Why Learning How to Do a Prior Authorization Can Save Your Practice Time and Money
How to do a prior authorization — quick answer:
- Verify eligibility — Confirm the patient’s active insurance coverage and check if the service or medication requires PA using the payer’s portal or CPT lookup tool.
- Gather documentation — Collect clinical notes, diagnosis codes (ICD-10), procedure codes (CPT/HCPCS), and any prior treatment history.
- Submit the request — Use the payer’s preferred channel: electronic portal (Availity, CoverMyMeds), EDI, or fax.
- Track and follow up — Monitor the request every 1–2 business days. Under the 2026 CMS rule, payers must respond within 7 calendar days (standard) or 72 hours (urgent).
- Record the outcome — Log the authorization number, effective dates, and include it on every billing claim.
If paperwork buries your practice before you treat a single patient, you’re not imagining it. According to the American Medical Association, physicians complete an average of 39 prior authorizations per week, with staff spending roughly 13 hours managing them. That’s nearly two full workdays every week spent chasing approvals instead of delivering care.
The consequences go beyond lost time. Patients wait. As a result, care gets delayed. Ultimately, the staff burns out. And when someone submits a request incorrectly, the whole process starts over.
Prior authorization (PA) is the step where a provider must get a health plan’s approval before delivering a specific service, procedure, or medication. Insurers use it to verify medical necessity and control costs. That’s the theory. In practice, it’s one of the most frustrating administrative workflows in healthcare.
This guide breaks it down into five clear, actionable steps, so your team spends less time navigating red tape and more time focused on patients.
Understanding the Basics of Prior Authorization
Prior authorization is a core component of utilization management. It serves as a cost-control and quality-assurance mechanism used by health insurance plans to evaluate whether a proposed medical service, procedure, or drug is medically necessary, safe, and cost-effective.
While health plans frame this as a way to ensure evidence-based care, providers often experience it as an administrative hurdle. If a service requires prior authorization and you deliver it without securing approval, the payer will deny the claim. This leaves either your practice to absorb the financial loss or the patient with an unexpected, massive bill.
Services, Procedures, and Medications That Require Prior Authorization
Not every medical service requires a green light from the insurance company. Routine office visits, basic preventive screenings, and standard blood tests rarely require prior authorization. However, health plans typically require prior authorization for high-cost, specialized, or frequently overused services. These include:
- Advanced Imaging: Magnetic resonance imaging (MRI), computed tomography (CT) scans, and positron emission tomography (PET) scans.
- Elective Surgeries: Planned inpatient or outpatient surgeries, such as joint replacements or spinal procedures.
- Specialty Medications: High-cost biologics, oncology drugs, and medications requiring complex administration or monitoring.
- Durable Medical Equipment (DME): Items like oxygen concentrators, CPAP machines, or custom wheelchairs.
- Post-Acute and Specialized Care: Physical therapy, occupational therapy, home health services, and hospice care.
Crucially, emergency medical care is legally exempt from prior authorization requirements across all states. If a patient presents with an acute, life-threatening condition, you do not need to wait for a payer’s permission to treat them.
Why Knowing How to Do a Prior Authorization Matters in 2026
The administrative landscape of healthcare has grown increasingly complex. According to AMA survey data, over 94% of physicians report that prior authorizations cause significant delays in patient care. Additionally, 27% report that these delays have led to a serious adverse event for a patient in their care.
Furthermore, the sheer volume of requests is staggering. There are over 35 million prior authorization requests submitted annually for Medicare Advantage patients alone. Understanding how to do a prior authorization efficiently is no longer just a billing task; it is critical to patient safety and the financial health of your practice. For a deeper look, check out the Harvard Health Guide on Prior Authorization and read More info on understanding prior authorization.
Prior Authorization vs. Preauthorization vs. Precertification
In the medical billing world, terminology can vary wildly from one insurance company to another. You will frequently hear three terms used interchangeably:
- Prior Authorization: The standard term for obtaining clinical approval for a specific service or medication.
- Preauthorization: Often used by commercial health plans to describe the same process of verifying medical necessity before care is delivered. You can learn more about this by reading What Is Health Insurance Pre-Authorization | Qualigenix.
- Precertification: Frequently used by plans to describe the process of notifying the insurer of an upcoming inpatient admission or specialized outpatient procedure.
Regardless of the specific word a payer uses in their guidelines, the core objective remains identical: proving to the insurance company that the proposed treatment is clinically indicated and meets their coverage criteria. For more clarity on navigating these terms, see More info on health insurance prior authorization.
How to Do a Prior Authorization: The 5-Step Workflow
Managing authorizations doesn’t have to feel like a chaotic guessing game. By establishing a standardized, highly organized operational workflow, your practice can dramatically reduce administrative errors and accelerate approvals.
Who is responsible for this process? The provider’s office is responsible for initiating and completing the prior authorization request. While patients can sometimes call their insurers to advocate for themselves, health plans require clinical documentation that only the medical provider can supply.
Here is our battle-tested, 5-step workflow to master the prior authorization process. For a comprehensive breakdown of this workflow, see More info on the comprehensive prior authorization process.
Step 1: Verify Patient Eligibility and Requirements
Generally, this mistake happens when staff perform a service without first confirming whether it requires authorization. Billers call this a “no-auth denial” (denial code CO-197). Overturning it is incredibly difficult.This is known in the billing world as a “no-auth denial” (often represented by denial code CO-197), and it is incredibly difficult to overturn.
Your scheduling or front-desk team must verify the patient’s active insurance eligibility first. Do this before scheduling any elective service or prescribing a specialty medication.
- Check the Payer Portal: Log into the appropriate payer portal (such as Availity, ProviderOne, or specific regional portals) to confirm active coverage on the planned date of service.
- Search by Codes: Do not rely on generic descriptions. Use the exact Current Procedural Terminology (CPT) codes, Healthcare Common Procedure Coding System (HCPCS) codes, or National Drug Codes (NDC) for the planned treatment. Use the payer’s online lookup tool to see if these specific codes require prior authorization.
- Identify Delegated Vendors: Be aware that many major payers delegate certain services to third-party utilization management companies. For example, a plan might delegate advanced imaging or musculoskeletal procedures to Carelon or eviCore. Submitting directly to the primary insurer instead of the delegated vendor will result in immediate routing delays.

Step 2: Gather Complete Clinical Documentation
Once you confirm that a prior authorization is required, your next task is to build a bulletproof clinical case. Insurance reviewers are not mind readers; they evaluate requests based on strict, evidence-based guidelines. Most major payers use standardized clinical decision support tools like InterQual or MCG Health to compare your documentation against established clinical criteria.
To prevent delays and immediate denials, compile a complete documentation packet that includes:
- Patient Demographics and Insurance ID: Double-check for transposed numbers or misspelled names.
- Ordering Provider Details: Ensure the provider’s National Provider Identifier (NPI) and Tax Identification Number (TIN) are accurate.
- Accurate ICD-10 and CPT Codes: The diagnosis codes must clearly support the necessity of the procedure codes.
- Relevant Progress Notes: Include the last 6 months of clinic notes detailing the patient’s symptoms, physical exam findings, and clinical progression.
- Conservative Treatment History: Many plans require “step therapy” or conservative management before approving expensive treatments. For example, if you are requesting an MRI for back pain, you must document the exact dates, durations, and outcomes of physical therapy or conservative medication trials (e.g., “patient completed a 6-week trial of physical therapy from March 1 to April 15, 2026, with no improvement”).

Step 3: Submit the Request Through the Right Channel
How you submit your request matters just as much as what you submit. While some practices still rely on manual faxing, electronic prior authorization (ePA) is the fastest, most secure, and most transparent submission method.
For this reason, we highly recommend prioritizing electronic submission channels:
- Payer Portals: Portals like Availity Essentials (widely used by Anthem, BCBS, Aetna, and Humana) allow for direct data entry and often feature interactive questionnaires that can grant real-time approvals.
- Specialized ePA Software: Platforms like CoverMyMeds are invaluable for streamlining pharmacy and medication-related authorizations.
- Direct EHR Integration: Many modern Electronic Health Record (EHR) systems feature built-in ePA modules that pull clinical data directly from the patient’s chart, minimizing manual data entry.
If you must submit via fax, always use the payer’s specific, up-to-date prior authorization form. Place the completed form as page one of your transmission and do not use a generic coversheet, as this can confuse automated optical character recognition (OCR) sorting systems at the insurance company. Discover how digital integrations can speed up your practice by reading More info on how technology is revolutionizing prior authorization.
Step 4: Track and Follow Up on a Schedule
Submitting the request is not the end of the process; it is the beginning of the waiting game. Historically, standard prior authorization reviews could take up to 14 to 30 days, causing massive bottlenecks.
Fortunately, the regulatory landscape shifted dramatically on January 1, 2026, with the implementation of the CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F). This rule significantly tightened decision timelines for impacted payers (including Medicare Advantage, Medicaid managed care, and ACA marketplace plans).
Under the new 2026 CMS regulations, payers must adhere to strict response windows:
To keep your requests moving through the pipeline, establish a strict follow-up schedule:
- Check Status Proactively: Do not wait for a letter in the mail. Build a daily tracking routine into your morning workflow to check the status of pending requests on the payer portals.
- Respond to “Pend” Statuses Within 24 Hours: If a payer pends a request asking for additional clinical information, respond immediately. Under many plan guidelines, failing to provide the requested data within a tight window (often 48 to 72 hours) results in an automatic administrative denial.
For strategies on managing these tight timelines, read More info on streamlining prior authorization.
Step 5: Record the Authorization Number and Handle Outcomes
Once you receive an approval, do not celebrate just yet — there is still vital administrative work to do. An approved prior authorization is a highly specific, time-bound contract.
- Verify the Details: Carefully review the approval letter. Does the approved CPT code match what you plan to perform? Is the approved quantity correct?
- Track the Expiration Date: Prior authorizations are only valid for a specific window (typically 30, 90, or 180 days). If the patient’s procedure is delayed past the expiration date, you must submit a renewal or extension request before the service is rendered.
- Record the Auth Number: Document the approved prior authorization number clearly in your EHR and billing software. This number must be populated in the correct field (such as Box 23 on the CMS-1500 claim form) when the billing claim is submitted. Leaving this number off, or transposing a digit, will trigger an automatic claim denial.

Managing Denials, Appeals, and Gold Carding
Even with a meticulous submission process, denials will happen. In fact, industry data shows that approximately 25% of all prior authorization requests are initially denied. However, a denial is not the end of the road.
Many practices make the mistake of giving up too early. Research indicates that roughly 60% of denied prior authorizations are never appealed, meaning practices routinely walk away from revenue for medically necessary care. This is a massive mistake, especially considering that over 80% of initial prior authorization denials are overturned on appeal for Medicare Advantage plans.
To learn more about the fundamentals of managing these denials, refer to the GoodRx Prior Authorization Guide.
How to Appeal a Denied Prior Authorization
When a denial letter arrives, act quickly. Review the letter to identify the exact reason for the denial. Common reasons include:
- Missing Documentation: The reviewer did not receive the specific clinical notes or lab results required to prove medical necessity.
- Incorrect Codes: A typographical error in the CPT or diagnosis code.
- Step Therapy Failures: The patient has not tried and failed the insurer’s preferred, lower-cost alternative treatments.
Once you identify the issue, choose the appropriate appeal pathway:
- Peer-to-Peer (P2P) Review: This is the fastest and most effective appeal tool. It involves scheduling a phone call between your ordering provider and the insurance company’s medical director. During this 5-to-10-minute call, your provider can verbally explain the clinical nuances of the case. Peer-to-peer reviews have a success rate as high as 75% if conducted within the plan’s designated timeframe (usually 14 to 30 days from the denial).
- Formal Written Appeal: If a P2P is not possible or is unsuccessful, submit a formal written appeal. Next, structure your appeal letter to address the payer’s clinical guidelines directly. Use bullet points to match your patient’s clinical data point-by-point with the insurer’s medical policy criteria. Always attach the supporting objective evidence, such as pathology reports, radiology imaging, or conservative treatment logs.

What is Gold Carding and How Can Providers Qualify?
As the administrative burden of prior authorizations has reached a boiling point, several states and major payers have introduced “Gold Carding” programs.
Gold carding is an administrative relief mechanism that exempts high-performing healthcare providers from standard prior authorization requirements for specific services.
- How to Qualify: Eligibility criteria vary, but programs typically require a provider to maintain a consistently high prior authorization approval rate, usually 90% to 92% or higher, over a consecutive 1-to-2-year period, with a minimum volume of submissions.
- The Benefits: Once “gold-carded,” your practice can bypass the standard submission and waiting process for those approved services. You perform the service and submit the claim, drastically reducing administrative delays and accelerating patient care.
Several states have enacted gold carding legislation, and major commercial payers (such as UnitedHealthcare with its National Gold Card program) have established proprietary pathways to reward compliant practices.
Reducing the Administrative Burden in Your Practice
Chasing insurance approvals is a primary driver of staff burnout and operational inefficiency in modern medical practices. If your clinical team is spending hours on hold with insurance companies, they are not focused on patient care.

Best Practices on How to Do a Prior Authorization Efficiently
To minimize the daily friction of authorizations, implement these operational best practices:
- Centralize Tracking: First, do not rely on sticky notes or individual email folders. Use a centralized tracking spreadsheet or a dedicated module within your EHR to monitor the status, submission dates, and expiration dates of all open authorizations.
- Check Requirements at Point-of-Ordering: Train your clinical staff to check prior authorization requirements when the doctor orders a test or medication, rather than waiting for the scheduling team to find it days later.
- Assign Dedicated Staff: Avoid splitting prior authorization tasks across multiple clinical team members. When responsibilities are fragmented, details get missed. Assigning these tasks to a dedicated specialist allows them to build deep, payer-specific expertise.

Frequently Asked Questions about Prior Authorizations
How long does a prior authorization take under the 2026 CMS rules?
Under the CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F), effective January 1, 2026, impacted payers (including Medicare Advantage, Medicaid managed care, and ACA marketplace plans) must issue decisions within 7 calendar days for standard requests and within 72 hours for expedited or urgent requests.
What happens if a service is delivered without prior authorization?
If a service requiring prior authorization is delivered without an approved authorization on file, the insurance provider will issue an administrative denial (often using denial code CO-197). In most cases, the insurer will refuse to pay the claim, and contractually, you may be prohibited from billing the patient, forcing your practice to absorb the entire cost of the care delivered.
Is prior authorization required in an emergency?
No. Emergency medical care is legally exempt from prior authorization requirements across the United States. If a patient requires immediate, life-saving medical intervention, providers are legally protected to deliver that care without waiting for insurance approval.
