Launching Dec 2026 · New Mexico Medical Psilocybin Program

Insurance billing for psychedelic-assisted therapy clinics.

Join the waitlist
Starting with a handful of founding clinics in New Mexico.
Our mission
Psychedelic therapy can't just be for the rich. This treatment needs to be covered by regular insurance.
Downstream exists to do the unglamorous part: getting this care paid for by the insurance people already have.

Why Downstream Billing

1

Built for this care model

Prep sessions, dosing days, and integration visits all bill differently, and some of it can't go to insurance at all. We code to the legal guidance written for psilocybin therapy in New Mexico, and we can show our work on every claim.

2

Never taken insurance? That's normal here.

Most clinicians in this field have never been paneled with a payer. Credentialing is months of forms and follow-up calls, so we start before your doors open. You send us one packet of documents and we take it from there: Medicaid enrollment, CAQH, plan applications, contracting.

3

You send us visit records. We do everything else.

Someone at your front desk uploads visit records to our portal. We check each patient's coverage, tell you in plain English if anything is missing, send the claims to the insurance company, track the payments, and follow up on anything that gets denied.

4

A person approves every claim

The software drafts claims. It doesn't send them. A billing specialist looks at every claim, prior auth, and appeal before it goes anywhere, and the system refuses outright to bill things that shouldn't be billed.

We've heard every reason not to.

Most of them are fair. Here's what we tell people, with the actual numbers.

"It's such a pain!"

It is. That's the business we're in. Your front desk uploads visit records; everything after that is our problem.

"My payments get denied."

Most denials happen because something was wrong before the claim ever went out. We catch that at intake. When a payer denies anyway, we appeal instead of writing it off.

"Reimbursement rates are terrible."

They're better than this field assumes. NM Medicaid now pays behavioral health at 150% of Medicare or better, and a single prep session pays $203 to $228. The insured part of a course comes to $840 to $1,027 per patient at today's provisional rates.

"Cash-pay clinics charge $3,200–4,000."

That's the problem. $3,000–4,000 in cash, upfront, limits this treatment to people who can write the check. Until FDA approval, the dosing day won't be covered — patients pay it directly or the state Equity Fund does. But everything else can be paid for with the insurance patients already have, so their cost drops from thousands to a known fee plus copays.

What insurance actually pays

PayerScreeningPrep session (×2)Integration session (×2, 60 min)Insurance pays*
NM Medicaid (Turquoise Care)$133$228$218$1,027
BCBS New Mexico$145$213$152$876
Presbyterian Health Plan$138$203$148$840

* One screening, two prep sessions, and two 60-minute integration sessions, billed with standard E/M and psychotherapy codes. These are provisional fee-schedule rates for illustration. Your actual rates get set in your payer contracts during credentialing. NM Medicaid figures reflect the state's 150%-of-Medicare minimum that took effect January 2025. The dosing day itself, administration and monitoring both, can't be billed to insurance before FDA approval. We route it to self-pay or the state Equity Fund and track it so it never ends up on a claim. If approval comes and coverage opens, turning monitoring billing on is a settings change, worth another $796 to $887 per dosing day at these rates.

For clinics

Insurance revenue stacks on top of your cash model. Dosing days stay direct pay, and everything around them gets billed. Three credentialed clinicians doing twelve courses a month bring in roughly $10,000 to $12,000 a month that a cash-only clinic never sees, and it grows as your panel does. You pay a flat credentialing fee up front, then a percentage of what we actually collect.

For patients

Screening, prep, and integration go through the insurance a patient already has, Medicaid or commercial, the same way regular therapy does. They pay their normal copays. The dosing day is the one direct cost, and they know the exact amount before their first visit. And for anything paid out of pocket, we provide a coded superbill so patients can seek out-of-network reimbursement from their own plan.

Most of the people who need this care can't pay cash for it. Insurance is how we make psychedelics work — for everyone.
