Prior Authorization
Physical Therapy Prior Authorization: A Practical Workflow Guide
Prior authorization is an administrative payer process that may require approval before or during a physical therapy episode of care. A reliable workflow identifies the requirement, records the approval details, tracks utilization, coordinates requested information, and communicates limits to the people who schedule, treat, bill, and follow claims. Requirements vary by payer, plan, provider, setting, service, and date of service. Authorization does not guarantee payment.
01
What Is Prior Authorization in Physical Therapy?
Prior authorization is a payer or utilization-management review that may apply to a service, episode, date range, number of visits, or units. The payer may request administrative and clinical information before issuing a decision. An approval often contains conditions that must be understood and tracked rather than treated as a simple yes-or-no field.
Authorization is not the same as eligibility, referral, medical necessity, or payment. Eligibility concerns coverage status and benefit information. A referral is a separate ordering or plan requirement where applicable. Medical necessity is a clinical or payer determination under applicable criteria. Payment remains subject to the complete claim, coverage, documentation, coding, enrollment, and adjudication circumstances. See Physical Therapy Prior Authorization Services for operational support.
Authorization does not guarantee payment.
02
How Do You Know Whether Authorization Is Required?
Start with the available benefit-verification and plan information for the patient, service, provider, and date of service. Payer portals, plan documents, payer representatives, and a utilization-management vendor may provide relevant information. Record the source, date, reference information, and details of the response so later staff can understand what was checked.
Do not assume that active eligibility means authorization is not required. Do not assume that a rule for one plan applies to another plan from the same payer. Requirements can change and may depend on provider participation, setting, service, diagnosis, or episode circumstances. The Eligibility & Benefits page explains why coverage verification and authorization research remain distinct.
03
What Should Be Recorded When Authorization Is Approved?
Capture the authorization or reference number, payer or vendor, approved start and end dates, approved visits, approved units where applicable, approved services where applicable, expiration conditions, and available reauthorization instructions. Store the approval record in the location defined by the practice's workflow and make relevant details visible to scheduling, clinical, billing, and authorization staff.
Also record who obtained the information, when it was obtained, the source, and any conditions or unanswered questions. A number without its dates and limits is incomplete operational information. If an approval is verbal or portal-based, preserve the available reference, confirmation, or screen documentation according to the practice's policies and permitted system workflow.
04
Visits vs Units
Some approvals are expressed as a number of visits. Others may refer to units, particular services, or a combination of limits. A visit-based approval counts encounters according to the payer's terms; a unit-based approval may require tracking utilization at a more detailed service level. Unit-based authorization is not universal.
The tracking method should match the approval received. Staff should not convert between visits and units by assumption. When the approval language is unclear, document the uncertainty and follow the payer or vendor's available clarification process. Scheduling and billing teams need the same interpretation so usage is not counted differently across systems.
05
Why Approved Dates Matter
An approval may be limited to a specific date range even when visits remain unused. Treatment outside that range can create an authorization mismatch, depending on payer and plan requirements. Tracking only the remaining visits while ignoring the end date can therefore leave the practice with services that appear available operationally but fall outside the recorded approval period.
Dates should be compared with scheduled visits, actual dates of service, claim data, and reauthorization plans. If the payer changes an approval or grants an extension, update the source record and communicate the change. Never alter dates based on assumption; retain the available confirmation supporting the revised information.
06
Reauthorization
Reauthorization is the process of seeking additional or continued approval when the current authorization approaches a visit, unit, service, or date limit. A useful workflow monitors all applicable limits together and identifies which patients may need action before the existing approval is exhausted or expires.
There is no universal lead time. Timing depends on payer instructions, the information required, clinical availability, scheduling, and the patient's expected course of care. The team should define an internal trigger appropriate to the practice and document submission, pending items, payer responses, and the next follow-up date.
07
Documentation Coordination
Payers or utilization-management vendors may request an evaluation, plan of care, progress information, or other records. Revenue-cycle staff can identify the request, track the due date, coordinate retrieval, confirm submission, and preserve reference information. Clinical documentation remains the responsibility of the treating provider.
Administrative staff should not create or change clinical content to satisfy an authorization request. The record should accurately reflect the care and clinical judgment. Submission of requested documentation also does not guarantee authorization or payment; the payer or vendor retains its decision-making role under applicable requirements.
08
Authorization-Related Denials
Authorization-related denials may involve missing approval, expired dates, visits or units beyond approval, services not reflected in the approval, an incorrect authorization number, a delayed request, or information that was not linked correctly to the claim. These are possible patterns, not universal payer rules.
Review the payer response, approval record, claim, dates of service, utilization history, submission evidence, and prior communications before selecting an action. A corrected claim, additional information, reconsideration, appeal, or another response may be appropriate depending on payer instructions and the facts. The claim-denials guide provides a broader root-cause workflow.
09
A Practical Authorization Tracking Workflow
Verify the requirement
Review available payer, plan, patient, provider, service, and date-of-service information; document the source and result.
Identify the submission workflow
Confirm the payer or vendor, required channel, administrative information, and requested clinical records.
Submit required information
Coordinate accurate information, record the submission date, and preserve available confirmation.
Document the approval
Capture the number, dates, visits, units or services where applicable, conditions, and source.
Track utilization
Compare scheduled and completed care with the approval limits using the practice's defined process.
Begin reauthorization when appropriate
Use an internal trigger suited to payer instructions, remaining limits, documentation availability, and expected care.
Communicate limits
Make relevant status and restrictions available to scheduling, clinical, billing, and follow-up staff.

Authorization Tracking Checklist
A shared checklist can reduce incomplete handoffs. Adapt it to the system, payer, plan, and engagement rather than assuming every field applies.
- Payer and plan
- Utilization-management vendor where applicable
- Is authorization required?
- Authorization or reference number
- Approved start date
- Approved end date
- Visits approved
- Visits used
- Visits remaining
- Units approved and used where applicable
- Approved services where applicable
- Is reauthorization needed?
- Documentation requested or required
- Submission confirmation
- Owner and next follow-up date

Connecting Authorization to the Rest of RCM
Authorization data should not remain isolated from scheduling, clinical documentation, billing, denials, and A/R. Billing staff need accurate approval details on the claim where required. Denial staff need the approval record and utilization history. A/R staff need to know whether an authorization issue is being researched or whether another payer status explains the balance.
Repeated authorization-related denials or older balances may reveal a handoff problem rather than a single missed task. Connecting the information helps management see whether requirements are identified, approvals are fully recorded, utilization is monitored, and reauthorization responsibilities are clear. That end-to-end view is part of physical therapy revenue cycle management.

Frequently Asked Questions
Is eligibility verification the same as prior authorization?
No. Eligibility review concerns coverage and benefit information. Prior authorization is a separate approval process that may apply to particular services, dates, visits, or units. Active coverage does not establish that authorization is unnecessary.
Does authorization guarantee payment?
No. Payment remains subject to coverage, claim information, documentation, coding, enrollment, payer adjudication, and the individual circumstances. Authorization does not guarantee payment.
Is a referral the same as authorization?
No. A referral and prior authorization are distinct requirements, although a plan may require one, both, or neither. Confirm the applicable requirements for the payer, plan, provider, service, and date.
Should authorizations be tracked by visits or units?
Track the limit type stated in the approval. Some authorizations use visits, some may use units or services, and others may combine conditions. Do not convert between limit types by assumption.
When should reauthorization begin?
There is no universal lead time. The practice should use payer instructions, remaining visits or units, approved dates, documentation availability, scheduling, and expected care to define an appropriate internal trigger.
