Prior authorization

Authorization reviews a defined payer request

HealthCare.gov's preauthorization glossary describes a plan decision that a service is medically necessary under its process and cautions that preauthorization is no promise the plan will cover the cost. Plans may also call the process precertification or prior approval.

The word “authorized” needs a complete object. Ask which service, provider, setting, modality, code, units, frequency, and dates the decision covers. A reference number without those fields creates an unreliable release gate.

Clinical recommendations come from qualified clinicians

A qualified clinician assesses the person, involves the client and family, and recommends care within professional scope. The payer applies benefit, medical-necessity, provider, and utilization criteria. Operations staff manage evidence and workflow without changing clinical content to fit an automated rule.

The CASP ABA Practice Guidelines public summary places assessment, treatment planning, implementation, and evaluation within ABA behavioral health care for people diagnosed with autism. The licensed detailed guideline and governing professional rules guide clinical work; payer approval remains a separate coverage decision.

Build one source-linked request record

Useful fields include:

• member, payer, product, plan, and eligibility dates
• requested service and whether the request is initial, concurrent, renewed, or modified
• requesting, rendering, supervising, billing, and facility providers
• referral, order, assessment, and treatment recommendation when required
• clinical rationale, goals, outcome data, risks, and coordination evidence
• codes, units, frequency, setting, modality, and requested period
• payer policy, form, portal, attachment, and submission version
• received time, status, reference, deadline, owner, and escalation route

Preserve the exact submitted packet. Label later supplements and corrections by date and author.

Read the decision line by line

A response can approve, partially approve, deny, or request more information. Record each service line separately. Capture the authorized provider, location, modality, units, frequency, start and end date, conditions, and denial reason.

Compare the result with the clinician's recommendation and planned schedule. A partial decision may require a family update, revised scheduling, peer-to-peer review, appeal, or continuity work. The payer's action should not silently rewrite the clinical plan.

Current CMS rules have a limited payer scope

The two manifest-required CMS FAQ routes, the current Prior Authorization API FAQ and its earlier initiatives route, describe response content and process rules for impacted payers. The CMS-0057-F page identifies Medicare Advantage, state Medicaid and CHIP, Medicaid and CHIP managed care, and QHP issuers on Federally-facilitated Exchanges.

Beginning in 2026, named process provisions include denial reasons and, for impacted payers other than FFE QHP issuers, 72-hour expedited and seven-calendar-day standard timeframes. The rule concerns medical items and services excluding drugs. Other commercial and employer plans remain outside its mandatory payer scope.

A fictional authorization register

Caleb's fictional clinic reviews sixteen proposed ABA service lines before scheduling. Thirteen match a current written decision for provider, code, units, setting, and dates. Three remain held for a location mismatch, expired date, and missing unit field.

Release readiness is 13 of 16, or 81.3%. The held lines remain in the denominator with owners. The rate measures configuration evidence; it supplies no guarantee of claim acceptance, clean-claim status, adjudication, member cost, or payment.

Recheck before service and billing

Eligibility, benefit, network, authorization, clinical appropriateness, service delivery, documentation, claim submission, adjudication, and payment are separate states. Recheck fields that can change before the visit and again before claim release.

If the request is narrowed or denied, follow the notice. Correction, supplement, resubmission, peer-to-peer review, internal appeal, expedited review, and external review have different clocks and effects.

Track the full authorization lifecycle

Use states that describe actual evidence: preparation, submitted, received, more information requested, clinical review, approved, partially approved, denied, withdrawn, expired, and superseded. Record when each state begins, its source, owner, and next deadline.

A portal label such as “closed” or “complete” may identify workflow completion rather than approval. Map proprietary statuses to the underlying payer artifact before releasing care. When a request is replaced, link the old and new references instead of deleting the first record. This preserves the history needed to explain a gap, partial approval, claim denial, appeal, or later payer audit.

Send the family a dated status summary after every material transition, especially when the payer asks for more information or changes the requested scope. Include the next deadline and responsible contact.

Before scheduling against an approval, reconcile the member, provider, location, codes, units, dates, and conditions to the planned service. Escalate any mismatch before care rather than assuming the payer will correct it during claim review.
