Summary & Overview
CPT 20705: Manual Removal of Intra–Articular Drug Delivery Device
CPT code 20705 identifies the manual removal of an intra–articular drug delivery device from a joint performed in conjunction with a separately reported primary procedure. Nationally, this code matters because it clarifies reporting for adjunct intraoperative work tied to joint surgeries and affects how surgical episodes are documented and billed. Accurate use supports granular capture of device-related work and can affect aggregated procedure counts and episode-level reporting.
Key payers commonly considered in national billing guidance include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical context, guidance on typical service settings, and the types of benchmarks and policy topics that influence its use. The publication covers national reimbursement and coding benchmarks, relevant policy updates that affect intraoperative adjunct services, and clinical considerations for documenting device removal within a primary joint procedure. The summary highlights common billing modifiers and notation practices, while noting when input data is not available for specific fields such as associated taxonomies or ICD-10 mappings. Data not available in the input will be identified as such in the appropriate sections.
Billing Code Overview
CPT code 20705 describes the manual removal of an intra–articular drug delivery device from a joint when the removal is performed as part of a separately reported primary procedure. This is an operative/adjunct procedural service tied to a surgical encounter.
-
Service type: Manual removal of an intra–articular implant/device as an adjunct to a primary surgical procedure
-
Typical site of service: Operating room or other intraoperative setting where the primary joint procedure is performed
Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult who previously received an intra‑articular drug delivery implant (for example, a controlled‑release corticosteroid or analgesic depot) placed within a synovial joint during a prior procedure. At a subsequent operative session—commonly during a primary joint procedure such as open or arthroscopic arthroplasty, synovectomy, debridement, or hardware removal—the provider manually removes the intra‑articular drug delivery device as a distinct intraoperative step. The workflow: preoperative evaluation documents the existing implant and indication for its removal; the primary procedure is performed (for example, total knee arthroplasty or arthroscopic debridement); the implant is identified under direct visualization and manually extracted; the removal is documented in the operative note as an additional intra‑articular maneuver; and the provider reports 20705 in addition to the CPT code for the primary procedure. Typical sites of service include hospital inpatient operating room or hospital outpatient surgical suites. Typical patient factors include prior joint injections or implants, chronic joint pain or inflammatory arthropathy, and informed consent that includes removal of existing intra‑articular devices.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the removal significantly increases the work, time, or complexity over typical for the primary procedure and documentation supports the increased work. |
