CPT Coding Guidelines for Pediatric and Pediatric-Adult Transition CPAP

CPT Coding Requirements for Pediatric CPAP Devices and Supplies

• CPAP masks for pediatric patients are typically smaller and have unique designs compared to adult masks. The CPT code for a pediatric CPAP mask should accurately reflect its size and style. The E0613 code is used for pediatric CPAP masks for patients weighing less than 10 kg, while the E1393 code is used for pediatric CPAP masks for patients weighing at least 10 kg but less than 20 kg.
• Pediatric CPAP devices with a built-in humidifier require a specific CPT code. The E1398 code is used for pediatric CPAP devices with a built-in humidifier.
• Pediatric CPAP supplies, such as CPAP tubing and headgear, should be coded separately. The CPT code for a pediatric CPAP tubing set is E1399, while the CPT code for pediatric CPAP headgear is E1401.

Coding for Pediatric-Adult Transition CPAP Patients, Cpap machine cpt codes

• Pediatric patients transitioning to adult CPAP devices require specific CPT coding. The CPT code for an adult CPAP mask is E1393, while the CPT code for an adult CPAP tubing set is E1402.
