Billing tips

Document the specific medical necessity for removing the expander without proceeding to implant placement, such as infection, exposure, patient decision, or planned staged approach
Impact: Prevents medical necessity denials which account for approximately 35% of rejections for this code; can preserve the full $545.36 reimbursement
Do not bill 11971 on the same date as implant insertion codes (11970); these are mutually exclusive procedures
Impact: Prevents bundling denials and potential audit flags; codes billed together result in automatic denial of one or both procedures
For bilateral removals, use modifier 50 instead of billing the code twice with RT/LT modifiers, as most payers follow CMS bilateral surgery rules
Impact: Ensures proper payment at 150% rate ($818.04) rather than risk of second side denial or 100% payment only
Link to appropriate ICD-10 codes indicating complication (T85.42XA for infection, T85.79XA for other complications) or reason for removal (Z45.81 for encounter for adjustment/removal)
Impact: Strengthens medical necessity documentation and reduces denial rate by approximately 25-30%
Verify the facility versus non-facility setting match, as both rates are identical at $545.36 for 2025, but incorrect place of service coding can trigger payment delays
Impact: Ensures timely payment processing and avoids resubmission delays of 30-45 days
When performed during global period of previous breast surgery, append modifier 78 or 79 as appropriate and document the distinct nature or complication requiring return to OR
Modifier 78 reduces payment to approximately $381.75 but ensures payment rather than complete denial for global period procedures

Frequently asked questions

What is the Medicare reimbursement rate for CPT code 11971 in 2025?

The 2025 Medicare national average reimbursement for CPT 11971 is $545.36 for both facility and non-facility settings. This is based on 16.86 total RVUs (7.02 work RVU, 8.55 PE RVU, 1.29 MP RVU) multiplied by the 2025 conversion factor of 32.3465.

What is the difference between CPT 11971 and 11970?

CPT 11971 is for removal of a tissue expander WITHOUT inserting a permanent implant, while CPT 11970 is for replacement of a tissue expander WITH insertion of a permanent breast implant during the same procedure. These codes are mutually exclusive and cannot be billed together on the same date of service.

Can CPT 11971 be billed bilaterally with modifier 50?

Yes, CPT 11971 can be billed with modifier 50 when tissue expanders are removed from both breasts during the same operative session without implant insertion. Medicare typically reimburses bilateral procedures at 150% of the unilateral rate, resulting in approximately $818.04 for bilateral removal.

What diagnosis codes support medical necessity for CPT 11971?

Common supporting ICD-10 codes include T85.42XA (infection of breast prosthesis and implant), T85.79XA (other complications), T85.43XA (capsular contracture), Z45.81 (encounter for adjustment and management of implanted device), and Z90.1- (acquired absence of breast). The diagnosis must explain why the expander is being removed without proceeding to implant placement.

How many RVUs is CPT code 11971 worth in 2025?

CPT 11971 has 16.86 total RVUs in 2025, consisting of 7.02 work RVUs, 8.55 practice expense RVUs (both facility and non-facility), and 1.29 malpractice RVUs. This is a moderate-value surgical code reflecting the complexity of tissue expander removal.

Can CPT 11971 be billed during the global period of the original expander insertion?

Yes, but it requires modifier 78 if the removal is due to a complication requiring return to the operating room during the postoperative period, or modifier 79 if it's an unrelated procedure. Modifier 78 typically reduces reimbursement to approximately 70% of the usual fee. Documentation must clearly establish the medical necessity for early removal.

What specialties typically bill CPT code 11971?

CPT 11971 is most commonly billed by plastic surgeons and breast surgeons who perform reconstructive procedures. General surgeons with reconstructive experience and surgical oncologists may also bill this code when managing complications of tissue expanders placed during breast reconstruction or other tissue expansion procedures.
