Yes. Since January 1, 2024, licensed marriage and family therapists and mental health counselors, including LPCs, can enroll in Medicare Part B and bill under their own NPI. They enroll through PECOS on the CMS-855I, must accept assignment and are paid 75% of the psychologist rate, about $125.25 for a 60-minute 90837 in 2026.
The 75% rate is not what costs new Medicare counselors money; the first 60 days of setup is. In our claim audit, 22% of first-month Medicare claims from newly enrolled MFTs and MHCs were denied, mostly for enrollment dates and reassignments that were not finished. Get the approval letter in hand before the first Medicare session and most of that loss never happens.
Methodology:Luxen figures come from four datasets: the Luxen claim audit (61,400 claims audited, Jan 2025 to Jun 2026), including 7,200 behavioral health claims; Luxen billing reviews (410 practice billing reviews, Jan 2025 to Jun 2026); Luxen client data (38 client practices, Jan 2024 to Jun 2026); and the Luxen Practice Manager Survey 2026 (286 practice managers, March 2026). Rules, rates and enrollment steps are cited to CMS, eCFR, HHS and MAC sources.
Yes. A licensed marriage and family therapist or mental health counselor can bill Medicare directly if they hold a master’s or doctoral degree that qualifies for licensure, a current state license or certification, and at least 2 years or 3,000 hours of post-degree supervised clinical experience. Those definitions sit in 42 CFR 410.53 and 410.54, which CMS wrote to carry out Section 4121 of the Consolidated Appropriations Act, 2023. The benefit covers services on or after January 1, 2024, and nothing before that date is payable.
The license title does not matter as long as the state license covers the work. LPCs, LMHCs, LCPCs and LPCCs all enroll as mental health counselors. Addiction counselors and alcohol and drug counselors who meet every MHC requirement can enroll as MHCs too. CMS said more than 400,000 clinicians became eligible, and NBCC reported that over 38,000 counselors had enrolled by mid-June 2024.
Pre-licensed associates, interns and clinicians still collecting supervised hours cannot enroll. Medicare also does not cover services furnished incident to an MFT’s or MHC’s own services, so an associate’s session cannot go out under the supervising LMFT’s or LPC’s NPI. The one route is incident to a physician, clinical psychologist, nurse practitioner, physician assistant or clinical nurse specialist. Since 2024, behavioral health services by auxiliary personnel can be billed that way under general supervision, where state law and scope allow it.
Enrollment takes six steps and carries no application fee. CMS says clean online applications are processed within 15 calendar days and paper applications within 30.
Your effective date is the later of the date the MAC received an application it later approved or the date you first saw patients at that location (42 CFR 424.520). Under 424.521 you can bill for services in the 30 days before that date when circumstances kept you from enrolling earlier. Older sessions are not payable, and a clinician who is neither enrolled nor opted out cannot collect cash from the patient for them either. File before your first Medicare session, not after it.
Enrollment is also state specific. You need a separate 855I in each state where you practice, and you must be licensed where the patient is located. In our billing reviews, credentialing lapses delayed payment for 1 in 12 providers added in the prior year, and a lapsed re-credentialing held payments for a median of 47 days. Revalidation dates belong on a calendar, and our Medicare and payer credentialing team files and tracks them.
MFTs and MHCs can bill Medicare for the diagnosis and treatment of mental illness within their state scope of practice, on an 837P claim under their own rendering NPI. In practice that covers:
Services that need a medical license sit outside the benefit: 90792 with medical services, E/M visits, medication management and, in general, psychological testing 96130 to 96139. MFTs and MHCs also cannot bill for partial hospitalization or intensive outpatient services furnished by a hospital outpatient department or community mental health center. Their services to a skilled nursing facility resident are excluded from consolidated billing, so they bill Part B directly.
Only as treatment for a diagnosed patient. Medicare covers family psychotherapy when its primary purpose is the patient’s treatment, so 90847 with a spouse in the room works when the patient has a mental health diagnosis and the note ties the session to that plan. Relationship counseling with no identified patient and only a Z-code does not fit a benefit written for the diagnosis and treatment of mental illness.
Psychotherapy codes are time codes, and reviewers check the note against the clock. In our claim audit, 18% of 90837 claims had documented session time under 53 minutes, across 7,200 behavioral health claims. Each of those belonged on 90834, and a post-payment review takes the difference back.
Medicare pays MFTs and MHCs 75% of the clinical psychologist amount under the Physician Fee Schedule, then pays 80% of that allowed amount once the patient meets the $283 Part B deductible for 2026. The 2026 conversion factor is $33.40, and CMS exempted time-based behavioral health codes from the 2.5% efficiency cut it applied to many other services. National per-code amounts are on our therapist billing rates for 2026 page; your MAC locality moves them up or down.
Take one LPC in a locality near the national average who sees 8 intakes, 64 sixty-minute sessions, 16 forty-five-minute sessions and 8 family sessions a month.
| Code | Visits | Allowed each (75%) | Monthly allowed |
|---|---|---|---|
| 90791 | 8 | $130.01 | $1,040.08 |
| 90837 | 64 | $125.25 | $8,016.00 |
| 90834 | 16 | $85.43 | $1,366.88 |
| 90847 | 8 | $82.16 | $657.28 |
| Total | 96 | $11,080.24 |
Medicare pays 80% of $11,080.24, or $8,864.19, and the patients owe $2,216.05 in coinsurance. Many of them carry Medigap or Medicaid that picks up that 20%, so the secondary claim is part of the job.
The 60-minute sessions carry the practice: about $8,016 of the month, against $1,367 from 45-minute sessions, $1,040 from intakes and $657 from family sessions.
Days in AR decide when that money arrives. In our billing reviews, solo therapists carried a median 41 days in AR, against 29 for group practices. At about $369.34 of allowed charges a day, 41 days holds roughly $15,143 in unpaid claims and 29 days holds $10,711. The $4,432 gap is cash a solo clinician waits on every month.
Yes. MFT and MHC services are paid on an assignment-only basis, so you accept the Medicare allowed amount as payment in full and collect only the deductible and 20% coinsurance from the patient. There is no non-participating option with a higher limiting charge like the one physicians have.
If you do not want Medicare at all, you still have a filing decision to make. A clinician who is neither enrolled nor opted out must submit claims for covered services and cannot simply charge a Medicare patient cash. To see Medicare patients privately, file an opt-out affidavit with your MAC and sign a private contract with each patient. 42 CFR 405.400 lists MFTs and MHCs among the practitioners who can opt out. An opt-out lasts two years and renews automatically unless you cancel in writing at least 30 days before the next period starts.
Medicare Advantage plans cover the same Part B benefit but pay only in-network clinicians outside emergencies, so you contract with each plan separately. Since 2025, CMS network adequacy standards include an Outpatient Behavioral Health category that counts MFTs and MHCs, which gives plans a reason to add you. Check coverage at every visit: eligibility and coverage errors caused 24% of denials in our claim audit, and a patient who moved from Original Medicare to an Advantage plan in January is the classic case. Our eligibility verification runs that check before the session.
For dual-eligible patients, Medicare pays first and Medicaid second. Several state Medicaid programs, Texas among them, told LPCs and LMFTs to enroll in Medicare because Medicaid denies claims that skip the Medicare step. Enroll in both, bill Medicare first and let the crossover claim carry the coinsurance.
Medicare pays for mental health telehealth in the patient’s home permanently, including audio-only when the patient cannot or will not use video. The Consolidated Appropriations Act, 2026 pushed back the rule that required an in-person visit within six months of the first telehealth session, and HHS says it does not apply through December 31, 2027.
Coding the setting is where telehealth claims leak. Telehealth place-of-service and modifier errors caused 15% of behavioral health telehealth denials in our claim audit, and audio-only visits were billed with video modifiers on 6% of telehealth claims. Payer-by-payer rules are on our telehealth billing page.
Most first-year denials for newly enrolled MFTs and MHCs come from setup, not clinical documentation. In our claim audit, 22% of first-month Medicare claims from newly enrolled MFTs and MHCs were denied, most for a missing PTAN, a date of service before the effective date or an unfinished reassignment.
Across those denials, enrollment and reassignment gaps made up 27%, session time below the code threshold 19%, telehealth place of service or modifier errors 16%, Advantage members billed to Original Medicare 14%, deductible and eligibility issues 13% and family codes without a patient-focused note 11%.
Our denial and AR recovery work starts with those unworked claims.
Bill in-house if you have one or two clinicians, a clean enrollment and someone who reads every remittance each week; outsource when Medicare volume grows and follow-up slips. Fully loaded in-house billing cost 7.9% of collections for practices under $2M, across 96 practices that shared payroll data, in our billing reviews. Outsourced full-service medical billing typically runs 3% to 6% of collections.
On the worked example, collecting all $11,080.24 a month, 3% to 6% is $332.41 to $664.81, against $875.34 at 7.9% in-house. Time matters too: practice managers estimated 11 staff hours a week on insurance calls and portal checks in our 2026 survey, and for a solo clinician those hours come out of sessions.
Either way the steps are the same: eligibility, enrollment, coding, claims, remittances and appeals. See how they fit together in behavioral health revenue cycle management, or book a free billing review and we will check your Medicare enrollment and first claims.

Solo clinicians enroll on their own 855I, bill under their own PTAN and carry every step themselves: eligibility, claims, remittances and the secondary claim for coinsurance. The cost shows up in cash flow. Solo therapists run longer AR than groups, and one missed revalidation stops all Medicare income at once because there is no second clinician billing. Keep the approval letter, PTAN, effective date and revalidation due date in one place, and check Medicare Advantage status before every first visit of the year.
Each licensed MFT or MHC still needs an individual 855I, with benefits reassigned to the group on that same application. The group’s PTAN does not change. Groups lose money when a new hire starts seeing Medicare patients before the reassignment is approved, or when an associate’s sessions go out under a licensed colleague. Commercial panels move slower: new clinicians waited a median 96 days to go in-network with commercial payers in our billing reviews, so Medicare is often the first payer a new counselor can bill.
A counselor inside a primary care practice has two billing paths. The MFT or MHC can enroll and bill their own psychotherapy and G0323 behavioral health integration, or work as auxiliary personnel whose services are billed incident to the physician or NP under general supervision. The first path pays 75% of the psychologist amount under the counselor’s NPI; the second pays at the supervising practitioner’s rate but ties the service to that provider’s plan of care. Our primary care billing page covers the physician side.
Since January 1, 2024, MFTs and MHCs count as RHC and FQHC practitioners, so a qualifying mental health visit with one of them is paid at the clinic’s encounter rate rather than the fee schedule. Mental health telehealth visits from these clinics use their own billing rules. Rendering provider errors are the common failure: visits billed under the wrong rendering provider caused 8% of RHC and FQHC denials in our claim audit. See FQHC billing for encounter rate rules.
Licensed addiction counselors and alcohol and drug counselors who meet the MHC degree, supervised-hours and licensure rules can enroll as mental health counselors with specialty code E2 and bill their own outpatient services. Counselors without a qualifying master’s degree cannot. Services inside an opioid treatment program bundle, a partial hospitalization program or an intensive outpatient program billed by a hospital or community mental health center are paid to that program, not to the counselor. More on program billing at substance abuse billing.
The hospice interdisciplinary team must now include at least one social worker, MFT or MHC, so hospices can staff that role with a counselor. Counseling for a hospice patient’s terminal illness is covered inside the hospice per diem, not billed to Part B by the counselor. Hospice revenue losses come from paperwork timing instead: late notices of election or admission caused 11% of hospice and home health payment losses in our billing reviews.
Physical therapists cannot bill psychotherapy, but a pain or rehab practice can add an enrolled counselor who bills health behavior assessment and intervention codes 96156 to 96171 for chronic pain, adherence or coping. Those codes require a physical health diagnosis as the focus and are billed under the counselor’s own NPI at 75% of the psychologist amount. The therapy side keeps its own rules, such as the KX modifier and the 8-minute rule.
Yes, but each Medicare Advantage plan runs its own network. You enroll in Original Medicare first, then apply to each Advantage plan you want to join. Out of network, most HMO plans pay nothing outside emergencies, while PPO plans may pay at a lower rate. Always verify which plan the patient has before the first session of each year.
Yes. CMS requires a separate CMS-855I enrollment in each state where you practice, and you must be licensed in the state where the patient is located during the session. Counseling compact privileges are accepted where the compact is in effect. Telehealth clients in another state therefore mean another license and another Medicare enrollment.
No. CMS does not charge individual MFTs or mental health counselors an application fee, and they are screened in the limited risk category, so there is no site visit or fingerprinting. Clean applications filed online through PECOS are processed within 15 calendar days and paper applications within 30 calendar days.
Only for a short window. Your effective date is the later of your filing date or the date you started seeing patients, and you can bill for the 30 days before that date when circumstances kept you from enrolling earlier. Sessions older than that are not payable, so file the CMS-855I before the first Medicare appointment.
No. Medicare requires a master’s or doctoral degree that qualifies for licensure, a current state license or certification and 2 years or 3,000 hours of post-degree supervised clinical experience. Addiction counselors who meet those rules can enroll as mental health counselors, but bachelor’s-level or certificate-only counselors cannot enroll or bill Medicare under their own NPI.
Use the ICD-10-CM mental health diagnosis you are treating, usually from the F01 to F99 range. Medicare pays MFT and counselor services for the diagnosis and treatment of mental illness, so a claim with only a Z-code for relationship problems is likely to deny. Health behavior codes are the exception and point to a physical health diagnosis.
