Psychology Billing Services for Psychologists and Groups
Medtransic bills insurance and handles credentialing for psychologists, from solo practices to groups. We bill therapy sessions and psychological testing, and we get testing approved before the work starts when the plan requires it. We work inside SimplePractice, TherapyNotes and the other systems psychologists use. Billing is 4-8% of what we collect for you. Credentialing is $150 per application, per provider, and usually takes 60 to 90 days with each payer. There is no long-term contract.

Where psychology practices lose money
Therapy is the steady part; testing is where most of the money, and most denials, sit.
- Testing done before it was approved
- Many commercial plans require prior authorization for testing, for specific services and units. Testing without approval, or past the approved units, is usually not paid.
- Testing billed in the wrong parts
- Administration and scoring is billed in 30-minute units; evaluation, including the report and feedback, by the hour. Time recorded in the wrong part goes unpaid.
- Interns and postdocs billed as if licensed
- Medicare does not pay for services by interns or postdocs, even under supervision. Some commercial plans and Medicaid programs allow supervised billing, so it is checked payer by payer.
- Out-of-network clients with no usable superbill
- Self-pay clients often claim from their insurer with a superbill. If it lacks the details the insurer needs, they are not reimbursed and the practice hears about it.

Medicare rules psychologists should know in 2026
These are current as of October 2026.

- Clinical psychologists bill under their own number. Medicare pays the full fee schedule rate only if they accept assignment.

- Unless the primary care doctor referred, offer to consult them and document the patient's answer.
- 03
Telehealth made permanent

- 04
Testing incident to

- 05
Prescribing psychologists
- What it means
- Eight states as of May 2026: Colorado, Idaho, Illinois, Iowa, Louisiana, New Mexico, Utah and Vermont.
Getting each psychologist in network
The same payer process as other clinicians, with a few points specific to psychology.
- 1
License and NPI in order
An independent-level license where clients are located, your NPI, and usually an organization NPI if you practice as a group or LLC.
- 2
CAQH profile complete and attested
Most commercial payers read your CAQH Provider Data Portal profile, free for clinicians; we complete it and re-attest every 120 days.
- 3
Medicare, if you take it
Clinical psychologists enroll online in PECOS, separately from commercial payers, and we file it alongside your other applications.
- 4
Applications filed and tracked
We follow each application until approval and record each effective date in your client portal.
- 5
PSYPACT for telehealth across states
PSYPACT authorization (APIT) lets you offer telepsychology to clients in other member states, but payers still need to credential you.
PSYPACT: you must be physically in your home state while you practice. More than 40 states have joined, plus DC; Alaska and Iowa passed laws in 2026, and Iowa's takes effect July 1, 2027. Check the PSYPACT map for the states currently in effect.
Payer notes for psychology
Testing approvals are by service and unit
Bill only what was approved, or ask for more before testing goes over.
Behavioral health networks run separately
The company on the card is not always the one that credentials you or pays the claim. We check before the first appointment.
Medicaid varies by plan
Coverage for testing and therapy, and who can enroll, varies by state and managed care plan. We check the plan, not just the state.
Your client portal, included
Your EHR shows what you billed. Your portal shows what we are doing about it.
Your EHR or practice management system runs your practice, but it does not show you our work. The Medtransic HIPAA Compliant Portal does: every claim and its current stage, the denials we are working, your A/R by age, each payer application and its in-network date, and the documents we still need from you. It is the same record our team works from, and it comes with every client account.
- Did that claim get paid?
- Every claim with its stage and amount, the denials we're working, and your receivables by age.
- Where is my application with Aetna?
- Each payer application shows its stage, its history, and the date you can start seeing that payer's patients.
- What do you still need from me?
- One list of the documents we're waiting on. Upload once, and it reaches every payer that asked for it.

When we are not the right fit
- If your practice is entirely self-pay and you do not want to join panels, you may only need a superbill process.
- If your testing is mostly forensic or school-funded work outside health insurance, most of it will not run through insurance billing.
Questions psychology practices ask us
How long does it take to get a psychologist in network?
In our experience it usually takes 60 to 90 days with each payer. Payers set their own timelines (Evernorth, for example, says up to 90 calendar days). A complete CAQH profile keeps the application moving.
What does it cost to get a psychologist in network?
Medtransic charges $150 per application, per provider, with no long-term contract. The CAQH profile itself is free for clinicians.
Do you bill psychological testing?
Yes. We get testing approved first where the plan requires it, track the approved units, and bill administration and evaluation as the two separate parts payers expect.
Can you credential a postdoctoral fellow?
Insurers generally credential only fully licensed psychologists, and Medicare does not pay for services by interns or postdocs even under supervision. Some commercial plans and Medicaid programs allow supervised billing, so we check payer by payer.
How much does psychology billing cost?
Billing is 4-8% of what we collect for you. The consultation before you sign is free.
