How to Order Labs in a Cash-Pay Telepsychiatry Practice

Ordering labs for a telehealth psychiatry patient is a real logistics problem, because Quest and LabCorp both routinely decline to open standard provider accounts for practices that see patients only by video, citing internal policy rather than any written rule. Psychiatrists we've watched build cash-pay and telehealth practices solve it with the same handful of methods: keep applying for a direct account while working around the wait, hand the patient a coded requisition they can walk into almost any lab with, route functional and specialty panels through a dedicated ordering platform, or send the patient to a patient-pay lab service that skips provider accounts entirely. None of these require your EHR to have built-in lab ordering, which is fortunate, since almost none of them do.

This post walks through each method in the order most new telepsych practices try them, plus the ICD-10 coding detail that keeps a patient from a surprise $500 bill at the draw station.

1. Apply for a direct Quest or LabCorp account anyway

Start here even though the odds are worse for telehealth-only practices than the vendor sites suggest. Quest's provider-enrollment page asks for your practice's contact and billing information plus each ordering clinician's name, NPI, and license number, and Quest says a confirmed account typically arrives with a starter supply kit. In practice, telepsych founders have reported two separate failure modes: LabCorp declining new accounts outright for practices with no in-person component, citing internal policy with no stated timeline for when it lifts, and Quest rejecting applications over projected patient volume, in one case turning down an estimate of 15 patients a week. Neither company publishes a formal telehealth exclusion, and neither confirms a minimum volume, so treat a rejection as a data point about that reviewer on that day rather than a permanent verdict.

Two things improve your odds. If your practice has any in-person capacity at all, even occasional, list it; both companies appear to weigh it in the account review. And apply through the direct provider-account link rather than a general contact form. More than one applicant lost weeks to an unanswered contact-form submission before finding the actual enrollment page. Budget several weeks either way, and don't let a launch date depend on the account being live.

2. Order without an account: the requisition method

While you wait, or if the account never comes through, a simple lab requisition works at nearly every commercial draw site with no account on your end at all. Build a one-page order on your practice letterhead, or your EHR's plainest note template, with:

• Patient full name and date of birth
• The tests ordered, with their ICD-10 justification codes (more on getting this right below)
• Your name, NPI, and state license number
• Where results should go: a fax number, or a clear instruction that the patient will forward them to you

Give the patient the requisition to bring in person rather than faxing it to the lab ahead of time. Faxed advance orders have a habit of not being on file when the patient actually walks in, while a printed or emailed copy the patient hands over at the front desk works reliably. If you want results faxed back automatically going forward, call the lab's provider-services line and ask to have your fax number added to their system. Some practices report the wait runs to months, so don't count on it for your first few orders.

3. Route functional and specialty panels through a dedicated ordering platform

Standard chemistries and CBCs aren't the only labs psychiatrists order. Functional and integrative workups, organic acids, GI panels, salivary cortisol, pharmacogenomic testing, run through separate platforms built for exactly this, and they don't carry the same telehealth-account friction as Quest or LabCorp. Rupa Health built a catalog of these specialty labs for cash-pay ordering; Fullscript acquired Rupa in October 2024 and is folding its lab catalog into Fullscript's own ordering system through 2026, so expect the login screen to change even if the workflow doesn't. Evexia Diagnostics offers a similar path into specialty lab networks, and adds a physician-network fee for non-physician ordering that's waived once you're a licensed prescriber ordering under your own name.

These platforms are worth setting up even if you also land a standard Quest or LabCorp account, since they cover tests neither major lab runs, or runs at a price a cash-pay patient will actually accept.

4. Send the patient straight to a patient-pay lab, no account needed

For a standard panel, the account-free option is to let the patient buy the test directly. Ulta Lab Tests sells common blood work at self-pay prices that run up to 90 percent below list, routes the specimen through Quest's own lab network, and requires no referring-provider account at all: the patient orders online, gets a lab requisition, and walks into any of more than 2,000 CLIA-certified draw sites. You still write the clinical order and interpret the result; you just skip the account fight entirely for the tests this covers.

For patients who can't reach a draw site, whether that's mobility, transportation, or plain telehealth geography, a mobile phlebotomy service that draws blood at the patient's home is worth keeping on your referral list. Most metro areas have at least one option; build the relationship once and it becomes a standing answer for any patient who needs it.

5. Loop in the patient's PCP when you genuinely can't order it yourself

Some orders sit outside what a solo psychiatric practice can reasonably run on its own: imaging, an EKG before starting a stimulant, or anything your state routes through an in-network referral. The reliable pattern is a short letter naming the specific test or referral you need, with your clinical reasoning attached, sent through the patient's primary care provider rather than attempted cold. For something as routine as a pre-stimulant EKG, a one-page coded order the patient hand-carries to their PCP's office is usually enough.

6. Code the order so your patient doesn't get a surprise bill

This is where most of the actual damage happens, and it's fixable. Vitamin D and folate panels are the two tests most often named in surprise bills of $500 to $1,000, and the cause is almost always the diagnosis code on the order, not the test itself.

"Order the panel you can clinically justify, and code it to the symptom or the medication you're monitoring," says Juan Rodriguez, MD, who reviewed this guide. "A screening code is how a $40 draw becomes a $400 surprise."

Medicare's own coverage rules for lab claims draw a hard line between screening and diagnostic use: a claim carrying only a screening code, like Z13.9 (encounter for screening, unspecified) or Z13.39 (screening for mental health and behavioral disorders), reads as "no medical reason established yet," and Medicare's lab coverage policy won't pay a claim on that code alone. Private payers commonly apply the same logic even though the underlying rule is a Medicare policy, so treat it as the default assumption rather than a Medicare-only quirk, and confirm current requirements with your billing service, since payer rules shift.

The fix is to stack a reason code that actually explains why you're ordering the test:

Pair one of these with the patient's actual psychiatric diagnosis on every order. A screening code standing alone, with nothing else on the claim, is the one combination to avoid. And tell the patient, before the tech draws blood, to ask what each test costs and whether it's covered based on the codes on the order, so a denial surfaces as a choice at the counter instead of a bill three weeks later:

"Can you tell me the price for each of these tests before you draw my blood, and let me know if any of them aren't covered so I can decide whether to skip it?"

Print that line on the requisition itself if you routinely see it help. This is coding guidance rather than billing or legal advice; a coder or your billing service can confirm the current rule for a specific payer.

The recap

• Apply for a direct Quest or LabCorp account even though telepsych practices get rejected or delayed. Treat a no as reversible rather than final.
• Build a one-page requisition template with your NPI, license number, and a results-routing instruction, and hand it to the patient rather than faxing it ahead.
• Set up Rupa Health, moving into Fullscript through 2026, or Evexia for functional and specialty panels standard labs don't run.
• Keep a patient-pay option like Ulta Lab Tests and a mobile phlebotomy contact on hand for patients who need an account-free or at-home path.
• Route anything outside your scope, like imaging or a pre-stimulant EKG, through the patient's PCP with a coded order letter.
• Stack a real reason code (drug monitoring, symptom, or routine exam) with the psychiatric diagnosis on every order, and never rely on a screening code alone.

None of this changes once you sort out which EHR to build the rest of your practice on; lab ordering sits outside every platform in that comparison, so the workaround above is the job regardless of what you chart in. The same telehealth-only address that trips up a lab application shows up again when you register for DEA and state prescribing purposes, and the requisition template here pairs naturally with the rest of your intake paperwork so a patient gets both in one packet. If you're also navigating multistate prescribing rules for the same telehealth launch, our guide to controlled substances over telehealth covers the parallel patchwork on that side.
