What are the most common billing pitfalls in Texas orthopedic and spine surgery?
Orthopedic and spine surgical billing suffers high denial rates due to complex National Correct Coding Initiative (NCCI) unbundling edits, aggressive commercial payer bundling rules, and improper use of modifiers (-59, -XS, -58, -78, -79). Major surgical procedures carry a 90-day global surgical period during which routine postoperative visits cannot be billed separately. Additionally, moving procedures from Hospital Outpatient Departments (HOPD) to Ambulatory Surgical Centers (ASCs) requires verifying that the CPT code is on the payer-approved ASC covered procedure list and obtaining facility-specific pre-authorizations.
1. Conquering the 90-Day Global Surgical Package
Major orthopedic procedures (total knee arthroplasty 27447, total hip arthroplasty 27130, lumbar spinal fusion 22612) carry a 90-day global period.
Any postoperative encounter for surgical wound checks, staple removal, or routine healing cannot be billed. However, if a patient returns for an unrelated issue (e.g., contralateral joint pain), bill with modifier -24 accompanied by distinct ICD-10 diagnostic codes.
2. ASC versus HOPD Reimbursement Dynamics in Texas
Optimizing facility and professional revenue streams
As more spine and joint replacement surgeries shift to outpatient surgery centers, Texas orthopedic surgeons with ASC ownership must synchronize professional (CMS-1500) and facility (UB-04) billing.
Facility implants and expensive instrumentation often require invoice cost attachment or specific revenue codes (e.g. Rev Code 0278 for medical implants) to ensure full cost recovery.
