CPT code 58611 – Tubal ligation at cesarean section

Key Takeaways

CPT 58611 is an add-on code (+58611) for tubal ligation at cesarean section or intra-abdominal surgery, always reported alongside a primary C-section code such as 59510 or 59514.

Federal regulations require signed sterilization consent at least 30 days before the procedure for Medicare and Medicaid coverage, with no exceptions.

Modifier -80 is used when an assistant surgeon independently bills 58611. The code is exempt from modifier -51 (multiple procedures) as an add-on.

Pabau’s claims management software helps OB-GYN practices track consent timing, attach required documentation, and submit clean claims for add-on codes like 58611.

CPT Code 58611: definition, section, and add-on status

CPT Code 58611 describes ligation or transection of oviduct(s) when performed at the time of cesarean delivery or intra-abdominal surgery. The American Medical Association (AMA), which maintains the CPT code set, classifies 58611 under the section “Incision Procedures on the Oviduct/Fallopian Tube.”

The plus sign (+) prefix marks 58611 as an add-on code. That means it can never stand alone on a claim. It must always be billed in conjunction with the primary procedure code representing the cesarean delivery or intra-abdominal surgery during which the tubal ligation was performed.

When to use CPT 58611: indications and clinical scenarios

Use CPT Code 58611 when the surgeon performs tubal ligation or oviduct transection during the same operative session as a cesarean section or other open intra-abdominal surgery. The code is not appropriate for a standalone sterilization procedure, and it is not reported when the fallopian tube procedure is performed laparoscopically rather than through an open abdominal approach.

Three clinical scenarios warrant reporting 58611. First, planned postpartum sterilization at the time of a scheduled cesarean delivery. Second, sterilization performed at an unplanned cesarean when the patient has a valid consent form on file meeting the 30-day requirement. Third, tubal ligation performed incidentally during other open intra-abdominal surgery such as an ovarian cystectomy or myomectomy, where the primary code reflects the principal procedure rather than a cesarean delivery code.

• Billable scenario: Patient undergoes scheduled cesarean delivery (59510) with simultaneous bilateral tubal ligation. Report 59510 + 58611.
• Billable scenario: Cesarean delivery (59514) with oviduct transection at same sitting. Report 59514 + 58611.
• Not billable as 58611: Laparoscopic tubal ligation performed as a standalone procedure after delivery. Report 58661 instead.
• Not billable as 58611: Salpingectomy (removal of fallopian tube). Report 58700 or 58661 depending on approach and extent.

Billing guidelines for CPT Code 58611

Because 58611 is an add-on code, it requires a primary CPT code on the same claim. Submitting it without the appropriate primary code is the most common reason for outright denial. Understanding what medical billing involves for add-on codes is essential before building your claim.

The primary codes most often paired with 58611 are the cesarean delivery family. Payers expect the code to appear as a secondary line item, not the lead procedure. Claims management software that enforces add-on code pairing logic at submission can catch missing primaries before the claim reaches the payer. For OB-GYN practice management software with built-in coding validation, this check happens automatically.

Always confirm that submitting a clean claim includes a matching primary code before sending. Payers audit add-on code pairs and will reject a lone 58611 on sight.

CPT 58611 modifier guidelines

CPT Code 58611 as an add-on code is automatically exempt from modifier -51 (multiple procedures), so you never append -51 to this code. The two modifiers that do apply in specific circumstances are -80 and -62.

CPT 58611 vs CPT 58661: related fallopian tube codes and key differences

The most common coding confusion for this procedure family is between 58611 and 58661. Getting these wrong leads to either under-reimbursement (billing an add-on when a standalone was performed) or denial (billing a standalone when only an add-on was warranted). For a broader overview of the IVF and reproductive procedure CPT code family, see our related guide.

Other related codes in this family include 58670 (laparoscopic sterilization with electrocoagulation), 58671 (laparoscopic sterilization with occlusion by device), and 58700 (salpingectomy for non-laparoscopic fallopian tube removal).

Medicare coverage and payer policies for CPT Code 58611

Medicare covers CPT Code 58611 under the National Coverage Determination (NCD) for sterilization, provided the procedure meets coverage conditions. Noridian Medicare (JE Part B) publishes the applicable sterilization policy, which confirms coverage when the procedure is performed at the time of cesarean delivery and is medically necessary.

The single most consequential rule for Medicare and Medicaid coverage of 58611 is the sterilization consent timing requirement. Under 42 CFR Part 441, Subpart F, the patient must sign the sterilization consent form at least 30 days before the scheduled procedure date. Procedures performed within the 30-day window are not covered, regardless of medical necessity documentation. Before submitting a 58611 claim, confirm the consent date in the chart. A single-day error causes a non-covered denial that cannot be corrected after the fact.

Confirm insurance eligibility verification and sterilization benefit coverage before the procedure, and review your practice’s medical billing compliance requirements for sterilization procedures in your state.

• Medicare: Covered under NCD for sterilization; 30-day consent requirement is federal law and applies uniformly.
• Medicaid: Coverage follows federal minimums but state-specific rules may impose additional documentation or consent requirements. Confirm your state’s Medicaid policy before assuming coverage.
• Commercial payers: Most major commercial plans cover tubal ligation at cesarean section. Prior authorization requirements vary by carrier and plan. Verify before scheduling.
• Non-covered scenarios: Consent not obtained 30+ days prior; sterilization performed for reasons that do not meet the payer’s medical necessity criteria; missing operative documentation.

CPT 58611 reimbursement and fee schedule data

Because CPT Code 58611 is an add-on code, its relative value units (RVUs) are lower than a comparable standalone procedure. The work RVU reflects only the additional physician effort for the tubal ligation over and above the primary cesarean delivery already being compensated. For current payment amounts by geographic area, use the CMS Physician Fee Schedule lookup tool and the FastRVU 2026 RVU lookup.

Medicare reimburses 58611 at approximately $150 to $200 nationally for 2025/2026, though geographic practice cost index (GPCI) adjustments mean the actual payment varies by location. Commercial payer rates typically range from 110% to 150% of the Medicare fee schedule, depending on your contracted rate. Verify your actual contracted amount through your payer remittance data.

Submitting claims electronically via Claim.MD, Pabau’s US clearinghouse partner, sends 58611 through real-time eligibility checks before the claim reaches the payer, reducing the risk of preventable denials on the add-on code pairing. After payment, the system returns electronic remittance advice (ERA) files so your billing team can reconcile the 58611 payment against the primary code payment on the same claim.

Understanding how 58611 fits into your practice’s broader revenue cycle management process helps identify whether add-on code denials are a systematic issue or isolated incidents.

Documentation requirements for CPT Code 58611

Documentation for CPT Code 58611 must establish three things: that the tubal ligation was performed during the operative session, that sterilization consent was signed at the required time, and that the ICD-10 diagnosis code supports medical necessity. Missing any of these elements creates a denial that typically cannot be corrected on appeal.

• Operative note: Must describe the tubal ligation or transection as a distinct procedural step within the cesarean delivery operative report, including the technique used (ligation, cautery, transection) and whether the procedure was bilateral.
• Sterilization consent form: The signed, dated federal consent form must be in the record. The signature date must be at least 30 days before the procedure date. The consent must be in the patient’s primary language or include interpreter certification.
• Medical necessity documentation: For most payers this is met by the encounter diagnosis. For Medicare, document that the sterilization was requested by the patient and is not being performed under coercion.
• Primary procedure documentation: The cesarean delivery must be fully documented, as 58611 cannot exist on a claim without its primary code.

A well-structured superbill documentation workflow that captures consent dates alongside procedure codes prevents the consent-timing denial before it occurs. The digital forms built into Pabau can track sterilization consent form completion and date-stamp the signature electronically, giving the billing team a verifiable record at claim time.

ICD-10 diagnosis codes to report with CPT 58611

Every CPT Code 58611 claim requires at least one ICD-10-CM diagnosis code that establishes why the sterilization was performed. The appropriate code depends on the clinical context: was this a planned elective sterilization, or was it performed in the context of an obstetric condition?

ICD-10-CM codes update annually each October 1. Verify that Z30.2 and any companion codes you use remain active in the current fiscal year’s code set before billing.

Common billing errors and denial reasons for CPT Code 58611

CPT Code 58611 has a predictable denial pattern. Understanding the top reasons claims fail helps a billing team resolve them before submission rather than on appeal. Sound denial management strategies for sterilization codes start with catching these errors upstream.

• No primary code on the claim: 58611 submitted without a paired cesarean delivery code. The payer rejects it as an unbundled add-on. Always include the primary code on the same claim.
• Consent timing violation: Sterilization consent was signed fewer than 30 days before the procedure. Medicare and Medicaid will not pay, and this denial is not appealable on clinical grounds. The documentation error is the denial.
• Incorrect modifier appended: Modifier -51 applied to 58611. As an add-on code, 58611 is exempt from -51. Applying it may trigger a payment reduction or rejection.
• Missing operative note detail: The tubal ligation is referenced but not described as a discrete procedural step in the operative report. Payers audit operative notes on sterilization claims.
• Wrong code for approach: The procedure was laparoscopic but 58611 was billed instead of 58661. The approach documented in the operative note must match the CPT code billed.
• ICD-10 code mismatch: The diagnosis code does not support sterilization as the indication. Ensure Z30.2 or an appropriate obstetric code is on the claim alongside the procedure codes.

Conclusion

CPT Code 58611 is straightforward when the rules are followed consistently: pair it with the right primary code, verify consent was signed 30 days prior, document the procedure as a distinct operative step, and use Z30.2 for the diagnosis. The denials that appear on 58611 claims are almost entirely preventable with the right pre-submission workflow.
