Behavioral & Mental Health

Behavioral health revenue is won at the authorization, not the appeal

Psychiatry, therapy, ABA, SUD, and IOP/PHP claims fail for reasons medical billing rarely sees: expired units, session minutes that do not match the code, telehealth rules that changed last quarter. MBS bills behavioral health to those rules specifically — inside your system, with a named lead who knows your payers.

Behavioral health clinician meeting with a patient in a private office

Auth-first

Units and dates tracked before the session, not after the denial.

Time-based

Coded to documented session length, every claim.

Program-aware

Outpatient, IOP, PHP, and residential billed to their own rules.

HOW WE HOLD THE WORK

Behavioral health data carries stricter rules than the rest of the chart

Below is what governs the work, the controls we operate under, and what your team can expect from us in writing.

Standards the work is held to

  • HIPAA Privacy & Security RulesPHI is handled under a signed business associate agreement, with access limited to the staff assigned to your account.
  • Payer medical-necessity criteriaAuthorizations, level-of-care changes, and appeals are written against the criteria the specific payer publishes — not a generic template.
  • Current CPT and code-set rulesTime-based psychotherapy, ABA, and telehealth code rules are re-checked each cycle and applied to the documented session, not assumed.

Compliance highlights

Role-based access

Only the named team on your account can reach your system and records.

Dedicated account manager

You get a named account lead and a defined escalation path.

Named account lead

One accountable point of contact who knows your payers and programs.

Work inside your system

We bill in your EHR or PM system, so your audit trail stays intact.

01

The authorization decides the claim

In behavioral health, most lost revenue is decided before the session happens. We track authorized units, date spans, and renewal windows per patient, and flag a lapse while there is still time to fix it.

02

Minutes are money

Time-based codes only survive review when the note states start and stop time and the units match. We code to the documentation and query the clinician when the two disagree — before submission.

03

Medical necessity is written, not assumed

Payers reviewing continued care want progress, not attendance. We tell you which documentation patterns are drawing review, by payer, so the next round of notes holds up.

WHO WE BILL FOR

Every behavioral health setting has its own denial profile

A solo therapist and a 30-bed residential program are not the same billing problem. We scope to the setting, not to a generic behavioral health template.

  • Psychiatry & telepsychiatry
  • Psychology, counseling & therapy
  • Applied Behavior Analysis (ABA)
  • Substance use disorder / addiction medicine
  • Intensive outpatient (IOP) & partial hospitalization (PHP)
  • Eating disorder treatment programs
  • Neuropsychological testing
  • Group practices & multi-clinician networks

Denial ledger

The six denials that take most behavioral health revenue

Not a generic list. These are the reason codes that dominate behavioral health A/R, what actually causes them, and the control we put in place so they stop repeating.

No authorization on file / units exhausted

Auth expired mid-episode, or the unit count on file never matched what was scheduled.

Per-patient auth ledger with unit burn-down and renewal alerts ahead of the last authorized visit.

Units inconsistent with documented time

Session length in the note does not support the code or the number of units billed.

Pre-submission time-and-units check, with a clinician query instead of a downcode-and-hope submission.

Telehealth modifier or place of service mismatch

Payer-specific modifier and POS rules changed and the template did not.

Payer-by-payer telehealth matrix maintained on our side and applied at scrubbing.

Not medically necessary / continued care denied

Notes document attendance and stability rather than measurable progress or ongoing need.

Appeal with the clinical record assembled, plus a documentation debrief so it stops repeating.

Duplicate or overlapping services

Group and individual sessions, or two clinicians on the same day, billed without the distinction shown.

Same-day logic checked against payer rules before the claim leaves, with modifiers applied where allowed.

Timely filing lost during intake backlog

Charges sat behind an unsigned note or an incomplete registration.

Charge-lag report by clinician, worked weekly so nothing ages into a write-off.

Working cadence

What we do, and when we do it

Behavioral health cash flow is rhythm-sensitive. Authorizations lapse on a calendar and notes age quickly, so the work is scheduled rather than reactive.

Sample view for illustration — not client data.

  1. Before the session

    Eligibility, benefits, and authorization

    Behavioral health benefits are verified separately from medical. We confirm coverage, visit limits, and authorization status, and surface what needs a renewal request this week.

  2. Within 24 hours

    Charge review and coding

    Codes, units, modifiers, and place of service checked against the note. Anything ambiguous goes back as a query the same day rather than as a guess on the claim.

  3. Daily

    Submission and rejection work

    Claims out daily; clearinghouse rejections corrected the same business day so nothing waits for a weekly sweep.

  4. Weekly

    Denials, appeals, and A/R

    Denials grouped by reason code, appeals filed with the clinical record attached, and aging worked by bucket and payer.

  5. Monthly

    Pattern review with your clinical lead

    Which payers are reviewing which documentation, where authorizations are slipping, and the two or three changes that would move next month's collections.

Program-specific notes

Outpatient therapy & psychiatry

High visit volume, thin per-claim margin. First-pass accuracy and charge lag decide profitability more than appeal volume does.

ABA

Assessment versus treatment codes, supervision and concurrent-service rules, and authorizations measured in units make this the most auth-intensive service we bill.

SUD / addiction medicine

Bundled and per-diem arrangements, level-of-care changes mid-episode, and lab components that follow separate rules.

IOP & PHP

Per-diem billing with minimum-hours and attendance requirements — a partial day documented like a full one is a denial waiting to happen.

Questions we answer on every behavioral health call

Do you track authorizations, or do we?

We maintain the authorization ledger — units authorized, units used, and the renewal date — and tell your team what needs to be requested. Submitting the clinical request stays with the clinician, since payers want it from the treating provider.

Can you work inside our EHR?

Yes. We work in the behavioral health system you already use rather than requiring a migration. If a template or setting is generating avoidable denials we document it and recommend the change.

How do you handle telehealth rules that keep changing?

We keep a payer-by-payer matrix of modifier and place-of-service requirements and apply it at claim scrubbing, so a payer policy change does not have to become a clinician workflow change.

Will you appeal medical-necessity denials?

Yes, with the clinical record assembled and the payer's own criteria cited. We also bring the pattern back to your clinical lead, because the durable fix is in the documentation, not the appeal.

We run a program, not a practice. Does that change the engagement?

It changes the billing rules considerably — per-diem, minimum hours, and level-of-care transitions. We scope program billing separately from outpatient so the two are priced and reported honestly.
