Summary & Overview
HCPCS Level II C1785: Pacemaker, Dual Chamber, Rate-Responsive (Implantable)
HCPCS Level II code C1785 designates an implantable dual-chamber, rate-responsive pacemaker. These devices are central to managing a range of bradyarrhythmias and conduction disorders and have substantial implications for surgical services, device supply costs, and long-term cardiac care. Nationally, pacemaker implantation volumes and device selection affect hospital revenue cycles and Medicare spending for cardiac device therapy.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and typical sites of service, plus national benchmarking of reimbursement and utilization patterns where available. The publication covers coding and billing considerations tied to the device descriptor, payer coverage trends, and common clinical scenarios that prompt implantation.
The report is organized to help billing, revenue cycle, and clinical operations teams understand how C1785 is used across payers, what typical service settings look like, and which aspects drive cost and billing complexity. Data not available in the input will be noted explicitly in relevant sections.
Billing Code Overview
HCPCS Level II code C1785 describes an implantable dual-chamber, rate-responsive pacemaker. This device provides electrical stimulation to two cardiac chambers (typically the right atrium and right ventricle) and adjusts pacing rate based on the patient’s physiologic needs.
Service type: Implantation of an implantable cardiac pacemaker (dual-chamber, rate-responsive).
Typical site of service: Hospital inpatient or outpatient surgical setting, or ambulatory surgery center, where device implantation and perioperative monitoring are performed.
Clinical & Coding Specifications
Clinical Context
A 78-year-old patient with symptomatic bradycardia and documented intermittent complete heart block is scheduled for implantation of a C1785 pacemaker (dual chamber, rate-responsive, implantable). The patient presents to an outpatient electrophysiology or inpatient cardiothoracic service after pre-procedure evaluation including history, medication review (anticoagulation management as indicated), pre-op labs, and device counseling. In the procedural suite or operating room, the electrophysiologist implants transvenous right atrial and right ventricular leads connected to a rate-responsive dual-chamber generator, programs initial pacing parameters, and confirms appropriate sensing and pacing thresholds. Post-implant, the patient undergoes device interrogation, chest radiograph to confirm lead position and rule out pneumothorax, and short-term monitoring before discharge with device follow-up scheduled at 1–2 weeks and routine follow-up at 3 months.
