Couples Therapy Billing: CPT Codes and Insurance Coverage

Couples therapy billing is one of the most misunderstood areas of mental health billing. The CPT codes are clear, but the coverage picture is complicated — most insurance plans do not cover couples therapy as a standalone service. Here is what you need to know to bill correctly and set accurate expectations with clients.

The Two CPT Codes for Couples and Family Therapy

Two CPT codes cover conjoint (multi-person) therapy sessions:

• 90847 — Family psychotherapy with patient present. Used when an identified patient (the person with the covered diagnosis) is present in the session along with their partner or family member(s). This is the most commonly applicable code for couples therapy when one partner has a covered mental health diagnosis.
• 90846 — Family psychotherapy without patient present. Used when only the partner or family members attend — for example, a session coaching a spouse on supporting a partner with depression, without the patient present.

These codes are flat-rate (not time-based like individual psychotherapy codes). They cover the full session regardless of whether it runs 45 or 75 minutes.

Why Insurance Usually Does Not Cover Couples Therapy

Here is the critical issue: most insurance plans do not cover relationship problems as a covered diagnosis. For insurance to pay for a session, there must be anidentified patient — one person with a billable ICD-10 mental health diagnosis — and the therapy must be medically necessary to treat that person's condition. A session focused purely on relationship conflict, communication, or intimacy, with no underlying individual mental health diagnosis, will typically be denied as a covered benefit.

The ICD-10 does include relational codes:

• Z63.0 — Problems in relationship with spouse or partner.
• Z63.5 — Disruption of family by separation and divorce.

However, these Z-codes are not covered mental health diagnoses for most insurance plans. They are supplementary codes only. Billing couples therapy under these codes alone will almost always result in denial.

When Couples Therapy Is Covered

Coverage is possible when all of the following are true:

• One partner has a covered mental health diagnosis (e.g., F32 major depressive disorder, F43.10 PTSD, F41.1 generalized anxiety).
• The couples session is clinically necessary to treat that individual's condition (e.g., relationship conflict is a primary stressor maintaining the depression).
• CPT 90847 is billed, with the covered patient listed as the patient on the claim.
• Your session notes clearly document how the conjoint session addresses the identified patient's treatment goals.

The "Identified Patient" Problem

Some therapists attempt to bill couples therapy by designating one partner as the patient. This is acceptable when clinically accurate — but billing insurance for what is really a relationship-focused service by assigning a mental health diagnosis to one partner solely for billing purposes crosses into fraudulent billing. The diagnosis must reflect a genuine clinical assessment, and the treatment must be oriented toward that person's mental health condition.

Out-of-Pocket and Out-of-Network Couples Therapy

Given the coverage limitations, many couples therapists operate on a private-pay basis. Couples who do have one partner with a covered diagnosis can still submit superbills using CPT 90847 for out-of-network reimbursement. Superbilled generates superbills for conjoint therapy sessions with the correct codes, so clients can pursue reimbursement where their benefits allow it.
