The green prior authorization process is one of the most important – and often most time-consuming – parts of healthcare administration. It ensures that certain services, procedures, or medications are approved by insurers before care is delivered. While it’s meant to confirm medical necessity and control costs, it also requires careful coordination between multiple people: physicians, support staff, billing teams, and insurance companies.
Understanding who’s responsible for each stage makes the process smoother and helps avoid delays or denials. Below, we break down how each role contributes to successful prior authorization.

Physicians Initiate Medical Requests
The process begins with physicians, who determine when a treatment or service requires prior authorization. This typically happens when ordering advanced imaging, prescribing high-cost medications, or recommending surgeries that insurance plans flag for review.
Physicians are responsible for confirming whether pre-approval is required and providing the medical justification for the request. This includes:
- Documenting the diagnosis and treatment plan in the patient’s chart.
- Citing medical necessity based on clinical guidelines or previous outcomes.
- Collaborating with support staff to ensure documentation is complete before submission.
When physicians clearly explain the rationale behind their recommendations, it increases the likelihood of quick approval and prevents time-consuming follow-up requests from payers.

Medical Assistants Compile Records
Once the physician initiates the request, medical assistants or nurses take over much of the background work. Their role is to ensure the insurer receives all supporting information needed to review the authorization.
Typical tasks include:
- Gathering recent test results, imaging reports, or lab data.
- Ensuring the diagnosis and procedure codes are accurate.
- Preparing any referral or supporting letters.
- Uploading documentation into the correct system or portal.
These staff members act as the bridge between clinical and administrative functions. A missing document or incorrect code can delay approval for days – so accuracy and thoroughness are crucial. Standardizing templates and maintaining organized records can make this stage much faster and less prone to errors.
Billing Staff Manage Insurance Portals
The billing or administrative team is the engine that drives the green prior authorization process forward. Once all documentation is ready, they handle submission through the insurer’s preferred channel – whether it’s an online portal, fax, or integrated electronic health record (EHR) system.
Their key responsibilities include:
- Submitting the request: Uploading all documentation, forms, and codes into the insurer’s system.
- Tracking progress: Monitoring each request’s status, checking for updates, and ensuring deadlines are met.
- Following up: Communicating with payers for additional information or clarification.
- Managing denials or appeals: If an authorization is rejected, the billing team coordinates resubmission with added documentation or justification.
Because most insurers have different requirements, experienced billing teams develop payer-specific checklists to ensure no detail is missed. Some healthcare practices even employ dedicated prior authorization specialists to oversee this part of the workflow exclusively.

Payers Review and Respond
Once the request is submitted, the responsibility shifts to the insurance company (payer). Their review process focuses on determining whether the requested service meets medical necessity criteria, aligns with plan coverage, and adheres to clinical guidelines.
Here’s what typically happens behind the scenes:
- The insurer’s utilization management department reviews the request.
- A medical director or nurse reviewer compares the documentation with established policy criteria.
- The payer issues one of three outcomes: approval, denial, or a request for additional information.
- Approved authorizations are assigned reference numbers and communicated back to the provider’s office.
Response times vary – some approvals take a few hours, while others stretch into several days. Having a strong communication system in place between the provider’s staff and the insurer helps prevent bottlenecks. When denials occur, they can be appealed, but only if all previous steps were well-documented.

Conclusion
Successful green prior authorization management depends on coordination, accuracy, and communication across every team involved. From physicians identifying medical necessity to medical assistants preparing documentation and billing staff managing submissions, each step builds on the one before it.
A well-structured workflow reduces delays, prevents denials, and ensures patients receive timely care. Providers who invest in staff training, automation tools, or professional outsourcing see significant improvements in turnaround time and approval rates.
