Mental Health CPT Codes: The Definitive Guide [2020]

CPT (Current Procedural Terminology) is a standardized medical codeset maintained by the AMA.  CPT codes are five digit numeric codes describing everything from surgery to radiology to psychotherapy.

For therapists that are on managed care panels or provide superbills to their clients, knowing your CPT codes is paramount to getting paid in full and avoiding insurance audits.

The amount insurance companies will reimburse depends on a number of different factors (professional credentials, geographic location, etc.), but using the correct CPT Code and add-on code(s) to express the exact service is an important part to the whole process and in ultimately determining your payment!

Errors, accidental or otherwise, will directly impact insurance company’s payment of services.  If you need help with making sure your billing and coding is error-free, our mental health billing service can help.

CPT Coding for Therapy

CPT coding for psychotherapy doesn’t have to be difficult!  There are an overwhelming amount of total CPT Codes (~8,000), however only 24 are specifically designated for psychotherapy and other mental health services.

To make matters even simpler, nearly all therapists will regularly use an even smaller subset of these 24.

CPT is a large and dynamic code set that changes year to year, but the psychotherapy codes seldom change.

The most recent change for psychotherapy codes took place in 2019, then 2013, and previously 1998.

To ensure your coding is current and up to date, consider using a billing service instead of having to remember all the codes.

Behavioral Health CPT Add-On Codes

A CPT Add-on Code is a code describing a service performed in in conjunction with a primary service. Many of these add-on codes are associated with a specific CPT Code or a small set of CPT Codes and cannot be used otherwise.

For instance, the behavioral health CPT Code for interactive complexity (+90785) can be used for a diagnostic (90791, 90792) or a normal psychotherapy session (90832, 90834, 90837) but not a crisis psychotherapy session (90839).

CMS 1500 with CPT Code 99355

Add-on Codes are identified by a + sign in front of the number, i.e. +90840 is an add-on code for extra time in the case of crisis psychotherapy.

On CMS 1500 forms CPT Add-on codes are simply added on a new line.

Add-on codes are extremely important to use in order to most accurately describe the services being rendered and to ensure your services are maximized per session.

We help the mental health providers that work with us in our billing service do all of this for every appointment.

Mental Health Evaluation & Management (E/M) Codes

There are also E/M (evaluation & management) in conjunction with psychotherapy, used by authorized prescribers, psychiatrists, and MDs.

Coding E/M is trickier, harder to document and more vulnerable to audit but usually results in greater reimbursement.

There’s also a series of E/M codes that are used without the psychotherapy component.

For more in-depth coverage on E/M coding for psychotherapy there are some good free webinars released by AACAP on E/M CPT Codes.

  • Add-on CPT Code +90833 – E/M code for 30 minutes of psychiatry (used with 90832).
  • Add-on CPT Code +90836 – E/M code for 45 minutes of psychiatry (used with 90834).
  • Add-on CPT Code +90838 – E/M code for 60 minutes of psychotherapy (used with 90837).

Key Points

  • Psychotherapy must be at least 16 minutes.
  • Time is very important and should be rounded to the nearest CPT Code.
  • Outpatient vs. Inpatient is not important.
  • E/M codes can only be used by prescribers (MD, DO, APN, PA).

Interactive Complexity (+90785):  Criteria and How to Bill

+90785 is one of the new add-on codes in the most recent CPT update in 2013.

This code is used as an umbrella add-on code and can be used for four different criteria. The most common scenarios usually involve children, although this is not necessarily always the case.

Common Examples of Interactive Complexity:

  • The use of play equipment with young children.
  • Interpreters/translators.
  • Involvement of parents with discordant views that complicate the treatment plan.
  • Report of abuse/neglect.

Interactive complexity can be used in conjunction with the primary CPT Codes for diagnostics, psychotherapy, or group therapy and cannot be used for couple/family therapy or crisis codes.

+90785, can be used with: 90791, 90792, 90832, 90833, 90834, 90836, 90837, 90838, 90853.

Am I Being Underpaid? Was I Paid the Right Amount?

Here’s typical rates depending on the therapist’s credentials:

Typical Reimbursements by Type of Therapist

Type of TherapistReimbursement/Session
Social Workers~$55-60
Marriage Family Therapists~$60-65
Counselors~$60-65
Psychologists~$70-80

These rates can vary significantly therapist to therapist but are good benchmarks for comparison.

How about CPT Codes? How do they affect the rate of reimbursement? This is a difficult and complex calculation, depending on the level of education, location, and license. The AMA has created a code search feature on their website that shows payment based off CPT Code and location.

This information is somewhat incomplete and is based off medicare payments and does not specify a number of other important factors. However, this tool is still very useful to compare the relative value CPT Codes against one another.

Private insurance will be correlated with some deviation from these numbers.

Downcoding Claims

Downcoding (including less services on the claim than actually provided) will usually mean you get paid less, while upcoding (including more services on the claim than actually provided) can get you in trouble with your managed care panels.

It’s also important to note that it might be tempting to maximize your CPT codes to earn higher reimbursements.

This is highly recommended against and can get you flagged, audited and removed from insurance panels. Even if this is your biller’s error, the therapist is the one who ultimately bears the responsibility and will be the one penalized.
Here’s a video guide we did of this article!

Distilled Guide to Mental Health CPT Codes

If you are just starting out or just beginning to deal with managed care, keep it simple.

CPT Codes appear far more complex from the outside looking in. Make a quick cheatsheet.

Don’t worry about memorizing all the CPT Codes (there’s alot!) or even all of the mental health ones. You will likely just use just a few individual codes.

Memorize the relevant codes and use google or other references to find the correct CPT codes for more unique scenarios.

Call to verify eligibility and benefits and make sure those codes will be approved with that client’s coverage.

And if all of that sounds like too much trouble, offload the work to us.  You won’t have to know one CPT code from another to get your billing paid in full.
