Mental Health Billing Services For Providers

Medix Revenue Group offers specialized Mental Health Billing Services tailored for behavioral health professionals, therapists, psychologists, psychiatrists, and mental health clinics. Our mission is simple: to streamline your revenue cycle, eliminate administrative burden, and boost your financial performance.

Why Mental Health Billing Requires a Specialized Approach

Real-time eligibility checks and prior authorization support
Clean claims submission and faster reimbursement
Compliance with mental health billing regulations (HIPAA, CMS, state guidelines)

We help avoid costly denials and delays that often plague mental health providers.

Mental Health CPT and ICD-10 Codes We Bill

Mental health claims are rarely denied because a service wasn’t covered. They’re denied because a time threshold wasn’t documented, an add-on code was paired incorrectly, or a diagnosis was too vague to prove medical necessity. Our billers work from the clinical note to the claim, so the code on the claim matches what actually happened in the session.

CPT Codes Billing Table

CPT Code	What It Covers	Common Billing Pitfall
90791 / 90792	Psychiatric diagnostic evaluation. 90792 includes medical services and is for prescribers.	Billing 90792 for a non-prescriber, or repeating an evaluation more often than the payer allows.
90832 / 90834 / 90837	Individual psychotherapy at 30, 45, and 60 minutes (16-37, 38-52, and 53+ minutes of face-to-face time).	Billing 90837 for a shorter session or without documented start and stop times. 90837 draws more payer scrutiny than 90834.
90846 / 90847 / 90853	Family therapy without the patient (90846), family therapy with the patient (90847), and group psychotherapy (90853).	Missing documentation of who attended, or billing group sessions without a separate note for each patient.
90785	Interactive complexity add-on, used with certain evaluation and psychotherapy codes.	Adding it without documenting the specific communication barrier, or pairing it with crisis codes or an E/M service alone.
90833 / 90836 / 90838	Psychotherapy add-on to an E/M visit at 30, 45, and 60 minutes, for prescribers.	Counting the same minutes twice, or choosing the E/M level by time instead of medical decision-making when an add-on is billed.
96130 / 96136 (and add-ons 96131 / 96137)	Psychological testing evaluation services and test administration and scoring by a clinician.	Missing prior authorization, unit errors on time-based codes, and billing technician-administered testing under clinician codes.
99202-99205 / 99212-99215	New and established patient E/M visits, common in psychiatry and medication management.	Documentation that doesn't support the E/M level billed, or an E/M and therapy note that can't be told apart.

Telehealth Mental Health Billing

Telehealth is now a standard part of behavioral health care, but the billing rules still change by payer, state, and patient location. A claim that is correct for one payer can be denied by another.

Modifiers and place of service

Modifier 95 identifies a synchronous audio-video telemedicine service. Modifier GT is an older modifier that some payers still require. Some payers want one, some want both, and some rely on place of service alone.
POS 02 means telehealth provided somewhere other than the patient's home. POS 10 means telehealth provided in the patient's home. Using the wrong one can cause a denial or a payment at the wrong rate.

We keep a payer-by-payer reference so the right combination goes on each claim.

Medicare and commercial payers differ

Medicare vs Commercial and Medicaid Telehealth Table

	Medicare	Commercial and Medicaid plans
Home-based mental health telehealth	Covered, including from the patient's home. The in-person visit requirement is delayed through December 31, 2027. Starting January 1, 2028, most patients will need an in-person visit within six months before their first mental health telehealth service, and one every 12 months after. Patients who start on or before December 31, 2027 only need the annual visit. Last reviewed September 30, 2026. Source: Telehealth.HHS.gov	Set by each plan; some follow Medicare, others have their own rules.
Modifiers and POS	Follows CMS guidance, which has changed over time.	Varies widely by payer and often by plan.
Payment rates	Set by the fee schedule, which can differ for POS 02 and POS 10.	Some plans pay telehealth at parity with in-person visits, others do not.

Multi-state care

Licensure generally follows the patient's location at the time of service, not the clinician's. A provider treating patients in several states needs to be licensed in each one (or covered by an agreement such as PSYPACT for psychologists) and credentialed with each payer that patient's plan uses. We track state and payer requirements so multi-state telehealth practices don't find gaps after claims are denied. If your practice is growing across state lines, our credentialing team can help with enrollment.

Out-of-Network Billing for Therapists

Many therapists stay out of network to control their rates and caseloads. Billing that way still takes work, because the patient often depends on reimbursement.

Superbills that get reimbursed

A superbill is the document a patient submits to their insurer for out-of-network reimbursement. Ours include the provider's name, credentials, NPI and tax ID, patient details, dates of service, CPT and ICD-10 codes, place of service, fees charged, and payments received. A missing field is a common reason a reimbursement request is rejected.

Single-case agreements

If a patient can't find an in-network provider who fits their needs, the plan may agree to cover an out-of-network provider at an in-network rate for that patient. We help request and document these single-case agreements and follow up until the terms are confirmed in writing.

Tracking reimbursement

Out-of-network payment depends on the patient's deductible, coinsurance, and the plan's allowed amount. We track what was submitted, what was paid, and what is still pending, so your practice and your clients aren't left guessing.

Good faith estimates for self-pay clients

Under the No Surprises Act, providers must give uninsured and self-pay clients a good faith estimate of expected charges. We help you build a compliant estimate process for these clients.

IOP and PHP Billing, and Substance Use Treatment Billing

Intensive outpatient (IOP) and partial hospitalization (PHP) programs carry higher revenue and higher billing risk. Daily or per-diem billing, authorization limits, and detailed documentation requirements mean small errors can put many days of care at risk.

IOP and PHP Billing Codes Table

Code	What It Covers	Billing Note
H0015	Alcohol and/or drug services, including intensive outpatient programs (substance use IOP).	Payers and state Medicaid programs vary in whether they accept it. Confirm the code set before billing.
S9480	Intensive outpatient psychiatric services, per diem.	Billed per day, so each billed day needs its own supporting documentation and authorization.
H0035	Mental health partial hospitalization, less than 24 hours.	Confirm the billing unit with each payer, and track authorized days so a cap isn't passed without review.
Revenue codes (for example 0905, 0906, 0912, 0913)	Facility billing for IOP and PHP levels of care.	Used on facility claims, and the codes a payer accepts differ, so verify them for each payer.

Authorization caps and concurrent review

Payers commonly approve IOP and PHP in blocks of days, then require a review to continue. If a review is missed or a cap is reached, the additional days may be denied. We track authorization dates and units so your clinical team knows when to submit updates.

Medical necessity documentation

To support continued stay, payers expect a clear record: the level of care criteria used (such as ASAM), individualized treatment plans, hours and days attended, and progress toward goals. We review documentation against payer expectations before claims go out, and we prepare appeals when a payer disputes the level of care. We can also support the urine drug testing and lab billing that often accompanies substance use treatment.

Top Mental Health Claim Denials and How We Fix Them

Most mental health denials fall into a handful of categories. Here is what we see most often and how we handle each one.

Claim Denial Reasons and Fixes Table

Denial Reason	Typical Cause	How We Fix It
Medical necessity	Vague diagnosis, thin documentation, or a service level the payer doesn't think the record supports.	Review the note against payer criteria, request documentation updates where needed, and submit an appeal with supporting records.
Authorization exceeded or missing	Visits or days beyond the approved amount, or no authorization on file.	Track authorization limits before services occur, request extensions early, and appeal retroactively where the payer allows.
Provider not credentialed or enrolled	The clinician wasn't active with the payer on the date of service.	Verify enrollment status before scheduling, and correct billing under a credentialed provider where appropriate.
Modifier or place of service error	Missing 95 or GT on telehealth claims, or the wrong POS.	Correct and resubmit using the payer's specific rules, and update our billing rules for that payer.
Timely filing	Claims submitted after the payer's filing window.	Submit claims quickly, track filing limits by payer, and document proof of timely submission for appeals.
Rendering vs. billing NPI mismatch	The wrong individual or group NPI on the claim, common in group practices.	Correct the provider setup in the billing system and resubmit affected claims.

Timely filing limits can be as short as 90 days with some commercial payers, while Medicare allows one year from the date of service. Read more about our denial management process.

Frequently Asked Questions (FAQs)

What mental health services do you bill for?

We bill therapy sessions, psychiatric evaluations, medication management, family and group therapy, psychological testing, intensive outpatient (IOP) and partial hospitalization (PHP) programs, and telehealth visits. We handle the full billing cycle: coding review, claim submission, payment posting, denial appeals, and reporting.

Which providers do you bill for?

We bill for psychiatrists, psychiatric nurse practitioners, psychologists, LCSWs, LPCs, LMFTs, and group practices and clinics. Each license type has different codes, payer rules, and credentialing requirements, so we set up billing by license type and payer instead of using one template for everyone.

Can you bill directly from my EHR, like SimplePractice or TherapyNotes?

Yes. We work with SimplePractice, TherapyNotes, TheraNest, Valant, Tebra, AdvancedMD, athenahealth, Kipu, Sunwave, and Credible. You don’t need to change your clinical workflow. If your system isn’t listed, we can work from exports, so ask us.

How much does mental health billing cost?

Our pricing is typically 3% to 8% of collections, meaning you pay a percentage of what we collect for you. Where you land depends on your practice size, specialty mix, and services included, such as credentialing or prior authorization. There are no hidden setup or software fees.

How do you handle authorizations for IOP and PHP programs?

Payers usually approve IOP and PHP in blocks of days, then require a review to continue. We track authorization dates and units, alert your team before a review is due, and check that daily documentation supports medical necessity, so days aren’t denied after a cap or review date passes.

How long does it take to get started?

Most practices are billing with us within 1 – 2 weeks. We start with a billing assessment, connect to your EHR and clearinghouse, and test a small batch. Once we receive complete charges, claims go out within 48 hours. New payer enrollments are a separate process and often take 60-90 days, depending on the payer.

Do you help with credentialing and payer enrollment?

Yes. We help you enroll with major insurance networks and confirm your enrollments are active before claims go out. A clinician who wasn’t active with a payer on the date of service is a common cause of denials, so we check this first

Can you handle billing for out-of-network insurance?

Yes. We prepare superbills with everything insurers require, help request single-case agreements when a client has no suitable in-network option, and track what was submitted, paid, and still pending. We also help you set up good faith estimates for self-pay clients under the No Surprises Act.

What's the difference between CPT 90834 and 90837?

CPT 90834 covers a 45-minute psychotherapy session (38-52 minutes of face-to-face time), and 90837 covers a 60-minute session (53 minutes or more). Bill the code that matches the documented time. Payers review 90837 more closely, so record start and stop times in the note.

How do you keep patient information confidential?

We follow HIPAA privacy and security requirements and sign a Business Associate Agreement with every client before accessing patient data. We use role-based access and encryption in transit and at rest.
