Mental Health Billing Services Built on Time-Based Coding and MBHO Routing

A 50-minute documented session bills as 90834. The minimum duration for 90837 sits at 53 minutes. Billing 90837 against 50 documented minutes invites downcoding. The pattern then raises audit exposure if a payer sees it repeat.

Self-funded employers often carve out behavioral health to a separate administrator. The behavioral health payer ID on the card may differ from the medical payer ID. Our team confirms the behavioral routing per plan, not per brand. Verification happens before submission.

Each authorization gets tracked against its own start and end date. Claims route to the payer whose authorization governs the date of service. Overlapping windows get reconciled inside the EHR before charge entry. The patient never receives two billings for the same session.

Session counts get tracked per patient, per plan year, inside the PM system. Alerts trigger at 75% of the cap. The clinician then receives a written notice. Extension requests get filed before the cap closes, not after a denial lands.

Pattern analysis opens against the payer and clinician combination. Documented session times get audited against the billed code. Strong documentation encourages an appeal with clinical justification. Weak documentation affects a clinician training session to close the gap upstream.

Medicare audio-only claims carry the FQ modifier. Commercial audio-only claims often carry the 93 modifier instead. POS 10 attaches when the patient sits at home. Each payer's audio-only coverage gets verified per service line.

The 30-day bucket gets reviewed weekly. The 60-day bucket gets reviewed twice a week with payer-side follow-up. The 90-day bucket gets appeals and escalation. The 120+ day bucket gets a recovery plan or write-off recommendation against timely filing rules.

Each claim carries the rendering provider NPI and the billing provider NPI separately. Group NPI sits in the billing field. Individual NPI sits in the rendering field. Taxonomy codes attach per clinician licensure. Mismatched fields trigger rejection at the clearinghouse.

E/M plus psychotherapy add-on claims pair 99213 to 99215 with 90833, 90836, or 90838. Modifier 25 attaches to the E/M when a significant separate service runs alongside the procedure. Modifier 95 attaches when the session runs through telehealth.

CPT 90791 bills as an initial intake. Re-evaluations after an episode-of-care break can repeat the code. Continuous episodes of care use psychotherapy codes for ongoing sessions. Payer rules on episode definition govern the cadence.

Coders flag clinicians whose session timestamps consistently sit above the billed code threshold. A clinician charting 55-minute sessions while billing 90834 loses 23% of revenue per session. The clinician receives documentation training within the same reporting cycle.

Each claim attaches the rendering license to the state where the patient sat during the session. License verification runs per state per clinician. Out-of-state claims route through the right state Medicaid or commercial payer based on the patient's location.

Commercial behavioral claims often route through MBHOs. Medicaid behavioral claims route through state Medicaid or a Medicaid MCO. Rate structures differ by 30 to 60% between commercial and Medicaid. Authorization rules and documentation requirements run on separate frameworks.

Medicare Advantage plans layer plan-specific authorization rules on top of Medicare guidelines. Medicare FFS routes through Medicare Administrative Contractors by region. Modifier and documentation rules carry forward, but prior authorization frequency climbs on the Advantage side.

Pre-authorization gets secured before the first session. Concurrent authorization gets renewed against clinical updates at fixed intervals. The PM system tracks both expiration dates. Renewal requests get filed 7 to 10 days before each expiration, never after.

Self-pay rates and contracted rates sit on separate fee schedules inside the PM system. Patients using insurance get billed against the contracted rate. Self-pay patients get billed against the cash-pay rate. Cross-application of the two never reaches the patient statement.
