Prior Authorization Challenges for Orthopedic Surgeons
Orthopedic surgeons are no strangers to administrative complexity. From navigating payer rules to managing post-operative care, they operate at the intersection of clinical precision and regulatory burden. Among the most disruptive elements in this space is prior authorization — and in 2025, the challenge is intensifying.
Beginning December 15, 2025, the Centers for Medicare & Medicaid Services (CMS) will expand its prior authorization requirements for procedures performed in Ambulatory Surgical Centers (ASCs). While the stated goal is to reduce unnecessary utilization, the practical consequence for orthopedic surgeons is clear: more delays, denials, and revenue risk.
This article outlines what orthopedic practices need to know and how revenue cycle management (RCM) strategies can prevent financial and operational disruption.
CMS's Prior Authorization Expansion: What Orthopedic Surgeons Must Understand
Under the updated CMS demonstration model, a number of procedures commonly performed in ASC settings will require Medicare prior authorization. These include:
Botulinum toxin injections used in orthopedic care for conditions like post-stroke spasticity (CPT 64612, 64615; HCPCS J0585–J0589)
Vein ablation therapies for patients with chronic venous insufficiency, often seen in mobility-limited orthopedic populations (CPT 36473–36483)
Panniculectomy and related surgeries, which may follow trauma recovery or significant weight loss tied to musculoskeletal impairment (CPT 15830, 15847)
Though the CMS list includes a wide range of procedures across specialties, the orthopedic community is not exempt. Many orthopedic practices operate within multispecialty groups or ASCs where these procedures are performed, which places them squarely within the scope of the upcoming compliance requirements.
The Real Impact: Delayed Care and Lost Revenue
Prior authorization is not just a regulatory burden — it is a significant barrier to timely patient care and a growing threat to practice revenue. According to the American Medical Association (AMA):
94% of physicians report that prior authorization has caused delays in necessary care.
33% of physicians report that these delays have led to serious adverse events for patients.
85% describe the administrative burden of prior authorization as high or extremely high.

For orthopedic surgeons, whose care plans often include time-sensitive procedures, imaging, rehabilitation, and biologic therapies, these delays are particularly damaging. A postponed surgery does not simply inconvenience a patient — it can alter recovery timelines, increase downstream costs, and create lasting dissatisfaction with care.
The Financial Cost to Orthopedic Practices
Orthopedic procedures often involve high reimbursements and complex billing, which makes them especially vulnerable to prior authorization delays and denials. Consider the following scenario:
An orthopedic ASC performs 30 to 40 surgeries per week.
Approximately 25 percent of these procedures now fall under CMS’s prior authorization requirements.
If just five of those procedures are delayed or denied due to missing prior authorization, the practice could lose $50,000 to $75,000 in revenue per week.
These losses are compounded by the administrative cost of rescheduling, appealing denied requests, and recovering from downstream claim rejections. Additionally, surgical blocks are lost, and patient trust may be permanently eroded.
Common Prior Authorization Challenges in Orthopedic Settings
1. Scheduling Disruptions
Surgeries cannot proceed without approved authorizations. When approvals are delayed or forgotten, it forces last-minute cancellations, wastes operating room resources, and strains staffing schedules.
2. High Denial Rates
Missing documentation, inconsistent ICD-10 coding, and incomplete medical necessity language frequently lead to denials — even for clearly appropriate care.
3. Documentation Gaps
Orthopedic cases often involve nuanced clinical histories. Incomplete documentation or lack of evidence for failed conservative therapy is a leading cause of denied authorizations.
4. Lack of Real-Time Tracking
Without a centralized system for submission and status monitoring, practices struggle to keep up with authorization timelines and payer-specific rules.
A Strategic Solution: RCM Services Built for Orthopedic Workflows
Revenue cycle management firms play a crucial role in helping orthopedic practices navigate the increasing complexity of prior authorization. A proactive, tech-enabled RCM partner offers more than billing support — it becomes an extension of the clinical and administrative teams.
1. Automated CPT Code Flagging
An advanced RCM system can identify procedures from the CMS list or payer-specific requirements and flag them during the scheduling phase. This ensures that authorizations are never missed.
2. Seamless Pre-Authorization Workflows
Automation tools can submit prior authorization requests, attach documentation, and track approval status in real time. This reduces manual workload and shortens approval turnaround time — often by several days.
3. Clinical Documentation Optimization
Effective RCM partners provide templates and training for orthopedic providers to improve documentation. This includes aligning diagnoses with payer expectations and ensuring medical necessity is fully supported.
4. Denial Management and Appeals
When authorizations are denied, experienced RCM teams can analyze the root cause, resubmit with corrected documentation, and manage appeals with targeted payer strategies.
Preparing for December 15: What Orthopedic Surgeons Should Do Now
The CMS prior authorization expansion goes into effect in December 2025, leaving a narrow window for practices to assess and modernize their workflows. Orthopedic groups should:
Identify any overlapping procedures in their billing with the CMS prior auth list.
Train staff on documentation requirements and payer-specific submission guidelines.
Evaluate current denial rates and pre-auth turnaround times.
Implement or upgrade their prior authorization tracking tools.
Consider outsourcing authorization management to a specialized RCM partner.
Conclusion: Compliance is Critical, but Strategy Wins
The prior authorization process is no longer a clerical task. It is a strategic imperative for orthopedic surgeons operating in today's regulatory environment. With new CMS policies in place, failure to adapt will mean delayed care, denied revenue, and operational strain.
By partnering with a revenue cycle management team that understands the unique challenges of orthopedic practices, providers can protect their revenue, reduce staff burden, and ensure patients receive the care they need — without administrative barriers.
