Expert Guidance on Critical Care Billing Services and CPT Code

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.

Scope of Critical Care Services

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).

Reporting Critical Care Services

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.

Services Included in Critical Care

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 Critical Care Services – Key Points

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:

1. Nature of Critical Care: Critical care services often necessitate the undivided attention of the practitioner and are typically provided in dedicated critical care areas like intensive care units or emergency departments.
2. Time-Based Billing: Critical care services are billed based on the total duration of direct care provided to the patient. It's crucial to accurately document the time spent delivering critical care, excluding time dedicated to other procedures or services.
3. Continuous Care: Critical care services can span multiple days, and if provided continuously beyond midnight, the total time is reported without interruption. However, any interruption in service requires reporting a new initial service.
4. Billing for Concurrent Services: If a patient receives both critical care services and another evaluation and management (E/M) visit on the same calendar date, billing for both services is possible if they are distinct and supported by comprehensive documentation. Modifier 25 may be appended to the hospital visit codes in such cases.
5. Concurrent Care by Multiple Providers: Concurrent critical care services can be provided by multiple practitioners of different specialties, as long as each plays an active role in the patient's treatment and services are medically necessary.
6. Split/Shared Services: Critical care visits may be furnished as split/shared visits between a physician and an NPP. The reporting provider must have performed over 50% of the total time spent, and modifier FS should be added to the critical care code on the claim.
7. Separate Payment: Critical care services can be separately paid in addition to a procedure with a global surgical period if the critical care is unrelated to the procedure. Proper documentation is essential to indicate the separate nature of the critical care service.
8. Modifiers: Modifiers such as 24 (Unrelated evaluation and management service) or FT (Unrelated evaluation and management visit) may be used when billing critical care services to indicate the critical care's relationship to other services or procedures.
9. Medical Record Documentation: Comprehensive documentation is imperative when reporting critical care services, including details of services performed, total time spent, and the distinct role of each specialty involved in patient care.

Important to Note:

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.
