Identify the primary procedure code and confirm it is documented as performed on the same date by the same surgeon
Specify the anatomic location of device placement (e.g., subfascial plane, exact surgical site)
Document the type and name of the drug-delivery device inserted, including lot number if applicable
Describe the creation of the pocket or incision used for deep device placement, separate from the primary procedure steps
Record clinical rationale for placing a deep drug-delivery device at time of primary surgery

What this code covers

Source · Editorial summary grounded in 5 cited references ↓

CPT 20700 covers the manual preparation of a drug-delivery device and its insertion into deep tissue — specifically subfascial planes — performed alongside a separate primary musculoskeletal procedure. Because this is a ZZZ global add-on code, it is never billed alone. It must be reported alongside an acceptable primary procedure code performed by the same surgeon on the same date of service.

The code describes the work of creating an incision, forming a subfascial pocket, preparing the device, and placing it — distinct from the primary surgical work. Common clinical contexts include implantable antibiotic or analgesic delivery systems placed at the time of orthopedic or podiatric surgery. The related code 20701 covers removal of the same class of device; 20702 addresses a manual preparation and insertion scenario with a distinct device configuration.

As a Type 3 NCCI add-on code, 20700 has some specifically identified primary codes but contractors may recognize other acceptable primary procedures beyond that list. Verify payer-specific primary code acceptability before submitting — some commercial payers restrict the pairing more narrowly than Medicare.

Work RVU vs. total RVU

The work RVU (1.46) is the surgeon's own effort — the figure physician pay and productivity targets are built on. The total RVU (2.54) adds practice overhead and malpractice, and is what drives the Medicare payment below.

Work RVU	1.46
Practice expense RVU	0.82
Malpractice RVU	0.26
Total RVU	2.54

Payment by site of service

Medicare pays different rates by setting. HOPD typically pays substantially more than ASC for the same procedure.

Common denial reasons

The recurring reasons claims for CPT 20700 get rejected.

Source · Editorial brief grounded in CMS NCCI edits, AAOS coding appeals, and cited references ↓

Billed without an acceptable primary procedure code on the same claim — add-on codes require a paired primary
Primary procedure code not recognized by the payer's contractor as an acceptable companion for 20700
Missing operative note documentation of the subfascial pocket creation or device preparation distinct from primary procedure work
Incorrect linkage of diagnosis codes that do not support the need for an implantable drug-delivery device at time of surgery

Frequently asked questions

Source · Generated from the editorial pipeline, verified against 5 cited references ↓

01Can 20700 be billed as a standalone code?

No. It carries a ZZZ global period and is an NCCI add-on code. Payment requires an acceptable primary procedure code from the same surgeon on the same date.

02Which primary procedures pair with 20700?

20700 is a Type 3 NCCI add-on, meaning some primaries are specifically listed but the list is not exclusive. Medicare contractors can recognize additional primary codes. Check your MAC's guidance and the CMS NCCI add-on code file annually — it updates each January 1.

03Does 20700 reset or have its own global period?

No. ZZZ global means no independent global period applies. The global clock belongs entirely to the primary procedure reported alongside it.

04How does 20700 differ from 20702?

Both describe manual preparation and deep insertion of a drug-delivery device, but they differ in device configuration. Review the operative scenario carefully against each code's descriptor before selecting. 20701 covers removal of the same class of device.

05Should modifier 59 be appended to 20700?

Only if a payer edit bundles 20700 with the primary and the clinical circumstances support a distinct procedural service. Modifier 59 does not substitute for a proper primary code pairing — it resolves a specific NCCI PTP edit when documentation supports separate service.

06Is 20700 payable in an ASC or HOPD setting?

CMS does not publish a separate ASC or HOPD facility payment for 20700 — its reimbursement flows through the primary procedure's facility payment. Confirm facility billing rules with your MAC.

Mira Scribe

Mira's AI scribe captures the device name, anatomic placement site (subfascial layer and surgical location), pocket creation technique, and the primary procedure performed on the same date — the four elements auditors check first on 20700 claims. Without explicit documentation linking device prep and placement to a distinct step beyond the primary procedure, payers collapse the service into the primary code and deny 20700.
