Prior Authorization Challenges in Orthopedic Practices

Do you know that an orthopedic surgeon may receive, on average, $1,542.32 as an individual payment for their services? While this may seem a lot for a single surgical procedure, immense effort and paperwork are required for the orthopedic surgeon to claim it. One such hurdle that the specialists must hop over on their path to revenue collection is obtaining prior approval from the insurance payer for the surgery, also known as prior authorization.

Prior authorization challenges are far more complex and can take a toll on the professionals. 

But what are these challenges, and how do they impact the healthcare system? Don’t know the answer? Don’t worry, we’ve got you covered.

A Quick Overview of Prior Authorization

Every orthopedic practice understands what prior authorization is and why it is necessary. But for those who don’t, it is provided by an insurance payer. It is a “green light” for complex procedures that insurance payers may not always cover. 

Significance of Prior Authorization in Medical Billing 

Think of prior authorization as a first-tier clearance, where the orthopedic surgeon gets prior approval from the payer to check whether the procedure he intends to perform on the patient is covered and will be reimbursed. If the payer issues a pre-authorization letter, approving the service, the surgeon gets the go-ahead he was looking for. Later, he must attach this pre-authorization letter as a supporting document to remind the payer that the service was pre-approved and hence, qualifies for reimbursement. In simple words, pre-authorization acts as a cost-control mechanism in an orthopedic practice’s revenue cycle.  

Prior Authorization Delays and Impact 

While prior authorization is important and sought quite often in orthopedic practices, it is not as easy to obtain. Sometimes, it can take up to 15 business days to get the payer’s approval for an orthopedic surgery. 

Without prior authorization, professionals may not be able to treat patients right away, which can significantly disrupt care and prolong recovery time. In more serious cases, delays in approvals can also lead to permanent disability in patients because of delayed treatment. 

For instance, procedures like hip replacement require urgent attention, and without pre-authorization, orthopedics cannot begin treatment. 

Reasons for Prior Authorization Delays in Orthopedic Practices

Getting prior authorization in an orthopedic practice should not feel like an obstacle course, but unfortunately, this can be the case in several scenarios. Any medical facility at any given time can have queues of patients awaiting medical treatment. 

Additionally, staff shortages further contribute to delays, particularly when third-party approval is involved. Here are some basic reasons that lead to prior authorization challenges in ortho practices:

Complex & Costly Medical Procedures

Ortho treatments involve high-cost diagnostic imaging (MRIs and CT scans) and complex surgical procedures. The payer doesn’t mind pre-approving and covering these services. However, they must be given proof of medical necessity. For example, in his request for prior approval, the surgeon must explain the patient’s condition and symptoms (e.g., persistent and severe back pain), why conservative treatment options failed, and how the surgery will help achieve treatment goals. 

These comprehensive reviews to assess the medical necessity of complex, high-cost, and elective procedures cause delayed approval.

High Authorization Request Volume

Most non-emergency/elective orthopedic surgeries require prior approval. Due to this, payers often have to deal with request backlogs. Moreover, complex cases require peer-to-peer review, so this further delays the attainment of prior authorization in orthopedic practices. 

Documentation Rule Changes

The pre-authorization requirements for certain outpatient services might change from time to time. Orthopedics who are not fully aware of the latest changes may forward incorrect requests with incomplete documentation, resulting in authorization delays or denials.

Orthopedic Prior Authorization Changes

Considering the prior authorization challenges in ortho practices, here are some changes that orthopedics should stay mindful of:

Switching to Electronic

The Centers for Medicare and Medicaid Services (CMS)’s Interoperability and Prior Authorization Final Rule (CMS-0057-F) now applies to billing and pre-authorizations. Orthopedic professionals and practices must now submit pre-authorization requests electronically to speed up the process.

According to this rule, insurers, such as Medicare Advantage and Medicaid, must adopt FHIR-based API technology to streamline prior approvals. Therefore, faxing authorization requests is no longer applicable. 

Approvals for Specialty Medicines

Orthopedics now must obtain pre-authorization for more procedures and treatments. For instance, treatments involving specialty medicines and biologics must also be approved in advance. An example of this is Blue Cross Blue Shield of Illinois‘ changes to the Pharmacy Prior Authorization program, which became effective on June 15, 2025.

Orthopedic Procedures with Complex Authorization Processes

The following are some of the orthopedic services and procedures that require the payer’s prior approval:

• Spinal surgeries
• Radiology and diagnostic tests
• Pain management injections
• Long-term medication treatments
• Knee replacements
• Joint arthroscopy
• Intra-articular injections
• Hip replacements

Note: Many treatments and specialty medications may require advance approvals. Therefore, we recommend checking the latest requirements for prior authorization.

Common Reasons for Orthopedic Prior Authorization Denials

Orthopedic prior authorization may be denied for several reasons. Here’s a quick breakdown of the most common ones:

A Lack of Medical Necessity

Medical necessity explains why the patient needs the treatment or procedure. This necessity can be explained by submitting previous medical reports or current scans. If the billing team provides insufficient documents and cannot prove medical necessity, it results in an authorization denial. 

Therefore, the documents provided should clearly outline the patient’s current medical condition and why a procedure or treatment is needed.

Incorrect Diagnosis or Coding

Diagnosis errors or entering incorrect codes in the request from are another common reason for prior authorization rejections in orthopedic practices. For example:

• The billing team uses outdated ICD-10 codes.
• If a lack of specificity in diagnosis coding is found
• If there is a mismatch between diagnosis and procedure codes.

The best way to avoid such prior authorization challenges is to train the staff regarding ICD-10 coding. Moreover, ensuring every pre-authorization request is backed with sufficient documentation and setting up a diagnosis code verification system are smart ways to avoid such errors. 

Out-Of-Network Provider

An orthopedic service provider’s pre-authorization request may also be denied if they are not part of the insurance payer’s network, i.e., they are an out-of-network provider and not eligible for reimbursement. 

Tips to Counter Prior Authorization Challenges in Ortho Practices

Pre-authorization challenges in ortho practices can lead to several complications and treatment delays for patients. Therefore, here are some additional tips for successful approvals:

Add Smart Review Systems

Incomplete symptom descriptions and mismatched codes often result in request denial, and a single review can save billing teams. Therefore, we recommend using a smart review system that can detect errors in pre-authorization forms and supporting documents. This way, orthopedics can avoid bottlenecks and streamline the process.

Reach Out to Experts

Some pre-authorization requests are too complex to be handled independently. For instance, the billing team may not be aware of the latest changes in the documentation requirements or payer-specific details. 

This can be fairly intimidating for first-time medical billers, which is why some providers outsource medical billing services to third-party companies.

Use Orthopedic-Specific Templates 

Using standardized forms for prior authorization in orthopedic practices can fast-track the process because, instead of creating requests from scratch, staff can swiftly enter the key details and submit the form for approval. Moreover, the templates could be categorized into two: one for emergency approvals (24 to 72 hours) and another for elective procedures (7 to 15 business days).
