Summary & Overview
CPT 0870T: Minimally Invasive Peritoneal Ascites Pump Implantation
CPT code 0870T represents the minimally invasive implantation of a peritoneal ascites pump system that shuttles ascitic fluid from the peritoneal cavity to the bladder via an implanted pump and tubing. The code captures a device-based surgical service that may include intraoperative imaging and postoperative pump programming. Nationally, this code is relevant as an emerging option for management of refractory ascites and carries implications for device coverage, facility utilization, and specialty procedural billing.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise description of the clinical service, expected sites of care, and the common billing context for the code. The publication provides benchmarks where available, summarizes payer coverage trends, and outlines the clinical workflow tied to the code — including perioperative imaging and device programming components. The content is intended to inform coding and reimbursement stakeholders, clinical leaders, and health policy analysts about how this device implantation procedure is classified and billed under CPT.
Data not available in the input is noted where relevant, including specific payer policies, associated taxonomies, and ICD-10 diagnosis pairings.
Billing Code Overview
CPT code 0870T describes a minimally invasive implantation of a peritoneal ascites pump system. The procedure involves placing a subcutaneous pump reservoir in a pocket beneath the skin and tunneling catheters or tubing to carry ascitic fluid from the abdominal peritoneal space to the bladder. The service may include the use of imaging guidance during device placement and programming the pump after implantation.
Service type: Implantation of peritoneal ascites pump system (minimally invasive)
Typical site of service: Hospital outpatient department or ambulatory surgery center, where minimally invasive device implantation and intraoperative imaging are routinely performed.
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with recurrent, medically refractory malignant ascites due to metastatic ovarian carcinoma presents for peritoneal ascites pump system implantation. The patient experiences daily symptomatic abdominal distension, dyspnea, and impaired quality of life despite repeated paracenteses. After multidisciplinary evaluation by medical oncology and palliative care, the interventional radiology or surgical team schedules a minimally invasive implantation. Under conscious sedation or general anesthesia in an outpatient ambulatory surgery center or hospital operating room, the provider creates a subcutaneous pocket for the pump, tunnels and inserts catheters from the peritoneal cavity to the bladder, uses fluoroscopic or ultrasound imaging to confirm catheter positions, secures the pump and leads, closes incisions, and programs the pump prior to recovery. Typical peri-procedural workflow includes pre-procedure imaging review, informed consent, antimicrobial prophylaxis, sterile technique, intraoperative imaging guidance, device interrogation/programmation, post-anesthesia recovery, a brief observation period for output and hemodynamic stability, and discharge with wound and device care instructions and scheduled follow-up for device checks and ascites management.

| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the work or complexity substantially exceeds typical for the implant procedure due to extensive adhesiolysis or altered anatomy. |
