Summary & Overview
CPT 20700: Device Preparation and Subfascial Pocket Creation
CPT code 20700 captures the manual preparation of a drug delivery device and the creation of a subfascial pocket to accommodate deep insertion, billed in addition to a separate primary procedure. This ancillary surgical service is clinically significant because it documents work distinct from the primary operation and supports correct procedure coding and payment for device implantation steps. Nationally, accurate reporting of this code affects facility and professional claims that include implantable drug delivery systems and similar devices.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of where CPT code 20700 applies clinically, common billing contexts, and the implications for claim documentation and coding sequencing. The publication outlines expected sites of service, examples of clinical scenarios where the code is reported alongside a primary procedure, and a summary of payer considerations and coding usage patterns where available.
This resource is intended to help coding professionals, billing managers, and clinical teams understand the clinical role of CPT code 20700, how it is distinguished from primary procedure codes, and what readers should review in clinical documentation and claim composition.

Billing Code Overview
CPT code 20700 describes manual preparation of a drug delivery device for deep insertion into subfascial tissues and the creation of the necessary incisions and pocket for insertion of the device as part of a separate primary procedure. This code is reported in addition to the code for the primary procedure.
-
Service type: Surgical device preparation and pocket creation as an adjunct to a separate primary operative procedure
-
Typical site of service: Operating room or procedure suite during the primary surgical encounter
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with chronic, refractory neuropathic pain of the lower back and bilateral legs is scheduled for implantation of a spinal cord stimulator generator as the primary procedure. The operating provider manually prepares the device pocket through creation of skin and subcutaneous/subfascial incisions and performs deep tissue dissection to accommodate the pulse generator. The procedure to create the pocket and prepare the drug delivery device for deep subfascial insertion is performed in the operating room of an ambulatory surgery center or hospital inpatient surgical suite. Preoperative workflow includes device selection, sterile preparation, informed consent, and anesthesia assessment (general or monitored anesthesia care). Intraoperative workflow includes incision planning, creation of the pocket in subfascial tissues, hemostasis, device placement, and closure; this work is reported in addition to the primary implantation code using 20700. Postoperative workflow includes device programming, wound care instructions, and routine postoperative follow-up visits in clinic or by device representative. Typical payors include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
11 | Normal/standard service | When 20700 is performed as the primary service without unusual circumstances |
22 | Increased procedural services | When significantly greater effort than usual is required to create the deep subfascial pocket |
23 | Unusual anesthesia | When 20700 is performed with anesthesia that is medically necessary due to unusual circumstances |
50 | Bilateral procedure | When identical deep pocket creation is performed on both right and left sides for bilateral device placement |
52 | Reduced services | When the pocket creation for 20700 is partially reduced or not completed |
53 | Discontinued procedure | When the pocket creation is started but discontinued for patient safety reasons |
59 | Distinct procedural service | When 20700 represents a distinct, separate service from the primary procedure and documentation supports separate reporting |
62 | Two surgeons | When two surgeons of different specialties work together performing distinct parts (co-surgery) on pocket creation |
63 | Procedure performed on infants less than 4 kg | When applicable for neonatal device implantations requiring special coding |
78 | Unplanned return to the operating/procedure room by the same physician following initial procedure for a related procedure during the postoperative period | When a return trip to the OR is required to revise or re-create the pocket |
79 | Unrelated procedure or service by the same physician during the postoperative period | When an unrelated surgical procedure occurs during the global period |
AS | Ambulatory surgery center facility service | To indicate services provided in an ASC when facility reporting applies |
LT | Left side | To identify laterality when pocket creation is performed on the left |
