Think about how insurance works in other areas:
- Home insurance is tied to a specific property
- Auto insurance is tied to a specific vehicle
- Medical insurance is tied to a specific person with a diagnosis
Therapy billing works the same way.
When a therapist submits a claim, they’re not just documenting the service—they are identifying who received treatment, what mental health condition is being treated, and how that treatment is medically necessary.
This is done using a standardized medical billing form called the CMS-1500, which is required across healthcare settings.
Here’s the key issue:
That form only allows for one identified patient.
So from the insurance company’s perspective, therapy is never for “the relationship.” It is always for one individual’s diagnosed condition.
How It Can Be Covered (But With Limitations)
In some cases, insurance may reimburse sessions that include a partner—but only under very specific conditions:
- One identified patient
One person must be evaluated individually. This includes a full clinical intake assessing symptoms, history, trauma, and functioning. - A diagnosable mental health condition
The therapist must determine that this individual meets criteria for a condition such as depression, anxiety, PTSD, etc. - A treatment plan for that individual
The plan is designed to treat that person’s symptoms. Sometimes, involving a partner in sessions may be considered clinically helpful—but only as it relates to that individual’s care.
Important Clarification
The couple does not sign the treatment plan—only the identified individual does, because they are the one receiving care from the insurance company’s perspective.
This highlights a core limitation of the system:
Even when both partners are present, insurance is still treating the session as individual medical care—not relationship-focused work.
Why This Feels Confusing (and Sometimes Frustrating)
Many people have had therapy experiences where this wasn’t clearly explained. Some are even told by their insurance benefits department that “couples therapy is covered.”
But when claims are actually submitted, the outcome can look very different.
Why does this happen?
Because benefits representatives provide general coverage information, not final determinations. Approval happens later—when the claim is processed—based on medical necessity, diagnosis, documentation, and how the service is billed.
Here’s what remains true across plans:
- Every insurance company—including Aetna, Blue Cross Blue Shield, and UnitedHealthcare—requires a mental health diagnosis
- Every claim is submitted using the CMS-1500, which allows only one identified patient
- Billing for couples therapy without an identified patient and diagnosis may violate insurance policy
Many clients who come into my practice are surprised to learn this—often because no one has taken the time to clearly explain how the system actually works.
What This Means for My Practice
Because of these limitations, I do not provide couples counseling through insurance.
Couples work is focused on the relationship as the client—not one person’s diagnosis. In order to do that ethically and effectively, sessions are offered on a self-pay basis
