Mental health credentialing is the process of getting an NPI, building a complete CAQH ProView profile, enrolling with Medicare and Medicaid, and applying to commercial plans, so each payer verifies your license and adds you to its network before you bill it as in-network.
For therapists the process changed a lot in 2024. Since 1 January 2024, licensed marriage and family therapists (MFTs) and mental health counselors (MHCs), including most LPCs, LMHCs and LCPCs, can enroll in Medicare Part B and bill it directly. That means many counselors and family therapists now have one more payer to set up, with its own forms, effective-date rules and revalidation cycle.
This guide walks through the full mental health credentialing process in the order that avoids rework: identifiers first, then CAQH, then government payers, then commercial panels, then ongoing maintenance. It covers LCSWs, LPCs and LMHCs, LMFTs, psychologists and group practices.
Credentialing is one part of the revenue cycle. Our mental health billing guide explains how it connects to eligibility checks, coding, claims and denials.
Key Takeaways
- Credentialing (verifying your qualifications), contracting (signing the payer agreement) and enrollment (loading you in the payer’s system) are separate steps; you are not in-network until all three are done.
- Since 1 January 2024, MFTs and MHCs can enroll in Medicare under section 4121 of the Consolidated Appropriations Act, 2023. CMS will not grant an effective date earlier than 1 January 2024.
- Medicare enrollment runs through PECOS or the paper CMS-855I. CMS may allow billing up to 30 days before your effective date, so file before you start seeing Medicare patients.
- CAQH ProView asks providers to re-attest every 120 days. A lapsed attestation can stall applications and recredentialing at plans that use CAQH.
- Individuals use a Type 1 NPI. A group practice, or a therapist who bills through an LLC or corporation, also needs a Type 2 NPI.
Credentialing vs Contracting vs Enrollment
Practices often use these words as if they mean the same thing. Payers do not, and mixing them up is how a therapist ends up seeing patients before the plan can pay for the visits.
| Step | What happens | What you receive |
|---|---|---|
| Credentialing | The payer verifies your license, education, supervised experience, malpractice coverage, work history and sanctions | Approval from the plan’s credentialing committee |
| Contracting | You and the payer sign a participation agreement with a fee schedule | A signed contract and an effective date |
| Enrollment / loading | The payer links your NPI, tax ID and service locations in its claims system | Claims that process as in-network |
| Medicare enrollment | CMS and its Medicare Administrative Contractor (MAC) approve your billing privileges | A PTAN and an effective date |

Which Mental Health Providers Can Credential With Which Payers
Your license type decides which payers can credential you and under which Medicare benefit category. Commercial and Medicaid rules vary by plan and state, so always check each payer’s provider manual.
| License | Medicare category | Notes |
|---|---|---|
| LCSW / LICSW | Clinical social worker | Enrolled in Medicare long before 2024; must hold the state clinical social work license |
| LPC / LMHC / LCPC | Mental health counselor (MHC) | Eligible since 1 January 2024; taxonomy 101YM0800X on the MHC enrollment |
| LMFT | Marriage and family therapist (MFT) | Eligible since 1 January 2024; taxonomy 106H00000X |
| Addiction counselor | May enroll as an MHC | Only if the counselor meets every MHC requirement, even if the state license uses a different title |
| Psychologist (PhD, PsyD) | Clinical psychologist | Long-standing Medicare provider type |
| Pre-licensed associate | Not separately enrollable | Commercial and Medicaid rules on supervised associates vary widely; ask each payer in writing |
Medicare Requirements for MFTs and MHCs
The CMS FAQ for marriage and family therapists and mental health counselors lists three requirements for each provider type:
- A master’s or doctoral degree that qualifies you for licensure or certification as an MFT, or as an MHC, clinical professional counselor or professional counselor, under the law of the state where you practice.
- At least 2 years or 3,000 hours of post-master’s clinical supervised experience in marriage and family therapy or mental health counseling.
- A current license or certification as an MFT or MHC in the state where you furnish services.
Medicare pays MFT and MHC services at 80% of the lesser of the actual charge or 75% of the amount paid to clinical psychologists under the Physician Fee Schedule. Medicare does not pay claims for dates of service before 1 January 2024.
The Mental Health Credentialing Process, Step by Step
- Get and check your NPI. Apply for a Type 1 (individual) NPI in NPPES. If you bill through a group, an LLC or a corporation, the entity needs its own Type 2 NPI. Make sure your NPPES taxonomy, practice address and mailing address match your license and every application you file.
- Set up the practice entity. Confirm the legal business name and tax ID on your IRS letter. Use the same name and TIN on your W-9, CAQH profile, Medicare application and payer contracts. A mismatch is one of the most common reasons applications are returned.
- Build your CAQH ProView profile. Enter your education, license, supervised experience, work history, practice locations, hours and malpractice policy. Upload your license, liability certificate and any DEA or board documents. Then grant access to each plan you are applying to and attest.
- Enroll in Medicare, if you will see Medicare patients. Apply through PECOS or with the paper CMS-855I. Include EFT information (CMS-588 or its PECOS equivalent) and, if you bill under your own number, the participation agreement. If you join a group, reassign your benefits to it so it can bill for your services.
- Enroll in Medicaid and its managed care plans. Complete your state Medicaid enrollment first, then credential with each Medicaid managed care organization you want to work with. State enrollment alone does not make you in-network with the plans. See Medicaid managed care credentialing for how that second layer works.
- Apply to commercial plans. Check whether each plan’s behavioral health network is run by the plan itself or by a separate behavioral health company, and whether the network is open in your area for your license type. Submit the plan’s application and point it to your CAQH profile.
- Review and sign contracts. Read the fee schedule for the codes you bill most, such as 90791, 90834 and 90837, plus timely filing limits, telehealth terms and termination clauses. Record the effective date the payer gives you.
- Confirm the load before booking patients. Call or check the payer portal to confirm your NPI, TIN and location are active. Then run a test eligibility check on a real member before scheduling as in-network.
Do not schedule in-network sessions on the date you submit an application. Approval, contract signature and system loading come later. Sessions before the effective date usually pay as out-of-network or not at all.
Medicare Enrollment Details Therapists Miss
Effective date. For physicians and non-physician practitioners, CMS sets the effective date as the later of the date the MAC receives a processable application or the date you first furnished services at the new location.
30-day look-back. CMS may allow a retrospective billing date up to 30 days before the effective date. Services delivered earlier than that window are generally not payable, so submit your application before your first Medicare session.
PTAN. Once approved, your MAC issues a Provider Transaction Access Number. You use it for MAC portal access and enrollment updates, while claims carry your NPI. Our guide to the PTAN in medical billing explains how it is used.
Revalidation. Medicare requires most practitioners to revalidate their enrollment every five years, and CMS or your MAC tells you the due date. A missed revalidation can deactivate your billing privileges.

CAQH ProView: Getting It Right
CAQH ProView is free for providers, and many commercial and Medicaid plans use it to collect credentialing data instead of their own long forms. Plans see only the profile you authorize them to see, and only after you attest that it is accurate.
- Re-attest every 120 days, even if nothing has changed.
- Upload a new malpractice certificate and license before the old ones expire.
- Explain any gap in work history longer than the plan’s threshold; many plans ask about gaps of six months or more.
- Keep practice locations, hours and telehealth status current, because plans use them for their directories.
- Authorize every plan you apply to, or the plan cannot see your profile.
Re-attestation is a recurring task that is easy to miss during a busy month. Our step-by-step CAQH re-attestation guide shows what to review each cycle.
How Long Mental Health Credentialing Takes
There is no single timeline. Medicare processing depends on your MAC and on whether your application is complete. Commercial plans add their own verification, committee review and contract steps. Plans with closed behavioral health networks may not accept your application at all until a spot opens. Overall, plan for several months from first application to the first in-network payment, and start well before a new clinician’s first day.
What slows things down is usually in your control: an unsigned page, a CAQH profile that is out of date, an address that does not match NPPES, or a slow reply to a payer’s request for information. Our list of common credentialing mistakes that delay payments covers the ones we see most often.
Worked Example: An LMFT Opening a Solo Practice
A hypothetical LMFT leaves a group practice to open a solo telehealth and in-office practice as a single-member LLC. She plans to take Medicare, her state Medicaid program and three commercial plans.
| Item | What she does | Why |
|---|---|---|
| NPI | Keeps her existing Type 1 NPI and gets a Type 2 NPI for the LLC | Her NPI never changes; the LLC bills under its own NPI and TIN |
| NPPES | Updates her practice address and confirms taxonomy 106H00000X | Addresses and taxonomy must match her applications |
| CAQH | Adds the new location, uploads her new malpractice certificate, authorizes all three plans and re-attests | The plans pull her data from CAQH |
| Medicare | Enrolls the LLC, updates her own enrollment and reassigns her benefits to the LLC in PECOS | The LLC can then bill for her Medicare services |
| Commercial | Adds the new TIN and location to her existing contracts, or applies again where the plan requires it | A new TIN is often treated as a new contract |
| Go-live | Books in-network patients only after each payer confirms her effective date | Avoids sessions that pay out of network |
The same name changes and location moves apply to established clinicians. Our guide to updating provider credentials with payers covers those changes.
After You Are Credentialed
Getting in-network is the start, not the end. Plans recredential providers on a cycle, often every three years, and they expect your CAQH profile, license and malpractice coverage to stay current between cycles. Keep one calendar for license renewals, CAQH attestations, malpractice renewals, Medicare revalidation and each plan’s recredentialing letters.
Once you are active, the next risks are coding and claims. Use our mental health CPT codes guide to choose the right psychotherapy codes, follow how to bill for mental health therapy for each claim, and see how to reduce behavioral health billing denials for the denials a credentialing gap can cause. If you offer virtual care, check the telehealth mental health CPT codes and POS rules too.
Do not let a credentialing gap hide in your A/R. Denials for an inactive or unknown provider often look like ordinary denials. Our guide to signs of mental health revenue leakage shows how to spot them.

Frequently Asked Questions
Can LPCs and LMFTs bill Medicare?
Yes. Since 1 January 2024, licensed marriage and family therapists and mental health counselors, including most LPCs, LMHCs and LCPCs, can enroll in Medicare Part B if they hold a qualifying master’s or doctoral degree, have at least 2 years or 3,000 hours of post-master’s supervised clinical experience, and are licensed in the state where they practice.
How often do I need to re-attest my CAQH profile?
CAQH ProView asks providers to re-attest every 120 days. Re-attest even when nothing has changed, and update expiring documents such as your license and malpractice certificate before they lapse.
Do I need a Type 1 or Type 2 NPI as a therapist?
Every individual therapist needs a Type 1 NPI. A group practice, or a therapist who bills through an LLC or corporation, also needs a Type 2 NPI for the organization. A sole proprietor uses only a Type 1 NPI.
Can I bill sessions I provided before my credentialing was approved?
For Medicare, CMS may allow billing up to 30 days before your effective date, but not earlier. Commercial plans set their own effective dates and many will not pay in-network for sessions before that date, so confirm the date in writing before scheduling.
How long does mental health credentialing take?
It varies by payer, state and how complete your application is. Plan for several months from first application to first in-network payment, and longer where a plan’s behavioral health network is closed.
