difference is that you add modifier 95 (or GT) to indicate a real-time telecommunication interaction and use Place of Service code 02 instead of 11.

Question 4

What CPT code should I use for an initial psychiatric evaluation?

Accepted Answer

Use 90791 for a psychiatric diagnostic evaluation without medical services, or 90792 for a psychiatric diagnostic evaluation with medical services. Depending on the complexity and time involved, you may also bill an E/M code (such as 99202–99205 for new patients) alongside the evaluation code.

Question 5

What is the difference between CPT codes and ICD codes?

Accepted Answer

ICD codes describe the patient's diagnosis — the reason treatment is necessary (such as F41.9 for anxiety disorder). CPT codes describe the specific service provided (such as 90834 for a 45-minute psychotherapy session). Both are required on insurance claims: ICD codes justify medical necessity, and CPT codes specify what services were delivered.

Question 6

What CPT codes are most commonly missed by mental health providers?

Accepted Answer

Many providers overlook add-on codes like 90785 (interactive complexity) and 90840 (crisis psychotherapy add-on). Missing these reduces reimbursement and underreports services. Reviewing the latest AMA CPT updates regularly ensures all eligible services are captured accurately.

Question 7

How often are mental health CPT codes updated?

Accepted Answer

The American Medical Association updates CPT codes annually, typically each January. These updates can redefine time-based codes, introduce new procedures, or revise descriptions for greater accuracy. Behavioral health professionals should review changes every year to ensure compliance and reimbursement accuracy.

Question 8

What’s the best way to document medical necessity for psychotherapy sessions?

Accepted Answer

Documentation should include the diagnosis, treatment goals, patient progress, and clinical justification for ongoing therapy. Insurers often require evidence that sessions address functional impairment. Linking ICD codes directly to CPT procedures reinforces medical necessity in the billing record.

Question 9

Can multiple CPT codes be billed during the same therapy session?

Accepted Answer

Yes, but only when distinct services are provided and separately documented. For instance, you may bill both a psychotherapy and an E/M code if you evaluate medication during the same encounter. Clearly note separate times and purposes for each service in the clinical record.

Question 10

Are there CPT codes specific to group telehealth therapy?

Accepted Answer

Group telehealth psychotherapy uses CPT code 90853 with a telehealth modifier (95 or GT). The Place of Service code should be “02” to indicate telecommunication delivery. Billing requirements mirror in-person sessions, but documentation must state that the session occurred via secure video conferencing.
