Behavioral health billing is built on time, authorization, and credentialing, and all three shift from payer to payer. Therapy codes are time based, many plans cap sessions or require authorization for continued care, and associate level clinicians often cannot bill directly unless a payer allows supervised billing under a licensed clinician. A practice that treats behavioral health like general office billing will see denials that have nothing to do with the care delivered.
MedPlus RCM provides medical billing, coding, credentialing, and denial management for psychology and behavioral health practices, built around therapy coding, psychological testing, telehealth rules, and the supervision arrangements that govern who can bill.
Psychology & Behavioral Health billing challenges
Individual psychotherapy follows the same time thresholds as the rest of behavioral health: 90832 for 16 to 37 minutes, 90834 for 38 to 52 minutes, and 90837 for 53 minutes or more, with the code chosen by documented minutes rather than the scheduled appointment length. Intake uses the psychiatric diagnostic evaluation code 90791, and the wider service mix includes family psychotherapy with the patient present (90847) and without the patient present (90846), group psychotherapy (90853), and crisis psychotherapy (90839 with add-on 90840). Psychological and neuropsychological testing carries its own code families and documentation requirements, and payers commonly require authorization for testing and for extended psychotherapy sessions before they are delivered.
Authorization and session limits are a constant management task. Many plans set annual session limits or require reauthorization for ongoing therapy, and extended sessions billed as 90837 draw extra scrutiny, with some payers requiring preauthorization for repeated use. Treatment plans, progress notes, and diagnostic justification are commonly requested to demonstrate medical necessity, and the diagnosis on the claim must support the service billed. A therapy claim paired with a diagnosis that does not justify continued treatment is a straightforward medical necessity denial.
Credentialing and supervision rules are the third pressure point. Therapists generally need individual contracts with mental health panels, and whether a supervisee can bill under a supervisor’s National Provider Identifier depends on the payer and the state. Medicare generally requires incident-to supervision, meaning the supervisor is physically present in the office suite and immediately available, for work to bill under the supervisor’s identifier. Commercial payers vary widely: some allow supervised billing with documented supervision, others require the associate to be independently credentialed. Billing under a supervisor’s credentials without an explicit payer arrangement in place risks denials and compliance problems.
Telehealth is now central to behavioral health, but its rules are not uniform. Most payers use the same therapy codes for telehealth as for in-person visits, with modifier 95 for real time audio visual sessions, place of service 10 when the patient is at home and place of service 02 when the patient is at another location. Audio only coverage and in-person visit requirements vary by payer and by program, so modality must be documented explicitly and each payer’s current policy confirmed.

Frequently asked questions
How are therapy session codes chosen?
By documented psychotherapy time: 16 to 37 minutes is 90832, 38 to 52 minutes is 90834, and 53 minutes or more is 90837. Documentation time and record review do not count toward psychotherapy time for standalone codes.
Can an associate or intern bill under a supervisor?
It depends on the payer and the state. Some payers allow supervised billing with documented supervision, others require independent credentialing, and Medicare incident-to rules require the supervisor to be present in the office suite and immediately available. We verify the arrangement before claims go out.
Do therapy sessions need prior authorization?
Often, especially extended sessions, psychological testing, and intensive outpatient programs. Many plans also cap sessions per year, so authorization status and remaining sessions should be checked before scheduling.
How is telehealth behavioral health billed?
With the same therapy codes as in-person visits, plus modifier 95 for real time audio visual sessions and the correct place of service. Audio only coverage varies by payer, so the modality should be documented in the note.
What documentation supports medical necessity?
Presenting symptoms, diagnosis, treatment goals, session frequency and modality, and risk assessment where applicable, with progress notes that show why continued treatment is needed.
