Our certified coders specialize in behavioral health, psychiatry, and therapy billing so your sessions get paid, accurately and on time. [Get a Free Behavioral Health Billing Audit](https://prmsbs.com/contact) We handle behavioral health and psychiatry billing end to end, eligibility and authorization, time-based coding, submission, and denial follow-up. Because mental health claims hinge on precise time documentation and payer-specific limits, a specialty-trained biller protects revenue that general billers routinely lose to denials. ## Behavioral health billing we handle - **Psychotherapy.** 90832 / 90834 / 90837 with correct time thresholds. - **Psychiatric diagnostic evaluations.** 90791 and 90792 (with medical services). - **Psychological & neuropsych testing.** Testing evaluation and administration (96130 to 96139, 96146). - **Interactive complexity.** Add-on 90785 documented and billed where applicable. - **IOP, PHP & MAT.** Intensive outpatient, partial hospitalization, and medication-assisted treatment for substance use. - **TMS & collaborative care.** Transcranial magnetic stimulation (90867 to 90869) and collaborative care management (99492 to 99494). - **E/M + psychotherapy add-ons.** Combined medication-management visits coded correctly. - **Group & family therapy.** 90846 / 90847 / 90853. - **Crisis and add-on codes.** Accurate, documented reporting. - **Telehealth.** Correct POS and modifiers per payer, kept current with policy changes. **Why it matters.** A single 90837 denied for insufficient time documentation, or a session denied for an exceeded limit, is revenue you already earned. We prevent these at the front end and appeal the ones payers get wrong. ## Why behavioral health practices lose revenue The common leaks: wrong psychotherapy time code, missing or exceeded authorizations, telehealth claims filed with outdated POS/modifiers, parity-related denials, and add-on codes billed incorrectly. These are small errors with big cumulative cost across a high-volume therapy schedule. ## What you get with PRMS ### Time-code accuracy Psychotherapy coded to documented time, reducing takeback and denial risk. ### Auth & limit tracking Authorizations and session limits monitored so visits aren't denied. ### Telehealth current We keep pace with changing telehealth rules that hit behavioral health hardest. ## Behavioral health billing FAQs **What makes behavioral health billing different? Behavioral health mixes time-based psychotherapy codes (90832/90834/90837), psychiatric evaluations (90791/90792), E/M with therapy add-ons, and group/family therapy, each with strict time documentation and frequency rules. Mental health parity, session limits, and payer-specific authorization requirements add complexity that general billers often mishandle. **Do you bill telehealth for therapy and psychiatry? Yes. We apply the correct place-of-service codes and telehealth modifiers (e.g., 95, GT) per payer, and keep up with the frequently changing telehealth rules that heavily affect behavioral health. **Can you handle prior authorizations and session limits? Yes. We track authorizations and per-plan session limits so claims are not denied for exceeded visits or missing auth, a leading cause of behavioral health denials. **Do you work with solo therapists and group practices? Both. From an individual LCSW or psychologist to a multi-provider psychiatry group, we scale the same certified coding and denial follow-up to your practice. **Do you bill for psychiatry, psychology, and independent therapists? Yes. We bill for psychiatrists, psychologists, LCSWs, LPCs, and LMFTs, and group mental health practices, matching each provider type to the correct psychotherapy, evaluation, testing, and E/M codes. **Can you help a therapist get credentialed to accept insurance? Yes. Getting on insurance panels is often the hardest part of starting a mental health practice. Our credentialing team handles CAQH, payer enrollment, and panel applications so you can accept insurance and bill in-network, and credentialing is free for our billing clients. ## Related services & specialties Explore our full [billing, coding & denial management services](https://prmsbs.com/services) and [provider credentialing](https://prmsbs.com/medical-credentialing/) (essential for new therapists joining payer panels), or see other specialties we bill including [10+ more](https://prmsbs.com/specialties/).
