What is Prior Authorization?
Providers must first navigate the prior authorization problem where health care plans, including medicare advantage, assess whether the treatment, procedure, medication, or service provided is essential before deciding to reimburse the service or not.
This prerequisite is typical with expensive services like maintenance drugs, equipment, higher cost services, and inpatient hospital services. Insurers claim that the restraining enables cost saving and appropriate service provision.
At the same time, those who oppose this process claim that prior authorization prerequisites postpone vital attention and are responsible for cumbersome prior authorization denial of easement requests, along with shifting the burden from elderly and others on social support services to medical service providers.

Problems with Prior Authorization: Postponements and Rejections.
While prior authorization may reduce on some spending we see at the same time it also introduces issues for patients.
In 2023 the Kaiser Family Foundation reported that many of the prior authorizations which were denied did in fact get in part overridden on appeal which in turn suggests that the initial decisions may not have been based as very well on what the patient’s health required. Also in that the number of prior authorization denials was large.
Key issues include:
- Delays in access to timely treatment
- Inconsistent decision-making across insurers
- Administrative burden on doctor’s offices and patients
- Limited transparency in prior authorization information and criteria
In some cases, patients end up paying out of pocket or skipping care entirely to avoid the red tape.
Appealing a Denied Prior Authorization Request
If your prior authorization request is denied, you can appeal the decision. Steps to appeal:
- Review the denial letter: It should explain the reason for prior authorization denial and steps for appeal.
- Gather supporting documentation: Your provider can help gather medical records and statements to prove the treatment’s necessity.
- File an appeal: Submit within the given time frame as per your health insurance plan.
- Follow up: You may need to submit additional documentation or request a reconsideration.

Appeals can be time-consuming but are worth pursuing especially since many prior authorization denials are reversed after a thorough review.
How CMS and Lawmakers Are Responding
In response to growing concerns, the Centers for Medicare & Medicaid Services (CMS) has proposed rules aimed at streamlining prior authorization processes and increasing transparency.
Some initiatives include:
- Standardizing prior authorization requirements
- Requiring application programming interfaces (APIs) to allow easier data sharing between providers and payers
- Mandating faster turnaround times for prior authorization decisions
These efforts aim to reduce patient delays, lower administrative burdens, and ensure that medically necessary services are more readily accessible.
