Does insurance cover sex therapy? Codes, superbills, and real costs
The honest version: when sex therapy is billable, which CPT codes are used, how out-of-network reimbursement actually works, and the exact questions to ask your plan before you book.
Written and clinically reviewed by Vanessa Cushing, LPC, NCC, MS — AASECT-Certified Sex Therapist, licensed in Virginia, DC, Maryland & Florida.
The short answer
Sometimes. Sex therapy provided by a licensed clinician bills under standard psychotherapy codes — 90791 for the intake, 90837 for a 60-minute session — when there is a covered mental health diagnosis. Many specialists are out-of-network and provide superbills for partial reimbursement instead.
Why coverage is inconsistent
Insurance does not reimburse 'sex therapy' as a category. It reimburses psychotherapy delivered by a licensed clinician for a diagnosable condition. When a sexual concern maps to a billable diagnosis — a sexual dysfunction diagnosis, an adjustment disorder, PTSD, an anxiety or depressive disorder — the sessions are billable psychotherapy like any other.
The gaps show up in three places. Couples work is often excluded because many plans only cover treatment for an identified patient. Concerns that do not meet criteria for any diagnosis — a desire mismatch between two people with no disorder — may not be billable at all. And a great many certified sex therapists are deliberately out-of-network, because panel rates do not support the specialization.
The codes you will see
A superbill is simply an itemized receipt containing these codes, the diagnosis code, the dates of service, the fee paid, and your clinician's license and NPI numbers. You submit it to your insurer yourself and they reimburse according to your out-of-network benefit.
| Code | What it is |
|---|---|
| 90791 | Diagnostic intake evaluation — your first session |
| 90834 | Individual psychotherapy, 45 minutes |
| 90837 | Individual psychotherapy, 60 minutes |
| 90847 | Family or couples psychotherapy with the patient present |
| 90846 | Family or couples psychotherapy without the patient present |
How out-of-network reimbursement actually works
Two numbers determine what you get back: your out-of-network deductible, and your coinsurance percentage applied to what your plan calls the allowed amount. The allowed amount is the insurer's own valuation of the session — often meaningfully lower than what a specialist charges — and your reimbursement is a percentage of that number, not of your actual fee.
The practical implication: on a $250 session with a 60 percent coinsurance rate and a $200 allowed amount, you are reimbursed $120 once the deductible is met, not $150. Ask for the allowed amount for 90837 in your ZIP code and you can estimate your real per-session cost before you commit.
Exactly what to ask your insurer
- Do I have out-of-network outpatient mental health benefits?
- What is my out-of-network deductible, and how much of it have I met this year?
- What is my coinsurance percentage after the deductible?
- What is the allowed amount for CPT 90837 in my ZIP code?
- Do I need pre-authorization for outpatient psychotherapy?
- Is there a session limit per calendar year?
- Is CPT 90847 (couples/family therapy) covered under my plan?
Other ways to reduce cost
- HSA and FSA funds cover psychotherapy, including out-of-network sessions. This is the most commonly missed option.
- Ask about sliding scale directly. Many practices reserve a small number of reduced-fee slots and simply do not advertise them.
- Ask about session spacing. Biweekly sessions with disciplined at-home practice are often as effective as weekly for maintenance-phase work, and halve the monthly cost.
- Consider a shorter, focused course. A well-defined single-issue concern treated in 8 to 10 sessions costs far less than open-ended therapy, and your therapist should be willing to scope it that way.
One caution about diagnosis
Billing insurance requires a mental health diagnosis in your permanent record. For most people this is a non-issue. If you hold a security clearance, work in aviation, or have specific concerns about a diagnostic record, discuss it with your therapist before the first claim goes out — paying privately is a legitimate choice and does not change the quality of care.
Frequently asked questions
- Does insurance cover sex therapy?
- It can. Insurers reimburse psychotherapy by a licensed clinician for a covered diagnosis, and sex therapy bills under the same codes as any other psychotherapy. Coverage fails when the concern does not meet criteria for a diagnosis, when the plan excludes couples therapy, or when the therapist is out-of-network.
- What CPT code is used for sex therapy?
- There is no sex-therapy-specific code. Clinicians bill 90791 for the diagnostic intake, 90834 or 90837 for 45- or 60-minute individual sessions, and 90847 for couples sessions with the patient present.
- What is a superbill and how do I use it?
- A superbill is an itemized receipt listing the CPT codes, diagnosis code, dates of service, fee paid, and your clinician's license and NPI numbers. You pay the therapist directly, then submit the superbill to your insurer through their member portal for out-of-network reimbursement.
- How much does sex therapy cost out of pocket?
- In the US, AASECT-certified sex therapists generally charge $175 to $400 per session depending on region and specialization. A focused course of 8 to 12 sessions is common. HSA and FSA funds can be used, and some practices offer a limited number of sliding-scale slots.
- Is couples sex therapy covered by insurance?
- Less often than individual therapy. Many plans reimburse only treatment directed at a diagnosed individual, so couples sessions billed under 90847 are frequently excluded or limited. Verify coverage for 90847 specifically before assuming it is included.
