Cutting Medicaid and MCO Denials for a Behavioral Health Group

This case study is a representative example based on common patterns Scionis RCM addresses in behavioral health billing engagements. It illustrates our typical approach and the kinds of outcomes providers see.

Executive summary

A behavioral health group serving a largely Medicaid and managed-care (MCO) population was fighting a high denial rate. The denials clustered around time-based psychotherapy coding, telehealth claims, and medical-necessity documentation, three areas where behavioral health billing is especially unforgiving and where each payer applies its own rules.

Scionis RCM introduced behavioral-health-specialized coding, aligned time-based codes to documentation, corrected telehealth modifiers and place-of-service, and strengthened medical-necessity capture. The result was fewer Medicaid and MCO denials, accurate time-based coding, clean telehealth claims, and stronger medical-necessity documentation.

The challenge

Behavioral health billing carries risks that many general billers underestimate, and the group's denials were concentrated in exactly those areas:

• Time-based psychotherapy codes (90832, 90834, 90837) not matching documented session time
• Medicaid and MCO plans each applying different coverage and billing rules
• Telehealth claims denied for incorrect modifiers or place-of-service
• Medical-necessity documentation that didn't consistently support the service billed
• Session limits and prior authorization not tracked, causing avoidable denials

With a Medicaid- and MCO-heavy payer mix, even a modest denial rate translated into significant delayed and lost revenue, and a heavy administrative appeals burden on clinical staff.

Scionis RCM's behavioral health strategy

1. Behavioral-health-specialized coding

We assigned coders experienced in behavioral health, who understand time-based psychotherapy coding and the add-on codes the specialty relies on. We aligned each time-based code (90832, 90834, 90837) to the documented session length, so the code billed always matched what the note supported, removing a common and easily-avoidable denial trigger.

2. Payer-specific Medicaid and MCO billing

Because Medicaid and each MCO apply their own coverage and billing rules, we built payer-specific billing logic rather than a one-size-fits-all approach. Claims were tailored to each plan's requirements before submission, which is what prevents the plan-specific denials that a generic process generates. This connects to our broader denial management work.

3. Telehealth coding and medical-necessity documentation

We corrected telehealth modifiers and place-of-service so the group's heavy telehealth volume was coded cleanly, and we strengthened medical-necessity documentation so the record consistently supported the service billed. Since behavioral health denials so often hinge on telehealth coding and medical necessity, fixing both directly lowered the denial rate. We also put session-limit and prior-authorization tracking in place to prevent authorization-based denials.

Why behavioral health denials are worth fixing at the root

Behavioral health billing sits at the intersection of time-based coding, telehealth rules, medical-necessity documentation, and payer-specific Medicaid and MCO requirements, and denials tend to cluster wherever those get out of sync. Reworking each denied claim one at a time is exhausting and never-ending. By fixing the root causes, accurate time-based coding, correct telehealth billing, strong documentation, and payer-specific logic, Scionis RCM cut the denials at the source rather than just appealing them after the fact.

If your behavioral health organization is buried in Medicaid and MCO denials, the durable fix is specialty expertise applied to coding, telehealth, and documentation, not a bigger appeals pile.
