Comprehensive Orthopedic Billing Services for Maximizing Reimbursement
Orthopedic billing can be complex due to the variety of services offered, including surgeries, rehabilitation, physical therapy (PT), and occupational therapy (OT). Our experience spans joint replacements, fracture care, arthroscopy, and sports medicine procedures. Our billing experts ensure that every detail is captured accurately, from pre-operative care to post-operative follow-up, maximizing your practice’s revenue while minimizing denials.
Nuances in Orthopedic Billing
Orthopedic billing covers a broad spectrum of procedures and services, each with its own unique coding and documentation requirements. Some of the key challenges include:
Surgical Procedures:
Orthopedic surgeries, such as joint replacements or arthroscopies, require precise coding to reflect the complexity of the surgery, the use of implants, and the specific anatomical site.
Rehabilitation Services (PT/OT):
Billing for physical therapy and occupational therapy involves coding for the treatment plan, therapy modalities, and ongoing patient progress. It's essential to ensure that the therapy is deemed medically necessary and is well-documented.
Fracture Care:
Billing for fracture management can vary depending on whether the treatment is operative or non-operative. Appropriate modifier usage and ensuring the global billing period is accounted for are crucial in getting the claims reimbursed correctly.

Medical Necessity in Orthopedic Billing
Medical necessity is critical when billing for orthopedic services, particularly surgeries, rehabilitation, and injections. Clear documentation is essential to prove the necessity of the procedure or therapy to the insurance payers. For example, the justification for a total knee replacement must include evidence of failed conservative treatments (e.g., physical therapy, pain management) and significant patient symptoms like decreased mobility and severe pain.
