Getting a handle on CPT codes can feel like one more thing on your already full plate, but it’s an essential part of running a mental health practice. These codes help you communicate with insurance companies about the services you provide, so you get paid without unnecessary delays. Let’s walk through the CPT codes you’ll likely use most often, with a few tips to make it easier to manage.

90791: Psychiatric Diagnostic Evaluation

This is your go-to code for initial assessments. Whether you’re meeting a new client for the first time or doing a comprehensive re-evaluation after some time away, this is the code that captures the intake process. You’ll be gathering information, assessing their mental health, and setting up a plan for treatment. Keep in mind, no medical services are billed under this code—it’s all about understanding your client’s mental health needs and mapping out next steps.

Time range: Typically 60 minutes, but it can vary based on the complexity of the evaluation.

90837: Individual Therapy, 60 minutes

If you’re doing a full, hour-long therapy session, you’ll use CPT code 90837. It’s perfect for in-depth work, giving you and your client the time to dive deeper into ongoing issues. Some clients need that extra time to process, reflect, and move through more complex concerns, so 90837 is a great option for those sessions where 45 minutes just wouldn’t cut it.

Time range: 53 minutes or longer

90834: Individual Therapy, 45 minutes

The middle child of therapy codes, 90834 is the most commonly used for individual sessions lasting about 45 minutes. It’s just the right balance between being long enough to get meaningful work done but short enough to fit a busy day. Insurance companies tend to like this one too, so you’ll probably use it often in your practice.

Time range: 38 to 52 minutes.

90832: Individual Therapy, 30 minutes

Sometimes a shorter session is all you need. If you’re doing a focused, 30-minute session, 90832 is your code. These briefer appointments are great for quick check-ins, follow-ups, or clients who prefer shorter sessions. Just make sure you’ve got a plan going in because those 30 minutes will fly by.

Time range: 16 to 37 minutes.

90847: Family or Couples Therapy with the Client Present

Family dynamics can play a big role in a client’s mental health. When you’re working with a client and their family members or partner in the same session, 90847 is the CPT code to use. This might involve anything from working through communication issues to resolving long-standing conflicts—whatever it takes to help the family function better together.

Time range: Typically 50 minutes, but it can vary.

90846: Family Therapy without the Client Present

Sometimes, the work happens without the client in the room. Maybe their family members need to strategize or learn how best to support the client’s mental health journey. In these cases, 90846 is the code you’ll use for family therapy where the client isn’t present. It’s an important tool for getting everyone on the same page.

Time range: Typically 50 minutes, but can vary based on the session.

It’s all about matching the session type, length, and structure to the right code. With practice, it’ll become second nature—just like a well-timed therapeutic breakthrough.
