Critical care coding is a specialized area within medical billing and coding, focusing on services provided to patients who are critically ill or injured. Accurate coding in this domain is paramount for healthcare providers to receive appropriate reimbursement and for healthcare systems to maintain financial stability. The year 2020 brought forth specific guidelines that healthcare professionals needed to adhere to for compliant and effective billing of critical care services. Understanding these guidelines is crucial for coders, billers, physicians, and healthcare administrators.
Understanding Critical Care Services
Critical care services are defined as the direct delivery by a physician(s) of medical care for a critically ill or critically injured patient. A critical illness or injury acutely impairs one or more vital organ systems such that there is a high probability of imminent or life-threatening deterioration in the patient’s condition. It involves high complexity decision making to assess, manipulate, and support vital organ system failure and/or to prevent further life-threatening deterioration of the patient’s condition.
Critical care and intensive care are often used interchangeably, although critical care is the professional service provided by physicians and other qualified healthcare professionals, while intensive care refers more broadly to the specialized care setting, such as an Intensive Care Unit (ICU).
Key Changes and Clarifications in 2020 Critical Care Coding Guidelines
The 2020 coding guidelines, primarily based on the Current Procedural Terminology (CPT) codes and guidelines set forth by the American Medical Association (AMA) and further interpreted by the Centers for Medicare & Medicaid Services (CMS), introduced several important clarifications and changes. These updates aimed to enhance coding accuracy and reflect the evolving nature of critical care medicine. While some guidelines remain consistent, staying abreast of annual updates is essential.
Time-Based Coding for Critical Care
A fundamental aspect of critical care coding is its time-based nature. Critical care codes 99291 and 99292 are used to report the total duration of time spent by a physician or qualified healthcare professional actively providing critical care services to a critically ill or injured patient. The 2020 guidelines reiterated that this time must be devoted exclusively to the critical care patient, either at the bedside or immediately available in the critical care unit.
Code 99291 is used for the first 30-74 minutes of critical care on a given date, while 99292 is used for each additional 30 minutes. It’s crucial to accurately document the total time spent delivering critical care, as this documentation directly supports the billed codes. The time can be continuous or accumulated throughout the calendar day.
What Counts as Critical Care Time?
The 2020 guidelines clarified what activities can be included in critical care time. This includes:
- Reviewing patient history and medical records: Time spent reviewing pertinent information directly related to the patient’s critical condition.
- Performing physical examinations: Focused assessments relevant to the critical illness or injury.
- Ordering and evaluating diagnostic tests: Time spent ordering, reviewing, and interpreting tests such as lab work, imaging, and cardiac studies.
- Formulating treatment plans: Developing and adjusting the patient’s plan of care to address their critical needs.
- Discussions with other healthcare professionals: Consultations with nurses, respiratory therapists, specialists, and other members of the care team directly involved in the patient’s critical care.
- Family conferences: Discussions with the patient’s family members or surrogates to discuss the patient’s condition, prognosis, and treatment options, when these discussions are aimed at making treatment decisions.
It is important to note that time spent performing separately reportable procedures should not be included in critical care time. For example, time spent performing endotracheal intubation or central line placement is billed separately and is not part of the critical care time calculation.
Exclusions from Critical Care Time
Certain activities are specifically excluded from critical care time, according to the 2020 guidelines. These exclusions are crucial for accurate coding and to avoid overbilling. Excluded activities include:
- Time spent on separately reportable procedures: As mentioned earlier, procedures that have their own CPT codes, such as intubation (31500) or chest tube insertion (32551), are not included in critical care time.
- Travel time: Time spent traveling to the patient’s location or between different locations is not considered critical care time.
- Time spent by non-physician staff: Only the time spent by the physician or qualified healthcare professional providing critical care can be counted. Time spent by nurses or other staff members, while crucial for patient care, is not included in the physician’s critical care time.
- Teaching activities: Time spent teaching residents or medical students, if primarily for educational purposes and not direct patient care, is generally excluded.
Documentation Requirements for Critical Care
Robust documentation is the cornerstone of compliant critical care coding. The 2020 guidelines emphasize the necessity of clear, concise, and comprehensive documentation to support the level of critical care services billed. Key elements of documentation include:
- Patient’s critical illness or injury: Clearly state the acute illness or injury that meets the definition of critical illness, including the organ systems involved and the probability of life-threatening deterioration.
- Medical necessity for critical care: Document why the patient’s condition required critical care interventions and monitoring.
- Detailed description of services provided: Outline the specific critical care services delivered, including assessments, interventions, and management decisions.
- Total time spent providing critical care: Accurately record the start and stop times, or total cumulative time, spent on critical care activities. The documentation should clearly support the total time reported for codes 99291 and 99292.

Critical Care and Global Surgical Packages
The 2020 guidelines also address the relationship between critical care services and global surgical packages. Critical care services provided during the global period of a surgery may be separately reportable under specific circumstances. If the critical care service is unrelated to the surgical procedure for which the global period applies, and it meets the criteria for critical care, it can be billed separately with modifier -25 appended to the appropriate Evaluation and Management (E/M) code. Proper documentation is essential to support the separate billing of critical care within a global period.
Critical Care for Neonates and Pediatric Patients
Specific coding guidelines exist for critical care services provided to neonates (newborns) and pediatric patients. While the general principles of critical care coding apply, there are distinct code sets (99468-99476) and specific guidelines tailored to the unique needs and complexities of caring for critically ill newborns and children. The 2020 updates reinforced the importance of using the appropriate code sets based on the patient’s age and the specific services provided.
Navigating the 2020 Guidelines for Accuracy
Successfully navigating the 2020 critical care coding guidelines requires ongoing education, meticulous documentation practices, and a thorough understanding of both CPT and payer-specific requirements. Coding professionals and healthcare providers should:
- Stay updated: Continuously monitor updates and revisions to coding guidelines released by the AMA and CMS.
- Provide comprehensive documentation: Ensure all medical records accurately and completely reflect the critical nature of the patient’s condition and the critical care services provided.
- Seek clarification: When uncertain about coding scenarios, consult with coding experts, professional organizations, or payer representatives for guidance.
- Conduct regular audits: Perform periodic audits of critical care coding and billing practices to identify and address potential areas of non-compliance or inaccuracy.
By adhering to the 2020 critical care coding guidelines and maintaining vigilance in coding practices, healthcare organizations can ensure accurate reimbursement, reduce claim denials, and support the financial viability of critical care services. These guidelines are not merely about billing; they are about accurately representing the complex and vital care provided to the most vulnerable patients.
