Mental Health Billing Services That Cut Denials and Speed Up Reimbursements
If you run a behavioral health practice and your clean claim rate is sitting under 90 percent, you’re losing real money. Not because your therapists aren’t doing the work. Because mental health billing punishes small mistakes harder than almost any other specialty. A single mismatched modifier on a 90837 claim. A missing prior auth on an Aetna Behavioral Health policy. A 50 minute session billed as 90837 instead of 90834. Each one triggers a denial. Each denial sits in A/R for weeks while your front desk fields patient calls about balances they don’t owe yet.
We fix that.
Medicotech handles end to end mental health and behavioral health billing for psychiatrists, psychologists, LCSWs, LPCs, LMFTs, and group practices across all 50 states. Our coders are AAPC certified. Our team knows the exact difference between Aetna and Aetna Behavioral Health (and yes, those route to different payer IDs). We submit clean claims, chase denials before they age, and keep your A/R days under 30.

What Mental Health Billing Actually Includes
Mental health billing is the process of submitting behavioral health claims to commercial payers, Medicare, Medicaid, and EAPs, then posting payments, working denials, and collecting patient balances. It covers psychiatric evaluations, individual psychotherapy, group therapy, family therapy, crisis intervention, psychological testing, medication management, and telehealth sessions. Done right, it gets your practice paid the full contracted rate within 30 days. Done wrong, it loses 12 to 18 percent of your gross revenue to denials, write offs, and untimely filings.
Medicotech runs the full cycle for behavioral health practices. Here’s what you get.
Eligibility and Benefits Verification
We verify mental health benefits for every new patient before their first session. That means confirming the carve out, deductible status, copay, prior auth requirements, session limits, and whether the diagnosis falls under covered services. About 40 percent of mental health denials come from skipping this step or doing it once at intake and never again.
Prior Authorization
Many commercial plans and most state Medicaid programs require prior auth for psychotherapy beyond a session limit, for higher level codes like 90837, psychological testing, and intensive outpatient programs. We submit the auth request, track approval status, and notify your team before reauthorization is needed. No more delivered services that turn into write offs.
Charge Entry and Claim Submission
Your sessions hit our queue within 24 hours of documentation. We code, scrub against payer specific rules, and submit electronically through clearinghouses. Every claim gets checked for the right CPT code, the right ICD-10, modifier accuracy, and time documentation that matches the code billed.
Mental Health Coding
Our AAPC certified coders work the full mental health code set: 90791, 90837, 90847, 90853, 96130, plus the new G0568 through G0570 collaborative care codes that replaced 99492 through 99494 in 2026. We also handle the SUD HCPCS family for Medicaid claims and E/M plus add on combinations psychiatrists need for medication management.
Telehealth Billing
Telehealth went from optional to permanent for behavioral health in 2026. We bill it correctly. Modifier 95 for the service. POS 10 when the patient is at home — this gets you the non facility rate, roughly 25 percent more than POS 02. We track each payer's individual telehealth rules because they still vary, especially across state Medicaid programs.
Denial Management
Denials get worked, not parked. Our denial management specialist reviews every rejection within 48 hours, identifies the root cause, and either corrects and resubmits or files an appeal. We track denial patterns by payer and feed those back into your charge entry workflow so the same denial does not show up twice.
Payment Posting and Reconciliation
ERAs and EOBs get posted within one business day of receipt. We reconcile against contracted rates — most practices have at least 5 percent of payments coming in below contract without anyone catching it — and flag underpayments for appeal.
A/R Follow Up
Anything aging past 30 days gets actively worked. We call payers, request remittance advice, escalate when a claim is stuck, and pursue secondary billing automatically. Your A/R aging report gets cleaned weekly.
Patient Statements and Collections
We send patient statements with clear EOB context, run a courtesy reminder cycle, and route uncollected balances to a licensed collections partner only with your approval. Patient inquiries route to our toll free number so your front desk stops fielding billing questions.
Credentialing and Re-Credentialing
If you are hiring a new clinician or expanding into a new state, we handle payer enrollment, CAQH maintenance, and re-credentialing every 36 months. Most behavioral health credentialing takes 90 to 120 days. We have cut that to 60 to 75 days for active panels by submitting cleaner applications upfront.
Why Mental Health Billing Is Harder Than Most Specialties
Mental health billing has a unique mix of problems. Practice managers running a primary care office or a cardiology group don't deal with most of these. If you've worked in behavioral health, you already know.
Carve out plans split your patient’s coverage. A patient with Aetna PPO might have their medical care under Aetna and their behavioral health benefits under Aetna Behavioral Health, which uses a different payer ID, different fee schedule, and sometimes different prior auth rules. Bill the wrong payer and the claim denies. We verify the carve out at intake and document the correct payer in your PM system.
Time based codes punish minor errors. A 50 minute therapy session is 90834. A 53 minute session is 90837. The reimbursement difference is roughly $25 per session at the Medicare rate (90834 is around $107, 90837 is around $156). Bill 90837 for a 50 minute session and you’ve upcoded. Bill 90834 for a 60 minute session and you’ve left $25 on the table. Multiply that across 800 sessions a month.
90837 is flagged more than any other psychotherapy code. Insurers run claim audits on 90837 specifically because of historical upcoding. We make sure your documentation supports the code: exact start and stop times, medical necessity for the longer session, and treatment plan goals tied to the work performed.
Prior auth gates change without notice. Optum, BCBS, Cigna Behavioral Health, and most state Medicaid programs update prior auth requirements multiple times a year. Your team can’t track this in real time. We do.
Medicare changed the CoCM codes in 2026. The collaborative care management codes 99492, 99493, and 99494 were replaced by G0568, G0569, and G0570 effective January 2026. LPCs and LMFTs are now covered providers for these services at 75 percent of the Physician Fee Schedule. Most practices missed the transition and lost January and February revenue. We caught it.
Mental health benefits often differ from medical benefits. A patient may have full medical coverage but only 20 outpatient mental health sessions per year. They may have a separate deductible. They may need a referral. We surface this before the session, not after the denial.
Coordination of benefits gets messy. Patients with both Medicare and a commercial secondary need claims sequenced correctly. If your team submits to the wrong primary, both carriers deny.
Mental Health CPT Codes We Bill Daily
Here's a working reference of the codes that drive most behavioral health revenue. Keep this handy. Better yet, hand it to your front desk so they stop guessing on session length.

| 90847 | Family therapy with patient | 26+ min | $122 |
| 90853 | Group psychotherapy | per patient | $30 |
| 90839 | Crisis psychotherapy, first 60 min | first 60 min | $190 |
| 90840 | Crisis psychotherapy, each add 30 | each add 30 min | $94 |

Top Denial Reasons in Mental Health Billing (And How We Stop Them)
Eight denials drive most of the lost revenue in behavioral health. We work on each one before the claim ever leaves your practice.
Time-Based Documentation
Insufficient documentation for time-based codes, such as missing start and stop times on a 90837, leads to immediate denials.
✔ We require exact time documentation in the workflow before submission.Benefit Carve-Outs
Active medical insurance doesn't guarantee behavioral coverage. Patients may have Aetna medical but no mental health carve-out.
✔ We verify before each new patient and re-verify annually.Payer ID Accuracy
Submitting to the wrong entity, like Aetna instead of Aetna Behavioral or UHC instead of Optum, is a common administrative error.
✔ We maintain a payer ID matrix updated quarterly.Prior Authorization
Optum and Cigna require auth for 90837, psychological testing, or sessions beyond plan limits.
✔ We submit auth requests before the session, never after.Documentation Mismatch
Billing a 90837 for 47 minutes or a 90847 without the patient present creates a code-to-note conflict.
✔ We code directly from the clinical note, not a template.Telehealth Modifiers
Errors like missing modifier 95 or using POS 02 instead of POS 10 (home-based) reduce your reimbursement rates.
✔ We apply the correct modifier matrix per individual payer.Credentialing Gaps
New clinicians often see patients before their payer effective dates, leading to uncollectible claims for those dates of service.
✔ We track credentialing status directly against your scheduling system.Timely Filing Deadlines
Commercial payers often have 90-180 day windows, while Medicaid is shorter. Missing these results in automatic write-offs.
✔ We never miss a deadline. If we do, we own the write-off.Behavioral Health Specialties We Bill For
We bill for the full range of mental and behavioral health practices. Each specialty has its own quirks and we handle them.
Outpatient psychiatry. Outpatient psychology. Licensed clinical social work practices. Licensed professional counselor practices. Licensed marriage and family therapy practices. Group therapy practices. Intensive outpatient programs (IOP). Partial hospitalization programs (PHP). Substance use disorder (SUD) treatment. Applied Behavior Analysis (ABA). Telehealth only practices. Multi state group practices. Inpatient and consultation liaison psychiatry.
If your specialty isn’t listed, ask. We’ve probably billed it.
EHR and Practice Management Systems We Work In
We integrate with your existing system. No forced migration. No workflow rebuild.

Frequently Asked Questions
What is mental health billing?
Mental health billing is the process of coding, submitting, and collecting on claims for behavioral health services. It includes psychiatric evaluations, individual and group psychotherapy, family therapy, crisis intervention, psychological testing, medication management, and telehealth sessions. It uses CPT codes (90791 through 90899), ICD-10 diagnosis codes (F01 through F99), and HCPCS codes (H0001 through H0020 for SUD services).
How is mental health billing different from medical billing?
Mental health billing has unique payer carve outs (Aetna Behavioral Health vs Aetna), stricter prior auth rules, time based CPT codes that reward exact documentation, separate session limits per plan year, and 42 CFR Part 2 protections on substance use records. Mental health claims also get audited more aggressively, especially 90837 for upcoding patterns.
What CPT codes do you bill for mental health services?
We bill the full mental health code set: 90791 and 90792 for psychiatric evaluations, 90832, 90834, and 90837 for individual psychotherapy, 90846 and 90847 for family therapy, 90853 for group, 90839 and 90840 for crisis, 90785 for interactive complexity, 90833, 90836, and 90838 as add ons to E/M, 96130 and 96131 for psychological testing, plus the new G0568 through G0570 CoCM codes and 99484 for behavioral health integration.
Do you bill telehealth mental health sessions?
Yes. We use modifier 95 with POS 10 when the patient is at home and POS 02 when in another facility. POS 10 pays the non facility rate, which is roughly 25 percent higher than the facility rate for most psychotherapy codes. We track payer specific telehealth rules including state Medicaid variations.
What is your clean claim rate for mental health practices?
96 percent. That means 96 percent of claims we submit are accepted on first pass and paid without rework. The industry average for mental health is 85 to 88 percent. We hit 96 percent through pre submission scrubbing, eligibility verification, and a payer rules engine updated quarterly.
How do you handle Aetna Behavioral Health vs Aetna routing?
Aetna and Aetna Behavioral Health route to different payer IDs and have different fee schedules. We verify which entity holds your patient’s behavioral health benefits at intake and document the correct payer in your PM system. Same logic applies to Optum vs UHC, Cigna vs Cigna Behavioral Health, and most BCBS plans with behavioral carve outs.
What is the new G0568 through G0570 CoCM code update for 2026?
Effective January 2026, Medicare replaced the previous CoCM codes (99492, 99493, 99494) with G0568, G0569, and G0570. The new codes also expanded covered providers to include LPCs and LMFTs at 75 percent of the Physician Fee Schedule. We migrated all client claims to the new codes in December 2025 so no January reimbursements were lost.
Do you handle credentialing for mental health providers?
Yes. We handle initial payer enrollment, CAQH maintenance, NPI updates, and re credentialing every 36 months. Initial credentialing for behavioral health typically takes 90 to 120 days. Our average is 60 to 75 days because we submit cleaner applications and follow up weekly.
Is Medicotech HIPAA compliant?
Yes. We are HIPAA compliant, sign a BAA before any data access, run SOC 2 controls, and use AES 256 encryption at rest with TLS 1.3 in transit. We also handle 42 CFR Part 2 protected substance use records under heightened access controls.
How much does mental health billing cost?
Our pricing is a percentage of collections, typically 4 to 8 percent depending on your volume, specialty mix, and payer mix. No setup fees, no long term contracts, no hidden charges. You pay only when we collect. The free 90 day billing audit is included before any engagement.
What's the free billing audit?
We pull your last 90 days of claims and review denial patterns, missed revenue, coding errors, A/R aging, and credentialing gaps. You get a written report within 5 business days. If you engage us, the findings get fixed in onboarding. If you don’t, you keep the report.
How long does onboarding take?
14 to 21 days for most behavioral health practices. We connect to your PM/EHR, build your payer matrix, assign your dedicated billing team, and start submitting current claims while we work existing A/R aging in parallel.
