Critical care medicine specialists play a pivotal role in diagnosing and treating a wide array of severe illnesses. Given the complexity of caring for critically ill patients, a multidisciplinary team approach is essential. However, billing for critical care services involves dealing with complex rules and regulations to ensure accurate reporting on claims. As a critical care provider, staying abreast of these guidelines is paramount to guaranteeing proper reimbursement and conveying the intensity of care provided.
Medicare’s guidelines now align with the Current Procedural Terminology (CPT) definition of critical care, emphasizing the care of critically ill or injured patients with acute impairment of vital organ systems. This care demands complex decision-making to address organ failure and prevent life-threatening deterioration. Notably, critical care services may be administered by both physicians and non-physician practitioners (NPPs), such as nurse practitioners (NPs) and physician assistants (PAs).
Critical care services are time-based and require meticulous documentation of the total time spent delivering direct critical care to the patient. CPT codes 99291 and 99292 are used to report these services, with specific guidelines based on the duration of care provided. It’s crucial to accurately report the time spent on critical care, excluding time dedicated to separately reportable procedures or services.
Several services are bundled into critical care, making them not separately payable when furnished concurrently with critical care. These include interpretation of cardiac output measurements, chest X-rays, pulse oximetry, and ventilator management, among others.
Billing for critical care services involves several key considerations to ensure accurate reporting and reimbursement. Below are essential points to understand when billing for critical care services:
Critical care services span multiple days and are typically administered in dedicated critical care areas. During the provision of critical care, practitioners cannot attend to other patients simultaneously. Therefore, billing and coding for critical care services and other evaluation and management (E/M) visits on the same calendar date is possible if distinct and separate services are rendered and supported by comprehensive documentation.
