Billing tips

Verify setting-specific reimbursement before scheduling. Non-facility ($339.31) pays 137% more than facility ($142.97).
Impact: Performing in office-based setting versus hospital outpatient generates $196.34 additional revenue per procedure for the practice.
Document implant depth precisely. If dissection extends beyond superficial layers into deep fascia or muscle, consider 20680 instead.
Impact: CPT 20680 (deep removal) has Work RVU of 3.37 versus 1.79 for 20670, representing potential 88% increase in physician work component if clinically appropriate.
When removing multiple superficial implants, bill 20670 for the first and add modifier 59 to subsequent line items only if at distinct anatomic sites.
Impact: Proper modifier 59 usage can capture payment for multiple removals; incorrect use may trigger bundling edits reducing reimbursement by 100% on secondary procedures.
Link to appropriate ICD-10 codes documenting mechanical complication (T84.x), encounter for implant removal (Z45.x), or site-specific aftercare (Z47.x).
Impact: Improper diagnosis coding is responsible for 30-40% of 20670 denials; correct linkage establishes medical necessity and reduces appeal requirements.
Check global period of original implant placement. If within 90-day global, append modifier 78 or 79 and document why removal is medically necessary versus planned.
Impact: Failure to use global modifiers results in automatic denial. Modifier 78 reduces payment to approximately $100-140, while 79 preserves full $339.31 if properly justified.
For Medicare patients, verify LCD/NCD policies requiring prior authorization for implant removal in your jurisdiction before scheduling.

Frequently asked questions

What is the Medicare reimbursement rate for CPT code 20670 in 2025?

Medicare pays $339.31 for CPT 20670 in non-facility settings and $142.97 in facility settings based on the 2025 national average rates. Actual payment may vary by geographic location based on the GPCI adjustments in your MAC jurisdiction.

What is the difference between CPT 20670 and 20680?

CPT 20670 is for removal of superficial implants located in subcutaneous tissue or superficial to deep fascia, while 20680 is for deep implants requiring dissection through deep fascia into muscle or deeper structures. The depth of dissection documented in the operative report determines correct code selection, with 20680 having significantly higher RVUs (5.72 total vs 10.49 for 20670).

Can I bill an E/M visit on the same day as CPT 20670?

Yes, but only if the E/M service represents a separately identifiable evaluation beyond the routine pre-procedure assessment. Append modifier 25 to the E/M code and ensure documentation clearly shows distinct history, exam, and medical decision-making separate from the decision for surgery and procedure itself. Most same-day E/M services for routine pre-procedure checks are bundled and not separately billable.

How many RVUs is CPT code 20670 worth in 2025?

CPT 20670 has a total of 10.49 RVUs: 1.79 work RVUs, 8.42 practice expense RVUs (non-facility), 2.35 practice expense RVUs (facility), and 0.28 malpractice RVUs. The conversion factor for 2025 is 32.3465.

What diagnosis codes support medical necessity for CPT 20670?

Common supporting ICD-10 codes include T84.0- (mechanical complication of internal orthopedic devices), T84.6- (infection of internal orthopedic prosthetic devices), Z45.42 (encounter for adjustment and management of bone growth stimulator), Z47.2 (encounter for removal of internal fixation device), and M79.6- (pain in limb). The diagnosis must clearly justify why removal is medically necessary rather than purely elective.

Can CPT 20670 be billed bilaterally with modifier 50?

No, CPT 20670 is not designated as a bilateral procedure eligible for modifier 50. When removing superficial implants from both sides, bill two separate line items with modifiers RT (right) and LT (left), or use modifier 59 if removing multiple implants from distinct anatomic sites to indicate separate procedures.

Does CPT 20670 have a global period?

Yes, CPT 20670 has a 10-day global period. This includes the day of surgery plus 10 postoperative days during which related E/M services are bundled. Complications or unrelated services during this period require appropriate modifiers (24 for unrelated E/M, 78 for related return to OR, 79 for unrelated procedure).
