Summary & Overview
CPT 94775: Home Apnea Monitor Attachment and Recording (Technical Component)
CPT code 94775 documents the technical component of home-based pediatric apnea monitoring: attaching a monitor, programming it to record over a defined period, and disconnecting the patient at the end of the recording interval. This code is reported once per each 30-day period and applies to the technical services provided in the patient’s home. Nationally, home apnea monitoring for infants and children is an important component of pediatric respiratory and sleep-related care and has implications for remote patient monitoring workflows and durable medical equipment coordination.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code’s clinical role and billing scope, typical sites of service, and which stakeholders are relevant for coverage and claims processing. The publication outlines common modifiers associated with the technical component and notes areas where input data are not provided, such as associated taxonomies, ICD-10 diagnoses, and related codes. This summary equips clinicians, billing staff, and policy analysts with the core facts needed to identify when 94775 is the appropriate technical-service code for home apnea monitor setup and removal.

Clinical & Coding Specifications
Clinical Context
A 4-month-old infant with a history of apparent life-threatening events (ALTE) and suspected central or obstructive apnea is discharged home with a provider-attached, single-channel or multi-parameter apnea monitor. The clinician trains the caregiver on safe monitor use, attaches the monitor in clinic or at bedside, programs the device to record respiratory effort, heart rate, and oxygen saturation over a 30-day period, and documents the device serial number and settings. After the 30-day recording interval (or earlier if clinically indicated), the family returns the monitor to the clinic or the clinician visits the home to disconnect the patient and retrieve recorded data. The provider downloads, reviews, and incorporates the technical data into the medical record; interpretation and formal reporting of the data by a physician or qualified professional (when performed) is reported separately. Typical site of service is an outpatient clinic, pediatric sleep center, or the patient’s home with a clinic visit for attachment and removal. This code represents the technical component only and is billed once per each 30-day time period when the provider both attaches and later disconnects the home apnea monitor.
