Summary & Overview
CPT 99485: Supervision of Pediatric Critical Care Transport (≤24 months)
CPT code 99485 represents physician supervision of the transport of a critically ill or injured child aged 24 months or younger for up to 30 minutes. The code captures pre-transport, in-transit, and post-arrival communication with the transport team and interpretation of patient data. This service is distinct from bedside critical care and documents the physician’s supervisory and consultative role during short-duration interfacility pediatric transports.
This publication addresses national implications for billing and coverage of CPT code 99485. Key payers considered are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context, typical sites of service, common modifiers used with transport and supervision services, and where to find related coding guidance. The piece also outlines what to expect in payer coverage policies and benchmark considerations for hospitals and transport teams when documenting supervisory involvement.
The article provides practical policy and billing context without state-specific detail. It includes benchmarks, policy updates, and coding notes that clarify how this supervision code fits alongside other critical care and transport services. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A critically ill or injured infant age 24 months or younger requires interfacility transfer from a community hospital to a pediatric tertiary care center for advanced care. Example scenario: a 6-month-old with respiratory failure from bronchiolitis requiring escalation to pediatric intensive care and possible mechanical ventilation. The PICU attending physician at the receiving center is contacted before transport, reviews the infant's clinical status and monitoring data with the sending team and transport crew, and provides oversight of resuscitation and stabilization measures. During the ground or air transport (duration up to 30 minutes under this CPT description), the receiving physician communicates with the transport team, interprets transmitted patient data (vital signs, oxygenation, ventilator parameters, bedside glucose, point-of-care labs), and advises clinical interventions. Upon arrival at the receiving facility the supervising physician receives a handoff, verifies patient status, and documents involvement in the supervised transport. Typical workflow includes pre-transfer discussion and acceptance, real-time remote supervision during transport, and arrival/handoff documentation in the receiving facility medical record. Typical site of service is interfacility transport (ground ambulance or air transport) between acute care hospitals, with the receiving physician usually located at the tertiary pediatric hospital (PICU or ED). Service type: Interfacility critical care transport supervision for infants (physician supervision).
