CPT code 59160 – Postpartum curettage

Key takeaways

CPT code 59160 reports postpartum curettage after a completed delivery, and it sits in the Excision subsection (59100-59160) of Maternity Care and Delivery.

Sharp and suction curettage both report as 59160, while hysteroscopic sampling goes to 58558 and nonobstetric D&C goes to 58120.

Pregnancy-related curettage before a delivery is never 59160, so report 59812 for an incomplete abortion and 59820 or 59821 for a missed abortion.

Inside the delivery’s global package, add modifier -78 or -79 according to the payer’s policy, or expect a bundling denial.

The 2026 Medicare national rate is about $263.53 in the office and $167.67 in a facility, with a 10-day global period.

CPT code 59160 covers curettage after a completed delivery

CPT code 59160 reports postpartum curettage, the scraping or suctioning of the uterus after a completed delivery. It sits in the Excision subsection (59100-59160) of Maternity Care and Delivery, in the Surgery section of the AMA CPT codebook. The official descriptor reads: Curettage, postpartum.

Those two words cover a lot of ground. In practice, 59160 is reported when retained placental tissue or postpartum bleeding sends the patient back for a curettage. The approach doesn’t change the code.

• Code range: 59160 sits within the 59000-59899 Maternity Care and Delivery section of CPT.
• Procedure category: Excision subsection (59100-59160) of Maternity Care and Delivery.
• Approach neutrality: Sharp curettage and suction (vacuum) curettage both report as 59160.
• Postpartum requirement: The delivery must be complete. The code never applies to managing a miscarriage or an abortion.
• Global period: 10 days under the 2026 Medicare Physician Fee Schedule.

A completed delivery is the line 59160 never crosses

The scope of 59160 starts once a delivery is complete. Use the table below to check whether a scenario belongs to it or to a neighboring code.

The deciding fact is a completed delivery. If the pregnancy ended in an incomplete abortion, report 59812. A missed abortion goes to 59820 or 59821. If the patient isn’t pregnant and hasn’t recently delivered, the D&C is nonobstetric and 58120 applies.

Five details the operative note has to prove

Payer auditors look for five elements in the operative note before they pay a 59160 claim. If one is missing, expect a records request or a medical necessity denial.

• Postpartum timing: State the delivery date and confirm the procedure happened in the postpartum period. “Day 3 postpartum” works. “Recent delivery” doesn’t.
• Clinical indication: Name it plainly, such as retained placental tissue, hemorrhage not controlled by oxytocics, or endometritis with retained products. The primary ICD-10 code must match this narrative.
• Instrument used: Record sharp curettage (curette type and size) or suction curettage (cannula size and pressure).
• Estimated blood loss: Required for hemorrhage-related cases, because it supports medical necessity.
• Attending attestation: In teaching hospitals, the attending must attest to performing or directly supervising the key portion.

Good medical billing compliance means these elements live in a structured operative note template. They get captured before the case closes, not rebuilt from memory after a denial.

Diagnosis codes that justify postpartum curettage

The primary diagnosis is another frequent denial trigger for 59160. The ICD-10-CM code has to match the indication in the operative note, so check it against the CDC ICD-10-CM tool.

Always assign the most specific code available. O72.2 is the correct primary when retained products cause bleeding after 24 hours, a common outpatient 59160 scenario. Some payers also limit which diagnoses support the procedure, so check your MAC’s LCD database before billing.

59160, 58120, 59812 and 58558 split on timing and approach

Four neighboring codes are the usual mix-ups with CPT code 59160. They differ on obstetric context, surgical approach and global period, as the AAPC CPT code reference and AMA descriptors show.

The chart below puts the choice in the order a coder should ask the questions.

59160 vs 58120: 58120 is strictly nonobstetric, so pregnancy-related curettage never belongs there. Curettage for retained products after a miscarriage goes to 59812, or to 59820 or 59821 for a missed abortion. A curettage on day 5 after a term vaginal delivery is 59160.

59160 vs 59812: Both codes sit in Maternity Care and Delivery, but they cover different events. 59812 completes an incomplete abortion. 59160 treats a new complication after a delivery is complete.

Modifier -78 or -79 decides whether 59160 escapes the delivery global

CPT code 59160 carries its own 10-day global period. The harder question is whether it pays while the patient is still inside the global package of her delivery code.

The global obstetric package covers antepartum care, the delivery and routine postpartum care. It applies to delivery codes such as 59400 and 59510. A curettage for a distinct postpartum complication is generally reported on top of that package, and payers expect a modifier to show why.

• Modifier -78 (unplanned return to the OR, related procedure): Many payers want it when the curettage treats a delivery complication in the OR.
• Modifier -79 (unrelated procedure, same postoperative period): Some payers ask for it instead, treating the curettage as separate from delivery care.
• Modifier -24 (unrelated E/M, same postoperative period): Used on E/M visits before the curettage decision, when those visits also fall inside the delivery global.
• Payer variation: The choice between -78 and -79 depends on payer policy. Check each payer’s rules before you bill.

A missing global-period modifier is one of the most common reasons 59160 denies. The payer sees the delivery global still open, bundles the curettage into it and denies the line.

2026 Medicare pays about $264 for 59160 in the office

The 2026 Medicare Physician Fee Schedule (MPFS) sets national rates for 59160, adjusted locally by Geographic Practice Cost Indices (GPCI).

The table shows national unadjusted figures at the 2026 conversion factor of $33.4009. Use the CMS MPFS look-up tool to pull your locality rate.

Check current figures with the FastRVU RVU look-up tool, which mirrors the CMS 2026 file. Rates change every January 1 and vary by locality. Medicaid rates are set by each state, and many commercial payers pay a percentage of Medicare.

Anesthesia for 59160 is billed separately by the anesthesiologist under the appropriate anesthesia codes. The surgeon doesn’t bill it. Record the anesthesia type in the operative note, but submit only 59160 under the surgeon’s NPI.

How a 59160 claim moves, and where it stalls

Here’s the path a postpartum curettage claim takes, with the step where each problem usually shows up.

1. Operative note signed: The surgeon documents timing, indication, instrument and blood loss. A note without timing stalls the claim later.
2. Charge entry: The biller enters 59160 with the date of the curettage, not the delivery date. A superbill tied to the operative note keeps the code and diagnosis in step.
3. Global check: The biller checks whether the same provider’s delivery global is still open. If it is, the payer’s preferred modifier goes on the line.
4. Diagnosis pairing: The primary O-chapter code goes first, matched to the documented indication.
5. Scrub and submit: The clearinghouse checks the claim format and sends it to the payer.
6. Remittance: The electronic remittance advice (ERA) posts the payment or the denial reason, and denials go to the work queue.

Example: A patient returns on day 9 after a vaginal delivery with heavy bleeding. Ultrasound shows retained tissue, and the obstetrician performs a suction curettage in the OR. Report 59160 with O72.2 as the primary diagnosis. Because the delivery global is still open, add -78 or -79 according to the payer’s policy.

Run this checklist before you submit a 59160 claim

• The note states the delivery date and the postpartum day of the procedure.
• The delivery is complete, so 59812, 59820, 59821 and 58120 don’t apply.
• The primary diagnosis is a postpartum O-chapter code that matches the indication.
• The payer’s preferred modifier (-78 or -79) is on the line if the delivery global is open.
• Estimated blood loss is documented for any hemorrhage case.
• The date of service is the day of the curettage.
• The claim goes out inside the payer’s timely filing limit.

Most 59160 denials trace back to five fixable errors

Five denial patterns come up again and again on 59160 claims. Each has a clear fix, and these denial management steps apply to Medicare and commercial payers alike. For what each code means, keep a billers’ CARC reference open.

It’s cheaper to send a clean claim than to win an appeal. Same-day charge capture and a second look at the modifier and diagnosis cut first-pass denials on postpartum curettage.

How Pabau keeps postpartum curettage claims complete

Most 59160 rework starts at charge entry, when someone retypes dates and codes from the chart. Pabau, the practice management platform we build, pre-fills each claim from the patient record instead. Its claims software for practices also checks that required claim fields are filled in before submission.

ICD-10 and CPT lookup libraries help coders confirm 59160 and the right O-chapter code without leaving the record. For US practices, the Claim.MD integration adds eligibility checks, claim tracking, ERA posting and CMS-1500 export. Billing staff can see where each claim stands and post the payment when it lands.

Conclusion

Treat the delivery date as the first field you check on any postpartum curettage claim. If the patient delivered, 59160 is the code. The remaining work is proving the complication and choosing the modifier your payer expects.

If she didn’t deliver, you’re looking at 59812, 59820, 59821 or 58120, and no modifier will rescue the wrong code. A couple of extra minutes at charge entry cost far less than an appeal on a claim worth about $264.
