Illinois Payer Guidelines & LCD Policy Coverage

Clinical providers in Illinois submit Part B Medicare claims governed by National Government Services (NGS) (Jurisdiction 6 (J6)). Millennova Solution embeds region-specific Local Coverage Determinations (LCDs) and Local Coverage Articles (LCAs) directly into our pre-bill scrubbing rules. We protect high-complexity orthopedic, spine surgery, interventional pain, and anesthesia claims from improper downcoding, cross-year filing rejections, and commercial payer underpayment.
