What Is Types of prior authorization?
Prior authorization falls into five distinct categories based on timing and clinical context. Understanding which type applies determines the submission process, required documentation, and the payer’s decision timeline.
The Five Types of Prior Authorization in Healthcare
Prior authorization falls into five distinct categories based on timing and clinical context. Understanding which type applies determines the submission process, required documentation, and the payer’s decision timeline.
1. Prospective (Standard) Prior Authorization This is the most common type. It happens before the service is delivered. Elective surgeries, specialty referrals, advanced imaging (MRI, CT, PET), and non-formulary medications all typically require prospective PA. The provider submits the request with clinical documentation, and the payer reviews it before approving or denying the service.
2. Concurrent Prior Authorization Concurrent PA applies during an ongoing episode of care. The most common example is inpatient hospital stays where the payer requires periodic reviews to continue coverage. If a patient is admitted for 5 days but the initial PA covered 3, a concurrent review must be submitted before day 3 ends or the remaining days may not be reimbursed.
3. Retrospective Prior Authorization Retrospective PA is requested after the service has already been delivered. This typically applies to emergency admissions, administrative oversights, or situations where the patient’s eligibility was not confirmed at the time of service. Payers allow retro auth within a narrow window, usually 24-72 hours after an emergency admission.
4. Urgent (Expedited) Prior Authorization Urgent PAs apply when a delay would seriously jeopardize the patient’s health. Under CMS-0057-F, payers must respond within 72 hours for urgent requests. The provider must document why the request qualifies as urgent and clearly flag it in the submission.
5. Emergency Prior Authorization Emergencies do not require PA before treatment. Care is delivered first. Authorization is obtained retroactively, typically within 24-48 hours of the emergency admission. The distinction from standard retrospective auth is that emergency retro auth has specific payer carve-outs and documentation requirements tied to the emergency department visit.
Outpatient Prior Authorizations: Step-by-Step Process
Outpatient PAs cover procedures and treatments performed outside a hospital admission: diagnostic imaging, physical therapy, specialty consultations, outpatient surgeries, and certain medications.
Step 1: Verify eligibility and PA requirements. Log into the payer portal. Confirm the patient’s coverage is active through insurance eligibility verification and check whether the specific CPT/HCPCS code requires PA under their plan.
Step 2: Gather documentation. Collect patient demographics (Member ID, DOB), provider details (name, NPI, service location), procedure details (CPT/HCPCS codes, ICD-10 diagnosis codes, service dates), and clinical support (progress notes, lab results, imaging reports).
Step 3: Submit the request. Use the payer’s electronic portal whenever possible. Select “Outpatient Authorization” as the request type. Attach all supporting clinical documentation. If the payer does not support electronic submission, fax the completed PA form with cover sheet.
Step 4: Track and document the outcome. Monitor the portal for status updates. If pending beyond 5 business days, call the payer. Document the approval or denial (including transaction/reference ID) in the patient’s record and the practice management system.
Pro Tip: Always save a copy of the approval letter. Payers occasionally lose records during system migrations, and having the original approval on file protects you during audits and claim disputes.
Inpatient Prior Authorizations: Scheduled vs. Emergency Admissions
Inpatient PAs involve hospital stays, including planned surgeries, extended observations, and emergency admissions that convert to inpatient status.
For Scheduled Admissions (Prospective PA):
- Verify insurance eligibility and benefits for the procedure
- Submit the PA request with the hospital’s NPI, expected length of stay, attending physician information, and clinical justification
- Obtain approval before the admission date
For Emergency Admissions (Retrospective/Concurrent PA): – The patient is admitted first. PA is requested within 24-48 hours – Include emergency room documentation, attending physician notes, and medical necessity justification – Most payers have specific emergency admission notification lines. Use them instead of the standard PA portal
For Extended Stays (Concurrent Review):
- If the patient’s condition requires a longer stay than initially authorized, submit a concurrent review before the approved days expire
- Provide updated clinical notes showing why additional days are medically necessary
- Track concurrent review deadlines with automated calendar alerts. Missing a concurrent review deadline is one of the top reasons for denied inpatient days
Pro Tip: Submit concurrent reviews 24-48 hours before the authorized days expire, not on the last day. Payers take up to 24 hours to process concurrent reviews, and a gap in authorization can result in the entire extended stay being denied.

Urgent Prior Authorizations: When Every Hour Matters
Urgent PAs apply when delaying treatment would seriously harm the patient. Under CMS-0057-F (effective January 1, 2026), payers must render urgent PA decisions within 72 hours. When these requests stack up faster than your team can flag and follow up on them, a dedicated urgent prior authorization service can keep the 72-hour clock from running out.
What qualifies as urgent:
- A condition that could deteriorate without prompt treatment
- Post-surgical complications requiring immediate intervention
- Medications needed to prevent serious harm (e.g., chemotherapy, insulin pump supplies, psychiatric medications during a crisis)
Step 1: Flag it as urgent immediately. When submitting through the payer portal, select the urgent/expedited option. If submitting by phone, clearly state “This is an urgent prior authorization request” at the start of the call.
Step 2: Provide clinical justification. Include the diagnosis, current clinical status, what happens if treatment is delayed, and supporting documentation (labs, imaging, physician notes).
Step 3: Follow up aggressively. Do not wait for the payer to call back. Follow up within 24 hours if no response. Document every interaction including the representative’s name, call reference number, and stated timeline.
Step 4: Notify all stakeholders. Once approved, inform the ordering physician, the facility or pharmacy, and the patient. Attach the urgent authorization letter to the patient’s file and scheduling system.
For practices in Texas: Physicians who qualify under the Gold Card Law (HB 3459) with a 90%+ PA approval rate are exempt from PA for those specific services, eliminating the urgent PA bottleneck entirely for qualifying providers.
Drug and Medication Prior Authorizations
Medication PA is the category that generates the most patient complaints and the most staff phone time. The 2024 AMA survey found that 82% of physicians say PA sometimes leads to patients abandoning treatment entirely.
Common triggers for drug PA:
- Non-formulary medications (brand-name when a generic exists)
- Step therapy requirements (must try Drug A before Drug B is approved)
- Specialty medications (biologics, oncology drugs, gene therapies)
- Quantity limit overrides
The process: 1. The prescriber sends the prescription to the pharmacy 2. The pharmacy runs it through the PBM (pharmacy benefit manager). If PA is required, the PBM sends a rejection back to the pharmacy 3. The pharmacy notifies the prescriber’s office 4. The prescriber’s office submits the PA request to the PBM or health plan with clinical justification for why the specific drug is needed 5. The PBM reviews and issues approval, denial, or a request for additional information
Electronic PA (ePA) reduces processing time significantly. According to Surescripts, ePA can cut medication PA turnaround from days to hours. Despite this, electronic PA adoption remains below 30% industry-wide (CAQH CORE Index 2023).
Can medical assistants do prior authorization? Yes. In most states, medical assistants can initiate and process PA requests, including drug PAs, under physician supervision. They cannot make clinical decisions, but they can gather documentation, submit requests, track status, and communicate outcomes. Many practices assign dedicated MAs as PA specialists to reduce errors and turnaround time.
State-by-State PA Rules: Florida, Texas, and Ohio
PA rules vary significantly by state, especially for Medicaid managed care. Here is what practices need to know in three high-volume states.
Florida:
- All Medicaid recipients are enrolled in Statewide Medicaid Managed Care (SMMC) plans. Each MCO (Sunshine Health, UHC Community Plan, Humana) has its own PA portal and requirements
- Standard PA decisions: 7 calendar days. Urgent: 72 hours (CMS-0057-F aligned)
- As of January 30, 2026, several FL MCOs removed PA requirements for certain pediatric service codes
Texas:
- TMHP handles PA for fee-for-service Medicaid. PA must be obtained within 3 business days of the service date
- Gold Card Law (HB 3459): Physicians with 90%+ PA approval rates over a 12-month look-back period are exempt from PA for those services. HB 3812 (effective September 1, 2026) extends the evaluation window to one full year
- Despite the law’s intent, only about 3% of Texas physicians have earned Gold Card status
Ohio:
- Ohio Medicaid adopted CMS-0057-F standards on January 1, 2026: 7-day standard / 72-hour urgent decision windows
- MCOs use uniform PA forms for behavioral health and substance use disorder services
- The Ohio Department of Medicaid publishes a public PA requirements list by service type, updated regularly
Why this matters: A PA submitted with the wrong timeline expectation or to the wrong portal wastes days. Knowing your state’s rules prevents that.
2026 CMS-0057-F: What Changes for Prior Authorization This Year
The CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F) is the biggest structural change to PA in a decade. Key provisions are now live or approaching enforcement.
Already in effect (January 1, 2026):
- Standard PA decisions must be rendered within 7 calendar days (down from 14)
- Urgent PA decisions must be rendered within 72 hours
- Payers must provide a specific reason for every PA denial, not just a generic “not medically necessary” response
Coming March 31, 2026: – Payers must publicly report PA metrics for calendar year 2025, including approval/denial rates, average decision times, and appeals outcomes
Coming January 1, 2027:
- All impacted payers must offer FHIR-based Prior Authorization APIs, allowing providers to check PA requirements, submit requests, and receive decisions electronically through their EHR systems
- This is expected to reduce the average PA processing time from days to minutes for standard requests
What this means for your practice:
- If a payer exceeds the 7-day or 72-hour window, document it. CMS enforcement creates accountability
- Start asking your EHR vendor about FHIR PA API readiness for 2027
- Use the public metrics reports (available March 2026) to identify which payers have the highest denial rates and adjust your documentation strategy accordingly
Why Practices Outsource Prior Authorization Management
At 39 PA requests per physician per week and 13+ hours of staff time dedicated to PA paperwork (AMA 2024 PA Survey), most practices cannot absorb PA workload without sacrificing patient care or burning out their staff.
The math on in-house PA staffing: A full-time PA coordinator in the U.S. costs $42,000-$58,000/year in salary alone (MGMA 2024 compensation data). Add benefits, training, turnover costs, and the revenue lost during vacancies, and the true cost often exceeds $70,000 per FTE.
Outsourcing comparison: Staffingly’s PA specialists work at $399/week (volume discounts to $299/week) with no benefits overhead, no training gaps, and 48-72 hour onboarding. That translates to 65-70% cost savings compared to in-house hires.
What outsourced PA teams handle:
- All five PA types: prospective, concurrent, retrospective, urgent, and emergency
- Payer portal submissions across 50+ EHR systems
- Concurrent review tracking with automated deadline alerts
- Denial follow-up and appeals documentation
- Drug PA and step therapy requests
Results from Staffingly’s 800+ provider network:
- 99.2% clean claim rate
- SOC 2 Type II, HITRUST, ISO 27001, and HIPAA compliant
- 4.9 client satisfaction rating
Outsourcing PA does not mean losing control. It means your clinical staff treats patients while trained PA specialists handle the administrative burden that consumes 13 hours of their week.
What Did We Learn?
- Prospective PA is the standard pre-service approval required for elective procedures, imaging, and non-formulary drugs
- Concurrent PA keeps inpatient coverage active during extended stays. Miss the deadline and the remaining days are denied
- Retrospective PA covers emergency admissions and administrative oversights, but the window is narrow (24-72 hours)
- Urgent PA requires 72-hour payer response under CMS-0057-F. Flag it immediately and follow up within 24 hours
- Drug PA is the highest-friction category. ePA tools cut processing time significantly but adoption remains below 30%
- CMS-0057-F changes (7-day standard, 72-hour urgent, public metrics, FHIR APIs by 2027) are reshaping PA across every payer
- Outsourcing PA to trained specialists at $399/week (volume discounts to $299/week) saves 65-70% versus in-house staffing while maintaining a 99.2% clean claim rate
Q1: What are the main types of prior authorization in healthcare? The five types are prospective (before service), concurrent (during ongoing care), retrospective (after service delivery), urgent/expedited (time-sensitive cases), and emergency (care first, auth after). Each has different submission timelines, documentation requirements, and payer response windows.
Q2: Can medical assistants do prior authorization? Yes. In most states, medical assistants can initiate PA requests, gather clinical documentation, submit forms through payer portals, track status, and communicate outcomes under physician supervision. They cannot make clinical decisions or determine medical necessity, but they handle the bulk of the administrative PA workflow.
Q3: How long do payers have to respond to a prior authorization request? Under CMS-0057-F (effective January 1, 2026), payers must respond within 7 calendar days for standard requests and 72 hours for urgent/expedited requests. Previously, standard timelines were up to 14 days. Emergency admissions typically require notification within 24-48 hours with retrospective auth following.
Q4: What is the difference between prospective and retrospective prior authorization? Prospective PA is obtained before the service is delivered. It is the standard process for planned procedures, imaging, and medications. Retrospective PA is obtained after the service has already been provided, typically for emergency admissions or situations where eligibility was not confirmed at the time of service. Retrospective auth has a much shorter submission window and higher denial risk.
Q5: How much does it cost to outsource prior authorization? Staffingly’s PA specialists start at $399/week (volume discounts to $299/week), compared to $42,000-$58,000/year for an in-house PA coordinator (before benefits and overhead). That represents 65-70% cost savings. Outsourced teams handle all PA types across 50+ EHR systems, with 48-72 hour onboarding, SOC 2 Type II and HIPAA compliance, and a 99.2% clean claim rate across 800+ providers.
