Mental Health billing · Ann Arbor, MI
Mental health billing services in Ann Arbor keep outpatient therapy practices paid while clinicians stay focused on their clients, and 247MBS has done exactly that since 2005.
We manage Michigan Medicaid Health Plan claims, PIHP/CMHSP community mental health billing, and commercial carve-outs for LMSWs, LPCs, LMFTs, and psychologists — backed by a dedicated account manager, a free 360° dashboard, and HIPAA plus SOC 2 Type II security.
Ann Arbor is a university town, and its therapy landscape reflects that. Around the University of Michigan and Michigan Medicine you find one of the densest concentrations of psychologists, PhD/PsyD testing practices, and group counseling offices in the state — many serving graduate students, faculty, and staff who carry commercial plans that carve their behavioral coverage out to a managed org like Optum or Carelon. A short drive away, Washtenaw County community counseling centers serve Medicaid members whose claims route very differently.
That split is the crux of billing here. In Michigan, mild-to-moderate outpatient therapy for Medicaid enrollees is generally paid through the member's Medicaid Health Plan — Meridian, Molina, Blue Cross Complete, HAP CareSource, Priority Health, or UnitedHealthcare Community Plan — while specialty and serious mental illness services flow through the regional PIHP and its Community Mental Health Services Program. A claim sent to the wrong entity is a denial waiting to happen, and a clinician paneled with a plan but not its behavioral network still gets rejected. Getting Ann Arbor claims paid means knowing which door each one walks through.
Commercial coverage adds another layer. Blue Cross Blue Shield of Michigan, Blue Care Network, Priority Health, and HAP dominate the local employer market, and many of those plans hand mental health utilization to a managed behavioral health org that maintains its own panel, its own authorization thresholds, and its own timely-filing clock. A U-M-affiliated psychologist can be fully credentialed with BCBSM medical yet unpaid on therapy claims until the carve-out network processes the enrollment. Add the seasonal churn of a student population — new members every fall, coverage lapses every summer — and eligibility verification stops being a formality and becomes the single most valuable step in the workflow. We treat it that way, checking benefits and network status before the first session so a full caseload never turns into a stack of rejected claims three months later.
Outpatient psychotherapy is coded by documented face-to-face time, and payers reprice the moment the note and the code disagree. The table below shows how a clean Ann Arbor therapy claim is built.
| Service in the session | Code set | What controls payment |
|---|---|---|
| Diagnostic intake evaluation | 90791 / 90792 | 90792 only when a prescriber adds a medical assessment |
| 30-minute psychotherapy | 90832 | 16–37 documented face-to-face minutes |
| 45-minute psychotherapy | 90834 | 38–52 minutes — the payer default |
| 60-minute psychotherapy | 90837 | 53+ minutes plus a time-and-necessity note |
| Family therapy | 90846 / 90847 | 90847 when the client is present |
| Group psychotherapy | 90853 | Per-member, per-session units |
| Teletherapy delivery | POS 10 / POS 02 · modifier 95 | POS 10 for the client's home; 95 for audio-video |
| Testing (psychological/neuropsych) | 96130–96139 | Base plus timed add-on units |
CPT selection follows the midpoint rule, so a 55-minute session justifies the 60-minute code only when the minutes are on the page.
Most lost dollars trace to a handful of preventable denials rather than to unusual cases. On a busy therapy caseload, the same five issues repeat week after week, and each one is a documentation or enrollment fix rather than a coding mystery. Catching them at the front end — before the claim leaves the office — is what separates a practice that collects predictably from one that writes off a slow trickle of revenue every month.

Revenue review

We bill for solo LMSW, LPC, and LMFT private practices; group therapy offices near central campus and in Kerrytown; psychologists and neuropsych testing practices tied to the U-M community; teletherapy platforms serving Washtenaw County and nearby Ypsilanti, Saline, and Dexter; couples and family counseling practices; child and adolescent therapists; and trauma/EMDR clinicians. Testing practices in particular need billing that understands the 96130–96139 base-plus-units structure and the prior authorization many Michigan plans require before a full neuropsych battery, and academic-adjacent groups need clean EAP handling for the flat-rate sessions employers route separately from insurance. Whether you are a single associate building a panel or an established professional group, the workflow scales to your caseload without adding administrative staff you would rather spend on clinicians.
When you outsource to a billing services company that lives in mental health, paneling and coding stop being the bottleneck. 247MBS runs a 99% first-pass clean-claim rate, keeps days in A/R under 25, recovers 90% of the denials we work, and cuts denials by up to 40% — with 98% client retention and a 20-plus-year track record. Coders are AAPC/AHIMA credentialed, and every account gets a named manager rather than a ticket queue.
Outsourcing Mental Health Billing in Ann Arbor works because the hand-off is complete: eligibility and benefits verification before the first visit, denial management and appeals on the back end, and credentialing support so your associates and new hires are enrolled before they see clients. It is the difference between a medical billing services company that just submits claims and a partner that protects the whole revenue cycle.

Medical Billing for Mental Health — the codes, unit rules and denials nationally, without the local layer.
Yes. We identify at intake whether a client's outpatient therapy is a mild-to-moderate benefit paid by the Medicaid Health Plan or a specialty service through the PIHP/CMHSP, and we bill each on its own rails so nothing bounces between them.
We manage CAQH profiles, submit enrollment with Optum, Carelon, and Magellan networks, and track supervised-billing requirements so pre-licensed clinicians bill correctly under their supervisor until independently credentialed.
We scrub every 60-minute claim for documented face-to-face minutes and medical necessity before submission, so a utilization review finds the record already complete. When a plan does request a chart, we assemble and submit the response so your clinicians are not pulled off caseload to fight a review that should never have opened.
From solo practices to multi-provider groups, we bill Mental Health for Ann Arbor practices with a dedicated account manager, certified coders and a live dashboard — so the units, authorizations and appeals that decide your month stop being the thing nobody has time for.
