CPT code 58180 – Supracervical abdominal hysterectomy

Key Takeaways

CPT code 58180 covers open abdominal supracervical (subtotal) hysterectomy, with or without removal of tubes and/or ovaries, with cervical stump retained

The key distinction from CPT 58150: 58180 preserves the cervix; 58150 removes it. Both are open abdominal. The operative note must state which anatomy was retained

CPT 58180 carries a 90-day global surgical period under Medicare, meaning most post-op care is bundled into the base payment

Pabau’s claims management software helps OB/GYN practices track prior authorization status, flag NCCI edit conflicts, and submit clean claims for major surgical codes like 58180

CPT Code 58180: Official description and what it covers

CPT code 58180 describes “Supracervical abdominal hysterectomy (subtotal), with or without removal of tube(s), with or without removal of ovary(ies),” as published by the American Medical Association (AMA), the CPT code set’s copyright holder and editorial authority. The code captures one specific procedure: Open surgical removal of the uterine corpus through an abdominal incision, with the cervix remaining in place.

The parenthetical “with or without removal of tube(s), with or without removal of ovary(ies)” is significant. It means oophorectomy and salpingectomy performed at the same operative session are bundled into 58180 when the tubes and ovaries are the only additional structures removed. Separately payable add-on codes apply only when the NCCI edit tables permit distinct reporting (covered in a later section).

CPT 58180 vs 58150: Supracervical vs total abdominal hysterectomy

The anatomical difference between CPT 58180 and CPT 58150 is a single structure: The cervix. CPT 58150 (total abdominal hysterectomy) removes the uterus and cervix together; CPT code 58180 removes the uterine body and leaves the cervical stump. Both use an open abdominal approach, which is the reason they are so frequently confused on claims.

The operative note is the audit anchor. Payers that deny CPT 58180 claims citing “incorrect procedure code” almost always found that the note did not explicitly state the cervix was retained. If the surgeon simply wrote “hysterectomy performed” without specifying supracervical intent, a payer may default to total hysterectomy (58150) and deny the submitted code.

CPT 58180 vs 58571: Open vs laparoscopic supracervical hysterectomy

CPT code 58571 is the laparoscopic supracervical hysterectomy code, covering procedures performed with a uterine specimen weight greater than 250 grams. CPT code 58180 covers the same anatomical procedure performed via open abdominal (laparotomy) incision. The surgical approach is the sole differentiator; the anatomy removed and retained is identical.

Coders must confirm the approach in the operative note before assigning either code. A note that describes trocar placement and pneumoperitoneum is laparoscopic, regardless of whether it later describes a Pfannenstiel incision for specimen retrieval. If the surgeon converts from laparoscopic to open during the procedure, the open code (58180) applies and the conversion should be documented explicitly.

Common indications and ICD-10-CM diagnosis codes for CPT 58180

Payers evaluate the ICD-10-CM diagnosis code to confirm medical necessity for CPT 58180. The most commonly paired diagnoses are uterine leiomyoma, adenomyosis, and abnormal uterine bleeding (AUB) that has failed conservative management. Using an imprecise ICD-10-CM code, or one that does not support the surgical indication, is a reliable path to a medical-necessity denial. Verify codes against the ICD list reference tool each fiscal year, as NCHS updates ICD-10-CM codes annually in October.

Add-on and concomitant codes: Billing oophorectomy and salpingectomy with CPT 58180

The CPT 58180 descriptor includes “with or without removal of tube(s), with or without removal of ovary(ies),” which means routine salpingectomy or oophorectomy performed as the only additional procedure at the same session is already captured in the base code. Reporting a separate oophorectomy or salpingectomy code on the same claim will trigger an NCCI edit bundling denial in most cases.

However, distinct reporting is appropriate in specific circumstances. Consult the current National Correct Coding Initiative (NCCI) edit tables before submitting any additional codes alongside CPT 58180. The scenarios below reflect general coding logic; always verify against current NCCI tables, as edits are updated quarterly by the Centers for Medicare and Medicaid Services (CMS). For gynecologic procedure coding involving reproductive structures, the NCCI policy manual is the authoritative source for bundling determinations.

• CPT 58661 (laparoscopic oophorectomy): This code describes a laparoscopic approach. It cannot be combined with 58180 (open approach) on the same claim without raising an approach-inconsistency flag. If the ovaries were removed during the same open abdominal session, the open oophorectomy is bundled into 58180.
• CPT 58700 (salpingectomy, open): Generally bundled with 58180 per NCCI edits when performed at the same session via the same abdominal incision. Separately reportable if the salpingectomy is for a distinct indication with supporting documentation and an NCCI edit with a modifier indicator of “1” (modifier allowed to override).
• Modifier 51 (multiple procedures): Apply when a separately payable additional procedure is performed at the same session and payer policy permits. Required documentation: The additional procedure must be distinct in purpose, not incidental to the primary surgery.
• Modifier 22 (increased procedural services): Applies to CPT 58180 itself when the procedure is substantially more complex than typical, for example, due to extensive adhesions or prior uterine surgery. Requires an attached operative report and a cover letter quantifying the additional time and effort.

Medicare reimbursement rates for CPT code 58180

Medicare reimburses CPT code 58180 based on the Resource-Based Relative Value Scale (RBRVS): Work RVUs multiplied by a national conversion factor, adjusted by the Geographic Practice Cost Index (GPCI) for the practice location. Exact dollar amounts change with the annual Medicare Physician Fee Schedule (MPFS) final rule published each November. Use the CMS MPFS search tool to retrieve current payment amounts for your specific MAC jurisdiction, or the FastRVU 2026 RVU lookup for a quick RVU breakdown.

Commercial payer rates for CPT 58180 vary by contract and are not publicly standardized. Most commercial payers benchmark somewhere above Medicare rates, but individual contracts govern the actual allowed amount. The AAPC’s CPT code reference provides a useful national benchmark alongside the CMS data. OB/GYN practices submitting CPT 58180 claims through Pabau can route them electronic claims via Claim.MD, Pabau’s integrated US clearinghouse, which connects to over 4,000 payers and supports real-time eligibility checks before the claim is submitted.

Global surgical period and post-op billing for CPT 58180

CPT 58180 carries a 90-day global surgical period under Medicare, confirmed by the CMS Medicare Physician Fee Schedule global-days indicator. This means the base payment for 58180 includes all routine pre-operative services one day before surgery and all routine post-operative care for 90 calendar days following the procedure. Billing separately for routine post-op follow-up visits within that window will result in denial.

Understanding medical billing fundamentals around global periods prevents the most avoidable post-op denials. These categories of services remain separately billable within the 90-day global window:

• Unrelated E&M services (modifier 24): An evaluation and management visit for a condition entirely unrelated to the surgery (for example, a hypertension follow-up). Append modifier 24 to the E&M code and document the unrelated diagnosis clearly.
• Postoperative complications requiring additional surgery: If a complication requires a return to the operating room, the new procedure is separately reportable with modifier 78.
• Staged procedures (modifier 58): A planned related procedure performed during the global period uses modifier 58, triggering a new global period from the staged surgery date.
• Immunosuppressive drugs or implanted device monitoring: These are outside the surgical global package and may be billed separately when clinically indicated.

The pre-operative period for major surgery codes (global period 090) covers one day immediately preceding the surgery. Any E&M service on that day is bundled into the global period payment for CPT 58180 unless a clearly separate, unrelated diagnosis supports modifier 25.

Documentation requirements for CPT 58180

Documentation failures are the primary cause of CPT 58180 claim denials and audit reversals. The operative report must contain specific language to support the code. Superbill documentation that references only a generic “hysterectomy” code without the operative note backing it gives auditors grounds to downcode or deny. The checklist below covers the elements payers consistently audit on 58180 claims.

• Explicit approach statement: “Open abdominal approach via Pfannenstiel (or midline) incision” or equivalent. Laparoscopic language invalidates the 58180 code selection.
• Cervical retention statement: “The cervix was preserved” or “cervical stump left in situ” must appear verbatim. This is the single most audited documentation element for CPT 58180 vs 58150 disputes.
• Uterine specimen description: Document specimen weight and gross appearance. Weight supports coding accuracy for the 58180 vs 58571 distinction (>250 grams triggers the laparoscopic weight-threshold codes).
• Surgical indication tied to ICD-10: The indication in the operative report must align with the ICD-10-CM code submitted on the claim. “Patient with symptomatic leiomyomata uteri, failed conservative management” supports D25.x.
• Structures removed and retained: Explicitly list all structures removed (uterine corpus, right/left fallopian tube if applicable, right/left ovary if applicable) and those retained (cervix).
• Complications or additional work: If lysis of adhesions or other ancillary procedures were performed, document the additional work to support modifier 22 if applicable. Note that lysis of adhesions is typically bundled with major hysterectomy codes under NCCI edits; check the current edit table before billing it separately.

Submitting a clean claim for CPT 58180 starts with the operative note: It is the single document that determines whether the code survives audit. Build a pre-submission documentation review into the coding workflow before the claim leaves the practice.

Prior authorization for CPT 58180

Prior authorization requirements for CPT 58180 vary by payer and plan year. Medicare does not typically require prior authorization for hysterectomy procedures when performed in a facility setting, but Medicare Advantage plans operated by private insurers may impose their own authorization rules. Commercial payers, Medicaid managed-care organizations, and many state Medicaid fee-for-service programs commonly require authorization for all major gynecologic surgeries.

Using claims management software with built-in authorization tracking reduces the risk of submitting a 58180 claim without the required approval already on file. Typical payer criteria for approving 58180 include:

• Documentation of a confirmed diagnosis (leiomyoma, adenomyosis, or AUB) with at least one objective study (ultrasound, MRI, or hysteroscopy report)
• Evidence of failed conservative management, typically 3-6 months of hormonal therapy or other medical intervention
• A documented clinical discussion of alternatives (UAE, endometrial ablation) and reasons why supracervical hysterectomy is the appropriate intervention
• Operative urgency documentation if the case is scheduled with less than standard advance notice

Common denial reasons for CPT code 58180 and how to prevent them

CPT code 58180 denials cluster around four core failure patterns. Each one is preventable with a pre-submission workflow check. The table below maps each denial reason to its root cause and the corresponding fix.

Effective denial management workflows for surgical codes like 58180 require tracking the denial reason code (CARC) on every remittance advice, not just the payment amount. CARC codes identify whether a denial is a coding error, a documentation gap, or an authorization failure, each of which requires a different appeal strategy.

Modifiers and reimbursement optimization for CPT 58180

Four CPT modifiers apply most commonly to CPT code 58180 claims. Each requires specific documentation to withstand payer review.

• Modifier 22 (increased procedural services): Use when the procedure is significantly more complex than the typical 58180 encounter, for example, a heavily fibroid uterus with dense adhesions requiring substantially more operative time. Attach the full operative report and a cover letter documenting the additional time and complexity. Payers often request a comparison of typical vs actual operative time. Modifier 22 adds approximately 20-30% to reimbursement in many payer contracts, though the actual uplift varies.
• Modifier 51 (multiple procedures): Apply when a second separately payable surgical procedure is performed during the same operative session. The primary procedure (highest relative value) is paid at 100%; the secondary procedure is typically paid at 50% of the allowed amount. NCCI edit status must be confirmed before appending modifier 51 to any concomitant code.
• Modifier 62 (two surgeons): When CPT 58180 requires two surgeons operating simultaneously and each performs a distinct portion of the procedure, each surgeon bills 58180 with modifier 62. Each receives approximately 62.5% of the total allowed amount. Operative note must document the distinct role of each surgeon.
• Modifier 80 (assistant surgeon): When a second surgeon assists the primary surgeon and does not perform a distinct role, modifier 80 applies. Reimbursement for the assistant is typically 16% of the primary surgeon’s allowed amount. Some payers require pre-authorization for an assistant surgeon.

Conclusion

CPT code 58180 is a high-stakes billing code where the difference between a clean claim and a denial often comes down to four words in an operative note: “cervix was retained.” The code, the approach documentation, and the ICD-10-CM pairing must align before the claim leaves the practice.
