Critical care coding, especially in pediatrics, demands precision and a thorough understanding of specific guidelines. For healthcare providers and medical coders at carcodescanner.store, mastering pediatric critical care coding is essential for accurate billing and compliance. This article delves into the intricacies of Pediatric Critical Care Coding Guidelines, ensuring you can confidently navigate the nuances of CPT® and CMS regulations.
Understanding Critical Care Service Locations and Definitions
While critical care services are typically associated with specialized units like the Intensive Care Unit (ICU), Coronary Care Unit (CCU), or Emergency Department (ED), the location itself is not the determining factor for coding critical care. Critical care can be delivered in any setting, provided the services meet the defined criteria for critical care. Conversely, simply treating a patient within an ICU or NICU doesn’t automatically qualify the encounter as critical care. Routine checks, such as monitoring vital signs or noting the stable status of a ventilated patient, do not meet the threshold for critical care coding.
Key Performance Indicators for Pediatric Critical Care
To appropriately report pediatric critical care, specific Key Performance Indicators (KPIs) must be met. Both the patient’s illness or injury and the medical interventions provided must satisfy the requirements for critical care. For patients over 5 years old, meticulous clinical reassessments and detailed documentation are necessary to support the total critical care time billed. This documentation should include:
- Comprehensive records of the physician’s continuous evaluations of the patient’s condition.
- Documentation of organ system impairments, based on all relevant clinical data (e.g., metabolic changes and diagnostic findings).
- Clear rationale and timing for all interventions.
- Patient responses to the treatments administered.
Pediatric Critical Care Codes: Age-Based Categories
Pediatric critical care codes are categorized by the patient’s age, and these codes are reported on a per-day basis. If multiple providers from the same group or specialty attend to a patient under 5 years of age on the same day, only one critical care code can be billed for that day. The specific code sets are divided by age groups:
Neonatal Critical Care: 28 Days or Younger
99468 – Initial inpatient neonatal critical care, per day, for the evaluation and management of a critically ill neonate, 28 days of age or younger.
99469 – Subsequent inpatient neonatal critical care, per day, for the evaluation and management of a critically ill neonate, 28 days of age or younger.
Example Scenario:
Consider a newborn infant, born at term after an uncomplicated pregnancy and delivery, who presents with significant respiratory distress. The infant is admitted to the NICU, requiring intubation and mechanical ventilation. A neonatologist inserts an umbilical arterial line, and a subsequent chest X-ray reveals a pneumothorax, necessitating chest tube placement.
Correct Coding: 99468-25 (Initial inpatient neonatal critical care with modifier 25 for a significant, separately identifiable evaluation and management service) and 32551 (Tube thoracostomy, including connection to drainage system).
It’s important to note that procedures like endotracheal intubation (31500 – Intubation, endotracheal, emergency procedure) and umbilical artery catheterization (36660 – Catheterization, umbilical artery, newborn, for diagnosis or therapy) are bundled into code 99468. Modifier 25 is appended to 99468 to indicate a separately identifiable E/M service performed on the same day as another procedure.
Pediatric Critical Care: 29 Days to 24 Months
99471 – Initial inpatient pediatric critical care, per day, for the evaluation and management of a critically ill infant or young child, 29 days through 24 months of age.
99472 – Subsequent inpatient pediatric critical care, per day, for the evaluation and management of a critically ill infant or young child, 29 days through 24 months of age.
Example Scenario:
A former premature infant, born at 25 weeks gestation and now 45 days old, remains ventilator dependent. The infant’s condition deteriorates, showing increased ventilator needs and poor perfusion. Suspecting sepsis, the provider performs a bladder aspiration, lumbar puncture, obtains a blood culture, and initiates antibiotic therapy.
Correct Coding: 99472 (Subsequent inpatient pediatric critical care for infants aged 29 days to 24 months). Procedures like bladder aspiration and lumbar puncture are bundled into this critical care code.
Pediatric Critical Care: 2 to 5 Years
99475 – Initial inpatient pediatric critical care, per day, for the evaluation and management of a critically ill infant or young child, 2 through 5 years of age.
99476 – Subsequent inpatient pediatric critical care, per day, for the evaluation and management of a critically ill infant or young child, 2 through 5 years of age.
Example Scenario:
A 5-year-old girl is involved in a severe motor vehicle accident, suffering blunt trauma to her left side. Injuries include a splenic laceration, rib fractures, flail chest on the left, and acute respiratory failure.
Day 1 Coding: 99475 (Initial inpatient pediatric critical care).
On the second day, the child develops left chest infiltrates and pleural effusion, leading to respiratory arrest and requiring ventilation.
Day 2 Coding: 99476 (Subsequent inpatient pediatric critical care). All other services provided on this day are considered bundled into the critical care service.
For patients older than 5 years requiring critical care, time-based codes are utilized.
Critical Care for Patients Over 5 Years
99291 – Critical care, evaluation and management of the critically ill or critically injured patient; first 30-74 minutes.
+99292 – each additional 30 minutes (List separately in addition to code for primary service).
Accurate time documentation is crucial when using codes 99291 and 99292. Code 99291 is used for the initial 30-74 minutes of critical care, and +99292 is for each additional 30-minute increment beyond the first 74 minutes.
Table A: Time-Based Critical Care Coding
| Total Duration of Critical Care | Appropriate CPT® Codes |
|---|---|
| Less than 30 minutes | 99232, 99233, or other E/M code |
| 30 – 74 minutes | 99291 x 1 |
| 75 – 104 minutes | 99291 x 1 and 99292 x 1 |
| 105 – 134 minutes | 99291 x 1 and 99292 x 2 |
| 135 – 164 minutes | 99291 x 1 and 99292 x 3 |
| 165 – 194 minutes | 99291 x 1 and 99292 x 4 |
| 194 minutes or longer | 99291 – 99292 as appropriate |
For example, 76 minutes of critical care is coded as 99291. For 110 minutes, report 99291 and 99292 x 1. Critical care less than 30 minutes should be reported using appropriate ED, inpatient, or other relevant E/M codes.

CPT® and CMS Definitions of Critical Care
While both CPT® and CMS have definitions for critical care, some nuances exist. CPT® defines critical illness or injury as “an acute impairment of one or more vital organ systems such that there is a high probability of imminent or life-threatening deterioration in the patient’s condition.” Medical records must substantiate that these criteria are met, along with the physician’s confirmation that critical care was indeed provided.
CMS further specifies that the illness or injury must be of an urgent or emergent nature and necessitate high-level treatments and interventions to qualify as critical care.
CMS Critical Care Criteria Examples:
- Not Met: If only pharmacological intervention is prescribed by the emergency physician.
- Met: If acute interventions like intubation are necessary and performed.
- Not Met: If care is limited to coordination and study interpretation, followed by admission or discharge.
CMS provides further examples of situations that do not meet critical care criteria due to lack of medical necessity or if the patient’s condition does not constitute a critical illness or injury:
- Admission to a critical care unit solely due to bed unavailability elsewhere.
- Admission for routine nursing observation or frequent vital sign monitoring, such as in cases of drug toxicity or overdose.
- Admission due to hospital protocols requiring certain treatments, like insulin infusions, to be administered in the ICU.
Bundled Services in Critical Care Coding
Both CPT® and CMS include certain services as bundled into critical care time when performed during the critical care period by the same physician providing critical care. These services should not be reported separately.
Services Bundled into Codes 99291 and 99292:
- Interpretation of cardiac output measurements (93561, 93562)
- Pulse oximetry (94760, 94761, 94762)
- Chest X-rays, professional component (71010, 71015, 71020)
- Blood gases, and data stored in computers (e.g., ECGs, blood pressures, hematologic data – 99090)
- Gastric intubation (43752, 91105), transcutaneous pacing (92953)
- Ventilator management (94002-94004, 94660, 94662)
- Vascular access procedures (36000, 36410, 36415, 36591, 36600)
Additional Services Bundled into Pediatric Critical Care Codes (99468, 99469, 99471, 99472, 99475, 99476):
In addition to the services bundled in 99291-99292, pediatric critical care codes also bundle the following, which may be facility-reported only:
- Administration of blood/blood components (36430, 36440)
- Administration of intravenous fluids (96360-96361)
- Administration of surfactant (94610)
- Bladder aspiration, suprapubic (51100)
- Bladder catheterization (51701, 51702)
- Car seat evaluation (94780-94781)
- Catheterization umbilical artery (36660)
- Catheterization umbilical vein (36510)
- Central venous catheter, centrally inserted (36555)
- Endotracheal intubation (31500)
- Lumbar puncture (62270)
- Oral or nasogastric tube placement (43752)
- Pulmonary function testing, performed at the bedside (94375)
- Initial and subsequent care for a critically ill infant or child
- Other hospital or intensive care services by the same group or individual on the same day as initial neonatal/pediatric critical care
- Readmission to critical unit on the same day (subsequent care)
CMS extends the bundling timeframe to include the entire calendar day for which critical care is billed, unlike CPT®, which ties it to the critical care period itself.
Separately Reportable Services in Critical Care
When using time-based codes 99291-99292, the critical care time calculation pauses when performing separately billable procedures. While not exhaustive, common separately reportable procedures for patients over 5 years include:
- Cardiopulmonary resuscitation (92950)
- Endotracheal intubation (31500)
- Central line placement (36555, 36556)
- Intraosseous placement (36680)
- Tube thoracostomy (32551)
- Temporary transvenous pacemaker (33210)
- ECG with at least 12 leads with interpretation and report only (93010)
- Electrical cardioversion (92960)
- Services by a transferring individual before patient transfer to a different group (99221-99233, 99291-99292, 99460-99462, 99477-99480)
- Services by another group receiving a patient transferred to a lower care level (99231-99233, 99478-99480)
- Services by an individual transferring a patient to a lower care level (99231-99233, 99291-99292)
Example Scenario:
A neonatologist is asked to care for a 6-year-old boy in respiratory arrest. Over 90 minutes, she provides critical care, including endotracheal intubation and central line placement, to stabilize him.
Correct Coding: 99291, 99292, 31500, and 36556.
Because the patient is over 5 years old, time-based critical care codes are appropriate. Intubation (31500) and central line placement (36556 – Insertion of non-tunneled centrally inserted central venous catheter; age 5 years or older) are separately reportable as they are not bundled into time-based critical care codes.
Conclusion: Accurate Pediatric Critical Care Coding Through Detailed Documentation
Accurate reporting of critical care services, especially pediatric critical care, hinges on precise time documentation and a clear understanding of coding guidelines. Providers must meticulously document the total duration of critical care services in the medical record. Coders and billers then rely on this documentation to accurately extract and aggregate time to select the correct critical care codes. Proper documentation practices are paramount to ensure compliant and accurate billing for pediatric critical care services. For further information, refer to CMS MLN Matters® article MM5993.
