Critical care coding is a critical component of medical billing, especially within hospital settings. It involves specific codes (99291 and 99292) used to bill for intensive care services provided to patients facing life-threatening conditions. Understanding exactly What Is Included In Critical Care Coding is essential for healthcare providers to ensure accurate billing and appropriate reimbursement. This guide breaks down the key elements of critical care coding, helping you navigate the complexities and optimize your billing practices.

Bundled Services Within Critical Care Codes (99291-99292)
When you bill using critical care codes, it’s crucial to understand that certain procedures are considered bundled into these codes according to CPT (Current Procedural Terminology) guidelines. This means you cannot bill separately for these services when they are performed as part of critical care. Knowing what’s included prevents billing errors and maximizes appropriate revenue.
Here’s a breakdown of services typically bundled into critical care codes:
- Cardiac Output Measurements (93561, 93562): Monitoring the heart’s efficiency is often integral to managing critically ill patients.
- Chest X-rays (71010, 71015, 71020): Routine chest imaging to assess lung conditions and monitor treatment progress in critical cases.
- Pulse Oximetry (94760, 94761, 94762): Continuous monitoring of blood oxygen saturation, a fundamental aspect of critical care management.
- Blood Gases and Data Storage (99090): Analyzing arterial or venous blood gases to assess respiratory and metabolic status, along with associated data management.
- Gastric Intubation (43752, 91105): Insertion of a tube into the stomach for feeding, drainage, or medication administration, often necessary in critical care.
- Temporary Transcutaneous Pacing (92953): Non-invasive pacing to temporarily regulate heart rhythm in emergency situations.
- Ventilator Management (94002-94004, 94660, 94662): Managing mechanical ventilation for patients with respiratory failure, a core element of critical care.
- Vascular Access Procedures (36000, 36410, 36415, 36594, 36600): Establishing intravenous or arterial lines for medication delivery, fluid resuscitation, and hemodynamic monitoring.
It’s important to note that this list is not exhaustive, and CPT guidelines should always be consulted for the most up-to-date information. However, understanding these commonly bundled services is a crucial first step in accurate critical care coding.
Separately Billable Procedures During Critical Care
While many services are bundled, not everything performed during critical care is included in codes 99291-99292. Procedures performed that are distinct and separately identifiable from the critical care services themselves can be billed in addition to the critical care codes.
Examples of procedures that are often separately billable in life-threatening situations include:
- Cardiopulmonary Resuscitation (CPR) (92950): Emergency intervention for cardiac arrest, a significant and distinct procedure.
- Endotracheal Intubation (31500): Placement of a breathing tube into the trachea, a critical and separately identifiable procedure.
- Lumbar Puncture (62270): Spinal tap, a diagnostic or therapeutic procedure that is distinct from routine critical care.
- Central Venous Line Insertion (codes vary): Placement of a central line for long-term vascular access, a procedure separate from the ongoing critical care management.
When billing for these and other separately billable procedures alongside critical care, it is essential to document the critical care time separately from the time spent performing the procedure. Furthermore, using the modifier -25 appended to the Evaluation and Management (E&M) code (critical care code in this case) is crucial. Modifier -25 indicates that a significant, separately identifiable E&M service was performed on the same day as another procedure by the same physician.
Time is of the Essence in Critical Care Coding
A fundamental requirement for billing critical care codes is the time spent providing critical care services. According to coding guidelines, at least 30 minutes of critical care must be provided on a given date to bill code 99291 (the first 30-74 minutes). For each additional 30 minutes beyond the first 74 minutes, code 99292 can be billed.
When documenting critical care time, it’s recommended to be specific and avoid vague terms like “direct care.” Instead, a clear statement such as “I spent [X] minutes on critical care services, minus any separately billable procedures” is advisable. This documentation clearly demonstrates the time dedicated to critical care management and accounts for any procedures billed separately.
If the total critical care time on a given day is less than 30 minutes, you cannot bill critical care codes. In such cases, you would need to use regular Evaluation and Management (E&M) service codes appropriate for the level of care provided.
Discharge Coding Considerations in Critical Care
Critical care often involves complex discharge planning, especially when multiple physicians are involved in the patient’s care. A common scenario involves one hospitalist preparing the discharge summary and another finalizing the discharge on a subsequent day.
In such cases, only one physician within the same group (billing under the same tax ID) can bill for the discharge service. It is recommended that healthcare groups establish internal compliance policies outlining how discharge planning responsibilities are divided and which physician will bill for the discharge code (e.g., 99239 for a high-level discharge).
Typically, the physician who finalizes the discharge and documents the total duration of discharge service time should be the one billing the discharge code. If the patient’s discharge is delayed unexpectedly, the discharge service code should be disregarded, and an appropriate level of subsequent hospital visit code (99231-99233) should be billed for that day instead.
Conclusion
Accurate critical care coding hinges on a clear understanding of what services are bundled, what can be billed separately, and the crucial role of time documentation. By focusing on what is included in critical care coding, healthcare providers can ensure compliant and optimized billing practices. For further clarification and specific scenarios, resources like the American College of Emergency Physicians (ACEP) Critical Care FAQ can provide valuable guidance. Remember, precise documentation and a thorough understanding of coding guidelines are your best tools for navigating the complexities of critical care billing.
