Final answer:
Outpatient facilities should pay particular attention to the Federal Register editions published in November or December since they contain the final rules for OPPS and ASC payment systems, which are crucial for their operations and compliance.
Step-by-step explanation:
The edition of the Federal Register that outpatient facilities would be especially interested in is typically the one published in November or December. This is because the Centers for Medicare and Medicaid Services (CMS) often release the final rule for the Outpatient Prospective Payment System (OPPS) and the Ambulatory Surgical Center (ASC) payment system for the upcoming year during this time. These rules include important information about billing, reimbursement rates, and policy changes that directly affect the financial and operational aspects of outpatient facilities. Keeping up-to-date with this information is essential for outpatient facilities to ensure compliance and optimal financial performance.
