CPT code 58600 – Tubal ligation or transection

Key takeaways

CPT code 58600 describes open tubal ligation or transection through an abdominal or vaginal approach, not laparoscopic sterilization.

The descriptor already covers unilateral or bilateral procedures, so modifier 50 does not apply and appending it causes an overpayment.

Medicaid denies sterilization claims that lack a Consent for Sterilization form (HHS-687) signed 30 to 180 days before the procedure.

Laparoscopic sterilization is billed with 58670 or 58671, and sterilization at cesarean delivery uses add-on code 58611.

Pabau, the practice platform we build, submits and tracks 58600 claims electronically through Claim.MD.

CPT code 58600: definition and clinical description

CPT code 58600 is the American Medical Association’s code for ligation or transection of the fallopian tube(s), via abdominal or vaginal approach, unilateral or bilateral. In the AMA’s CPT code set, both open approaches and either laterality fall under this one code. You bill a single unit whether the surgeon ligated one tube or both.

The code sits in the Oviduct/Ovary incision range, 58600-58615, while laparoscopic procedures on the tubes sit at 58660-58679. The approach and the timing of the procedure decide whether 58600, 58605, 58611, 58670 or 58671 is correct.

Abdominal vs vaginal approach: same code, different documentation

Both approaches fall under CPT code 58600, but the operative report must clearly state which was used. Payers and auditors look for this language during claim review, and an ambiguous report can trigger a documentation request that delays payment.

Neither approach requires a different code. What changes is the documentation language the auditor will scan for. Coders reviewing an operative report should confirm three points:

• The approach is stated explicitly.
• The ligation or transection method is described (suture, thermal or mechanical occlusion).
• Laterality is addressed, even when both tubes were ligated.

A report that covers all three rarely draws a documentation request.

Unilateral vs bilateral: why modifier 50 does not apply

Modifier 50 (bilateral procedure) is not appended to CPT code 58600. The official AMA descriptor already states “unilateral or bilateral,” so one billing unit covers either scenario. Modifier 50 tells payers to pay 150% of the single-procedure rate. On this code, that creates an overpayment that invites audits and takebacks.

• Do not append: Modifier 50, or modifier LT/RT to indicate tube-specific laterality.
• Append when the payer requires it: Modifier 52 (reduced services) if only part of the planned procedure was completed.
• Append with support: Modifier 22 (unusual procedural services), only when the procedure was significantly more complex than typical and the documentation shows it.
• Exception to watch: Some commercial payers deviate from CMS guidance and require bilateral reporting, so check each payer’s policy before submission.

The rule is straightforward: if the descriptor already contains “unilateral or bilateral,” modifier 50 does not apply. Coders who inherit claims from another biller should verify modifier history before re-submission to avoid a duplicate overpayment flag.

CPT 58600 vs 58611, 58670 and 58671: choosing the right code

These codes cover the same anatomical region but describe different procedures. Picking the wrong one leads to approach-mismatch denials and can trigger an upcoding review.

58600 vs 58670 and 58671: If the operative report mentions trocars, ports, insufflation or a laparoscope, the sterilization was laparoscopic. Report 58670 for fulguration, or 58671 for occlusion by a band, clip or Falope ring. CPT code 58600 is reserved for open abdominal and vaginal approaches.

58600 vs 58611: Tubal ligation can happen at the same operative session as a cesarean delivery (CPT 59510 or similar). In that case, report 58611 as the add-on code, not 58600. Billing 58600 alongside a cesarean code will often bundle incorrectly or generate an edit requiring documentation to unbundle.

The decision path below runs the same checks in the order a coder reads the operative report.

Related tubal sterilization codes from 58600 to 58671

Before finalizing code selection, confirm where the procedure falls in the full code range. The table below covers the codes coders meet most often alongside CPT code 58600 in sterilization billing.

Salpingectomy removes the tube rather than ligating it, so it is never billed as 58600. A laparoscopic removal is 58661, and an open salpingectomy is 58700.

ICD-10 diagnosis codes to pair with tubal ligation

Diagnosis code selection for CPT code 58600 depends on whether the sterilization is elective or medically necessary. Pairing the wrong ICD-10 code with 58600 is a common denial trigger, particularly for Medicaid and Medicare claims where coverage is conditioned on clinical indication.

Z30.2 is the default pairing for elective sterilization. Medicare, however, does not cover voluntary sterilization under NCD 230.3 (discussed below), so submitting Z30.2 to Medicare results in a non-covered denial by design. For more on ICD-10-CM code structure, the CMS ICD-10 codes page publishes annual updates and valid code lists.

Medicaid sterilization consent and prior authorization

Federal Medicaid regulations under 42 CFR Part 441 Subpart F require a voluntary consent form before any sterilization procedure is reimbursed. A missing or late form is one of the most common reasons a Medicaid claim for CPT code 58600 is denied.

• Consent for Sterilization form (HHS-687): The patient must sign it at least 30 days, and no more than 180 days, before the procedure.
• Emergency exception: For premature delivery or emergency abdominal surgery, consent must be signed at least 72 hours before the procedure. For a premature delivery, it must also be signed at least 30 days before the expected delivery date.
• Age minimum: The patient must be at least 21 years old at the time of consent under federal Medicaid rules. Some states apply stricter age requirements.
• Voluntary attestation: The surgeon must attest on the form that the patient was informed of the permanent nature of the procedure and gave voluntary consent.
• Form retention: Keep the signed HHS-687 in the patient record. Submit it with the claim when the state Medicaid program or plan requires it.

Prior authorization is a separate requirement. It varies by state Medicaid program, managed care plan and commercial payer, so verify it through each payer’s provider portal before scheduling. Practices with high Medicaid sterilization volumes should confirm the consent date on a pre-procedure checklist, since a late signature cannot be corrected after surgery.

Medicare coverage and 2026 reimbursement

Medicare does not cover voluntary sterilization under National Coverage Determination (NCD) 230.3. Submitting a CPT code 58600 claim to Medicare for elective sterilization will result in a non-covered denial. Coverage exists only when the sterilization is medically necessary, such as when performed to address tubal pathology rather than for contraceptive intent.

When Medicare does cover a 58600 procedure as medically necessary, reimbursement follows the Medicare Physician Fee Schedule (MPFS). The 2026 figures below are national unadjusted values at the $33.4009 conversion factor. Actual payment varies by locality through the Geographic Practice Cost Index (GPCI) adjustment. Verify current rates using the CMS Physician Fee Schedule lookup tool or a dedicated RVU calculator such as FastRVU’s 2026 lookup.

Important: Facility and non-facility payment are the same for 58600, because its practice expense RVUs are 3.17 in both settings. Locality adjustment moves the final figure, and CMS updates the values each January. Confirm the figure for your locality in the CMS file before quoting it.

Documentation requirements: what the operative report must include

An operative report that supports CPT code 58600 must contain specific elements. Auditors reviewing 58600 claims check for each of them. Missing any one can turn a paid claim into a documentation request or a denial on re-audit.

• Approach statement: “Abdominal approach via mini-laparotomy incision” or “vaginal approach via colpotomy,” stated explicitly rather than implied.
• Tube identification: The report confirms the fallopian tube(s) were visualized and identified before ligation.
• Ligation or transection method: Suture ligation, electrocautery, Filshie clip, Hulka clip, Pomeroy technique or another named method.
• Laterality statement: “Right fallopian tube,” “left fallopian tube” or “bilateral fallopian tubes,” even though 58600 covers both.
• Sterilization intent: A note confirming the procedure was performed for sterilization or for documented medical necessity.
• Surgeon attestation: A signed operative note confirming the physician performed or directly supervised the procedure.
• Complications or unusual circumstances: Any deviation from standard technique, noted to support modifier 22 where it applies.

Ensuring clean claim submission starts at documentation, before coding begins. Operative note templates that carry these elements as standard fields cut rework, because the coder no longer has to query the surgeon. Pabau’s digital forms and clinical note templates let OB/GYN teams capture them at the point of care.

Top denial reasons for 58600 claims and how to prevent them

Most CPT code 58600 denials follow a short list of predictable patterns, and the claim denial codes on the remittance show which one hit. Each pattern has a prevention step you can build into the billing workflow.

Proactive denial management workflows catch most of these patterns before a claim leaves the practice. The result is fewer first-pass denials and less rework for the billing team.

How claims management software supports 58600 billing

Without a connected system, billing teams check consent dates, approach language and modifiers by hand. The consent form often sits in a paper chart while the claim lives in a separate billing tool.

Pabau’s OB/GYN claims software keeps the signed consent form, the operative note and the claim in one patient record. Your team submits and tracks each claim electronically through Claim.MD, so the claim status sits next to the documents a payer may request.

When a Medicaid plan asks for the HHS-687 or an auditor asks for the operative report, the answer is one search away.

Keep consent forms and claims in one record

Pabau stores signed sterilization consent forms with the patient record, then submits and tracks claims electronically through Claim.MD. Your team finds the form and the claim status in one place.

Conclusion

Treat 58600 as the fallback code. Rule out a laparoscopic approach, a cesarean session, a postpartum stay and device occlusion first. Bill 58600 only when the open report clears all four.

A wrong code or a stray modifier 50 can be corrected and resubmitted. A late Consent for Sterilization form (HHS-687) cannot, because the 30-day wait cannot be met after surgery. Put your checking effort into the consent date at scheduling, not into the claim afterward.

Pabau keeps the signed form and the claim in the same patient record, so the consent date is easy to confirm before surgery. Book a demo to see how it fits your OB/GYN billing workflow.
