Prior authorization & medical necessity Glossary

Build the request from clinical evidence

Requested units are the service quantity submitted for payer review under a defined code, unit, period, provider, setting, and rationale. The treating clinician should connect the request to the person's assessment, priorities, goals, risks, feasible schedule, other care, progress, and review plan.

The CASP ABA Practice Guidelines public page places assessment and treatment planning within ABA behavioral health treatment for people diagnosed with autism. Detailed Version 3.0 content is licensed. The public page does not establish a payer's medical-necessity rule or an individual dose.

Administrative staff may assemble current forms, payer requirements, provider data, dates, and attachments. Only an appropriately qualified clinician should decide whether and how clinical goals, dosage, risk, or rationale change.

Read the determination exactly

An authorization determination is the payer or program's decision on a prior-authorization request. Record the approved, denied, partially approved, pended, withdrawn, or redirected state using the actual notice.

A partial authorization approval approves less than the full request or approves only some services, dates, providers, settings, or conditions. Separate the approved and adverse portions. Record the reason, criteria cited, start and end, unit definition, appeal rights, and continuity implications.

HealthCare.gov's preauthorization glossary says preauthorization is not a promise that the health plan will cover the cost. An authorization also does not replace consent, clinical appropriateness, qualified staff, safe access, a clean claim, or adjudication.

Control additional-information requests

A request for additional information asks for material the payer says is needed to complete review. Identify the exact missing item, due date, clock effect, authorized sender, disclosure route, submission channel, and receipt evidence.

Do not send an entire chart when focused information answers the request and privacy rules call for a narrower disclosure. Do not create, backdate, or alter clinical evidence to fit a requirement. A clinician may complete a permitted late entry or addendum under policy with actual dates, authorship, reason, and preserved history.

CMS-0057-F requires impacted payers to provide specific denial reasons and supports electronic exchange for medical items and services excluding drugs. The CMS fact sheet describes the affected payer classes and 2026 or 2027 provisions.

Treat retroactive requests as exceptions

Retroactive authorization is a payer route that considers approval after some or all service occurred. Availability, eligibility, cause, deadline, required evidence, and payment effect vary by plan and law.

Do not treat retroactive review as a routine substitute for a required prospective authorization. Record why service occurred, the authority and clinical decision, family communication, payer guidance, submission, and final outcome. Immediate safety action should follow appropriate emergency pathways rather than wait for routine approval.

Understand utilization management

Utilization management is a payer or program system for reviewing the use, setting, quantity, duration, or medical necessity of covered services. It may include prospective, concurrent, or retrospective review.

The CMS general FAQ confirms CMS-0057-F's impacted payer classes and says commercial plans outside qualifying FFE plans are not mandatory participants under that rule. Payer criteria and processes can still arise from other sources.

For Medicaid managed care, 42 CFR 438.404 addresses notice of adverse benefit determinations within its scope. State programs and managed-care entities can add procedures. Preserve the notice, decision maker, reasons, criteria, dates, and appeal information.

Appeal the adverse part

An authorization appeal asks the payer or program to review an adverse authorization decision under its defined process. Confirm who may appeal, consent or representative authority, level, deadline, expedited eligibility, form, submission route, evidence, peer discussion, external review, and continuation rules.

The clinician supplies accurate clinical evidence and explains why the recommendation fits the person. Operations manages the packet and clock. The payer makes the coverage decision. Counsel addresses disputed legal rights when needed.

Protect the client during review

Tell the client or authorized representative what was requested, what the payer decided, which services or dates are affected, what options exist, and which costs remain uncertain. Use accessible language and communication supports.

A qualified clinician should assess continuity, risk, and alternative supports. A pending appeal or information request does not itself extend approval. Record any service change, responsible decision-maker, consent, notice, and transition plan.

A determination example

A fictional clinic locks 15 authorization determinations whose review window matured. Thirteen have the notice, requested and approved units, reasons, dates, criteria, next right, and family communication, or 13/15, 86.7%. Seven contain an adverse portion; six have a route-ready response by the internal deadline, or 6/7, 85.7%.

The two incomplete determinations and one open response remain visible. Do not calculate overturn rate until decisions mature. Separate full approval, partial approval, upheld denial, withdrawal, administrative correction, and unresolved outcomes.
