Summary & Overview
HCPCS C1742: Implantable Intramuscular Continuous Pressure Monitoring System
HCPCS Level II code C1742 represents an implantable, compartmental intramuscular pressure monitoring system designed for continuous physiologic pressure measurement and includes all physical components but excludes mobile (wireless) software applications. This device-level code matters nationally as it captures billing for advanced implantable monitoring technology used in surgical and post-surgical management where continuous intramuscular pressure data are clinically relevant.
Payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for the device, typical sites of service, and the implications for coding and billing workflows. The publication summarizes expected service types tied to the code, common modifiers associated with device and procedure reporting, and outlines where to look for payer-specific coverage policies and reimbursement guidance.
The report presents practical benchmarks where available, notes gaps in public coverage statements, and highlights areas for policy attention such as implantable device classification, bundled payment considerations, and outpatient monitoring follow-up. Data not available in the input will be explicitly labeled where relevant.
Billing Code Overview
HCPCS Level II code C1742 describes a pressure monitoring system, compartmental intramuscular (implantable), continuous, including all components (for example, introducer and sensor). The description explicitly excludes mobile (wireless) software applications.
Service Type: Implantable continuous intramuscular pressure monitoring device placement and related equipment.
Typical Site of Service: Inpatient hospital operating room or ambulatory surgical center for device implantation, with potential subsequent outpatient device checks or monitoring visits.
Data not available in the input.
Clinical & Coding Specifications
Clinical Context
A 58-year-old male patient with a history of compartment syndrome following a tibial fracture undergoes implantation of a continuous intramuscular compartmental pressure monitoring system (C1742) to allow real-time surveillance of intracompartmental pressures in the anterior compartment of the lower leg. The implantable sensor system is placed in the operating room under monitored anesthesia care or general anesthesia. Preoperative steps include imaging review and consent; intraoperative steps include sterile preparation, incision, creation of a small intramuscular pocket, introducer placement, sensor deployment, securement of the lead and device, confirmation of sensor position, and wound closure. Postoperative workflow includes device interrogation, calibration, documentation of baseline pressure readings, patient recovery in PACU, device education for the care team, and scheduled outpatient follow-up for incision check and remote or in-clinic interrogation of the implanted sensor. Typical indications include suspected or recurrent compartment syndrome, traumatic extremity injury with high risk for elevated compartment pressures, or ongoing monitoring after fasciotomy when continuous compartment pressure data informs further care decisions. Typical site of service is an inpatient or ambulatory surgical center procedure performed in the operating room or procedure suite. Common payors include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
