What information is not required for prior authorization?

Editorial team Published on

Emergency medical care, routine office visits, and standard preventative services do not require prior authorization.

What Does Not Require Prior Authorization

  • Emergency treatments: Care delivered in an emergency room or for sudden, life-threatening medical conditions is exempt.
  • Routine office visits: Standard primary care check-ups and basic consultations generally do not need prior approval.
  • Preventive services: Routine screenings, routine prenatal care, and standard immunizations typically bypass the authorization process.
  • In-network standard care: Many low-cost or standard diagnostic tests and generic medications on a plan’s preferred formulary do not require pre-approval.

Note: Specific rules vary by insurance provider and health plan type. Always check your specific insurer's policy list or portal before receiving care.

What are the new requirements for Medicare prior authorization in 2026?

Starting January 1, 2026, new rules require Medicare Advantage plans to make faster prior authorization decisions, and a new pilot program introduces pre-approval rules for certain Original Medicare services in six states.

Faster Medicare Advantage Decisions

  • Standard requests: Plans must approve or deny standard medical requests within 7 calendar days (down from 14 days).
  • Urgent requests: Urgent or expedited requests must be decided within 72 hours.
  • Clearer denials: If a plan denies a service, it must provide a specific, documented reason in writing.
  • Public transparency: Plans must publicly report their approval and denial rates. You can read more about these limits via U.S. News.

The WISeR Pilot for Original Medicare

  • Target states: Original Medicare now requires prior authorization for specific outpatient services in Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington.
  • Covered services: A total of 17 outpatient procedures—such as certain spinal surgeries, knee arthroscopies, and wound care treatments—now require pre-approval to reduce medical overuse.
  • Details: You can review the full list of procedures through Resource Medicare.

What is a common reason for a prior authorization required rejection?

A common reason for a prior authorization rejection is missing or incomplete clinical documentation. Insurance companies often reject requests because they lack required lab results, imaging reports, or clinical notes.

Other Common Reasons

  • Lack of Medical Necessity: The submitted details do not prove the treatment or medication meets the payer's clinical guidelines.
  • Coding Errors: The CPT (procedure) or ICD-10 (diagnosis) codes are wrong or do not match.
  • Step Therapy Requirements Not Met: The patient did not try or fail lower-cost, preferred alternative treatments first.
  • Non-Formulary Drugs: The requested medication is not on the insurance plan's approved drug list.

What information is required for a prior authorization?

A prior authorization requires patient identification, provider details, specific treatment codes, and clinical documentation proving medical necessity.

Patient and Insurance Information

  • Patient name, date of birth, and contact details.
  • Insurance policy or identification number (such as a Member ID or Medicaid/Access card number).
  • Plan group number and specific insurance program name.

Provider and Facility Information

  • Physician name, phone number, and office contact information.
  • National Provider Identifier (NPI) and tax ID number of the ordering or prescribing doctor.
  • Facility or hospital name and address where the service or procedure will happen (if applicable).

Service or Treatment Codes

  • Procedure or CPT/HCPCS codes describing the specific medical test, surgery, or equipment.
  • National Drug Code (NDC) or specific drug name, dosage, strength, and quantity for medication requests.
  • Diagnosis codes (ICD-10) explaining the medical condition being treated.

Clinical Documentation and Proof of Necessity

  • Letter of Medical Necessity (LOMN) written by the provider to summarize why the treatment is required.
  • Clinical notes from office visits, history and physical (H&P) reports, or progress notes providing context.
  • Diagnostic reports including lab results, blood work, or biopsy reports.
  • Imaging reports such as X-rays, MRIs, or CT scans that visually support the need for the procedure.
  • Treatment history detailing past therapies or "step therapy" trials that were already attempted and failed.

What does it mean if prior authorization is not required?

If prior authorization is not required, it means your health insurance plan does not need to approve a treatment, test, or medication before you receive it for the plan to cover it.

What It Means for You

  • Faster care: You can proceed with the recommended care or fill a prescription immediately without waiting days or weeks for insurance approval.
  • Standard coverage rules still apply: "Not required" does not automatically mean the service is 100% free. Your standard copay, coinsurance, or deductible still apply based on your specific policy.
  • Confirm in-network status: The service or drug must still be a covered benefit under your plan and ideally provided by an in-network provider to avoid unexpected bills.

Understanding Prior Authorization

What are three drugs that require prior authorization?

Many health insurance plans require prior authorization (pre-approval from the insurance company before they will cover the cost) for specialty, high-cost, or controlled medications. Three common examples of drugs that frequently require prior authorization include:

  • Ozempic (semaglutide): Often prescribed for type 2 diabetes, insurers frequently require prior authorization to ensure it is being used for an approved medical condition rather than off-label cosmetic weight loss, or to verify that step therapy requirements (trying preferred alternatives first) have been met.
  • Botox (onabotulinumtoxinA): While widely known for cosmetic use, therapeutic applications like chronic migraine prevention, severe muscle spasticity, or bladder dysfunction routinely require prior authorization from insurance to confirm medical necessity.
  • Humira (adalimumab): As an expensive biologic medication used for chronic inflammatory conditions like rheumatoid arthritis or Crohn's disease, plans require prior authorization to verify diagnosis criteria and ensure patients have tried standard first-line treatments (such as traditional nonsteroidal anti-inflammatory drugs or methotrexate) without success.

What are the five treatments that Medicare will not cover in 2026?

Original Medicare does not cover several common services, including routine dental care, routine vision care, hearing aids, outpatient prescription drugs, and long-term custodial care.

Common Uncovered Services

  • Most dental care: Routine checkups, cleanings, fillings, root canals, extractions, and dentures are excluded.
  • Routine vision care: Eye exams for prescription glasses, eyeglasses, and contact lenses are not covered (except after cataract surgery).
  • Hearing aids: Original Medicare does not pay for hearing exams to fit hearing aids or the devices themselves.
  • Outpatient prescription drugs: Standard Parts A and B do not pay for retail prescription medications, requiring a separate Part D policy.
  • Long-term care: Custodial nursing home care or assisted living (help with daily personal needs like bathing and dressing) is not covered.

Why do doctors hate prior authorization?

Doctors dislike prior authorization because it creates heavy administrative work, delays patient care, and undermines their clinical judgment.

Heavy Administrative Burden

  • Wasted time: Doctors and their staff spend roughly 12 to 16 hours every week filling out forms, faxing documents, and waiting on hold.
  • Burnout: Managing dozens of authorization requests per doctor each week contributes significantly to staff fatigue and physician burnout.
  • Frustrating reviews: The "peer-to-peer" appeals often require doctors to justify clear medical decisions to non-physicians or reviewers outside their specific medical specialty.

Harm to Patients

  • Care delays: Over 90% of physicians report that the approval process delays necessary medical treatment or prescription refills.
  • Adverse health events: Surveys by the American Medical Association show that one-third of doctors report prior authorization leading to serious medical outcomes like hospitalizations or permanent disability.
  • Treatment abandonment: Many patients give up and stop trying to get care when facing complicated insurance roadblocks.

Distrust of Insurance Motives

  • Second-guessing expertise: The process requires doctors to get a third-party corporate insurer's permission to practice medicine they already trained years to perform.
  • Cost-cutting focus: Clinicians feel the system is designed primarily to boost insurance company profits by blocking or delaying costly treatments rather than improving health.

What percent of prior authorizations are denied?

On average, health insurers deny between 12% and 18% of standard prior authorization requests.

Recent health data from KFF Analysis on Prior Authorization Metrics breaks down standard denial rates by insurance market:

  • ACA Marketplace plans: 18% denied (ranging from 3% to 25% depending on the insurer).
  • Medicaid managed care: 14% denied (ranging from 2% to 23%).
  • Medicare Advantage: 12% denied on standard requests (ranging from 5% to 17%), though general volume-based calculations can vary depending on partial versus full denials.

Appeals and Overturns

  • Low appeal rates: Only about 11% of denied requests are formally appealed by providers or patients.
  • High overturn rates: When an appeal does happen, a large percentage of denials are overturned—67% in Medicare Advantage, 47% in Medicaid, and 43% in ACA Marketplaces.

Is it difficult to get prior authorization?

Getting prior authorization is often difficult, time-consuming, and prone to delays.

Why It Is Difficult

  • Administrative Burden: Your doctor's office must submit extensive medical records, proof of medical necessity, and fill out specific forms.
  • Step Therapy Requirements: Insurers often deny requests until you try and fail on a cheaper, alternative treatment first.
  • Delays in Care: Standard requests can take anywhere from a few days to 30 days, while urgent requests generally take up to 72 hours.
  • High Initial Denial Rates: Roughly 25% of initial requests are denied, requiring your doctor to submit additional information or file an appeal. Tools like CoverMyMeds help providers navigate electronic prior authorization to reduce these hurdles.

Common Causes of Delays

  • Missing or incomplete clinical paperwork.
  • High-cost or specialty medications that require extra insurer scrutiny.
  • Insurer requirements for peer-to-peer reviews with doctors.
  • Outdated submission methods like fax or mail instead of electronic portals.
