CPT code 59840 – Induced abortion by dilation and curettage

Key takeaways

CPT 59840 covers induced abortion by dilation and curettage, including suction curettage, and is normally used in the first trimester (under 14 weeks).

ICD-10-CM Z33.2 is the primary diagnosis code for an elective termination encounter, and the O04 series applies only when complications are documented.

CMS assigns a 10-day global period to CPT 59840, so routine follow-up within 10 days is bundled and cannot be billed separately.

Pabau, the practice management platform we build, submits 59840 claims through Claim.MD, checks eligibility in real time, tracks claim status, and posts ERA remittances.

CPT code 59840: Official descriptor and procedure overview

CPT code 59840 describes “induced abortion, by dilation and curettage.” The provider dilates the cervix and empties the uterus with a curette, and that includes suction curettage (vacuum aspiration). The procedure is usually performed in the first trimester, under 14 weeks, but the descriptor sets no trimester limit.

The American Medical Association maintains it in the maternity care and delivery subsection (59000-59899).

Key clinical components bundled within 59840:

• Cervical dilation using mechanical dilators
• Curettage of the uterine cavity, by sharp or suction curettage
• Routine intraoperative monitoring and standard post-procedure recovery observation
• Surgeon’s pre-procedure evaluation on the same date of service

The code is billable under standard AMA CPT coding rules for Part B professional services. Facility and non-facility settings each carry separate reimbursement rates from CMS.

CPT 59840 vs. 59820 vs. 59841 vs. 58120: How to choose the right code

These four codes share overlapping terminology but describe clinically and legally distinct procedures. Selecting the wrong one is the most common cause of payer rejections on obstetric D&C claims.

Key distinction: 59840 requires an active, ongoing pregnancy with documented intent to terminate. 59820 applies only when the fetus has already died (missed abortion). 59841 is for dilation and evacuation, which is usually a second-trimester procedure. 58120 applies to non-pregnant patients undergoing D&C for gynecologic indications such as abnormal uterine bleeding or polyps.

The chart below turns that choice into three questions, asked in the order a coder reads the operative note.

Accepted ICD-10-CM diagnosis codes for CPT 59840

Every CPT 59840 claim requires a supporting ICD-10-CM diagnosis code. Payer systems run automated medical necessity edits against these pairings before adjudication.

Important: Several state Medicaid programs restrict which ICD-10-CM codes are reimbursable for induced abortion procedures and which need separate prior authorization. Check the payer’s accepted code list before submitting.

Z33.2 fits an uncomplicated elective procedure, while an O04 code belongs on a claim that documents a complication. Hemorrhage after the procedure is O04.6, not O04.81. Verify every code against the current tabular list in the CDC/NCHS ICD-10-CM web tool.

Modifiers and when to apply them

Modifiers change how CPT 59840 is adjudicated without altering the procedure code itself. Incorrect modifier use is a leading cause of payer downcoding and post-payment audits. Modifier -59 is checked against National Correct Coding Initiative (NCCI) edits, which flag code pairs that are normally bundled.

Modifier -22 requires a written addendum to the operative report explaining the specific factors that increased complexity. Without it, payers will process 59840 at the standard rate and deny the upcharge. Many commercial payers require a separate appeal with supporting documentation before paying any -22 increase.

The 10-day global surgical package

CPT 59840 carries a 10-day global surgical period under the CMS Medicare Physician Fee Schedule. All routine follow-up care within 10 days of the procedure date is bundled into the 59840 payment and cannot be billed separately.

What the global package includes:

• The procedure itself and immediate post-procedure recovery
• Routine evaluation and management (E/M) visits within 10 days that are directly related to the procedure
• Typical post-procedure complications managed without a return to the operating room (OR)

What can be billed separately during the global period:

• Complications requiring a return to the OR, such as uterine perforation repair, with modifier -78
• Unrelated E/M services, with modifier -24 and a distinct ICD-10-CM code
• Anesthesia services, which are always separately reportable (see below)

Anesthesia billing: Anesthesia for CPT 59840 is not bundled into the surgical global package. The anesthesia provider reports it separately with 01966, the anesthesia code for induced abortion procedures. The surgeon’s 59840 claim and the anesthesiologist’s claim are adjudicated independently. Coordinate submission so payer systems don’t flag them as duplicate services.

Documentation requirements for CPT 59840

A complete operative report is the minimum documentation threshold for any 59840 claim. Missing or vague documentation is the second most common denial driver after incorrect diagnosis code pairing. A pre-submission checklist built on the elements below catches most of these errors before the claim goes out.

Required documentation elements:

• Gestational age confirmation: Ultrasound dating or the last menstrual period (LMP), documented in the record
• Informed consent: A signed consent form covering procedure risks, alternatives, and patient acknowledgment
• Procedure technique: An operative note specifying the dilation method, the curettage technique (sharp or suction), and completeness of evacuation
• Clinical indication: The reason for the procedure, referenced by the ICD-10-CM code submitted
• State-specific mandates: Some states require waiting periods, counseling documentation, or specific consent language. Confirm the rules for your jurisdiction before the procedure date.

A CPT 59840 claim submitted without gestational age documentation will be denied by most payers as underdocumented. Ultrasound confirmation is the cleanest supporting document because it provides objective dating.

Payer requirements and prior authorization

Prior authorization requirements for CPT 59840 vary significantly by payer and by state, so this is where proactive checks prevent the most denials. OB/GYN practices billing this code also need to stay current on medical billing compliance rules for reproductive health.

• Commercial payers: Most large commercial payers do not require prior authorization for CPT 59840 when the member’s plan covers it. Coverage itself is not universal, so verify benefits before scheduling.
• Medicaid: Coverage varies by state. Some states cover CPT 59840 broadly, while others fund procedures only in cases of rape, incest, fetal anomaly, or life endangerment of the mother. Always check the specific state Medicaid fee schedule. California’s Department of Health Care Services (DHCS) and New Mexico’s Human Services Department (HSD) publish reproductive health billing guidance that applies to 59840.
• Medicare: Medicare coverage for elective induced abortion is highly restricted under the Hyde Amendment. Medicare covers induced abortion only in cases of rape or incest, or when the mother’s life is endangered. Claims submitted outside these statutory criteria will be denied, so do not bill 59840 to Medicare Part B for elective procedures.

CPT 59840 reimbursement: Medicare and Medicaid rates

Reimbursement for CPT 59840 under Medicare and Medicaid reflects the procedure’s relative value unit (RVU) weighting and geographic adjustment factors. Use the CMS Physician Fee Schedule look-up tool to retrieve current national facility and non-facility payment amounts for 59840. For detailed RVU component breakdowns, FastRVU’s 2026 RVU lookup provides work, practice expense, and malpractice RVU values by code.

State Medicaid rates for CPT 59840 are set independently by each state’s Medicaid agency and can differ substantially from Medicare rates. States that cover the procedure broadly, such as California and New Mexico, typically publish fee schedule amounts in their provider manuals. Practices serving high Medicaid volumes should pull current state-specific rates before setting patient estimates.

Common denial reasons and how to prevent them

CPT 59840 generates denials across a predictable set of failure points. Structured denial management workflows that address each of these before submission cut the rework cycle significantly.

How practice management software simplifies CPT 59840 billing

CPT 59840 billing concentrates several risk factors in one code. Payer-specific authorization, state Medicaid variation, ICD-10-CM pairing, the 10-day global period, and NCCI edits each need their own check. Without software that connects the clinical and billing sides, staff manage those checks by hand across different systems.

Pabau’s claims management software handles the submission side of that workflow. Claims go to payers electronically through the Claim.MD clearinghouse, so nobody re-keys 59840 into a separate portal. Real-time eligibility checks confirm the patient’s coverage before the procedure date, while there is still time to act.

Claim status tracking shows where each submission stands after it leaves the practice. Payments arrive as electronic remittance advice (ERA), which Pabau posts against the claim. When a payer denies 59840, the ERA carries a claim adjustment reason code (CARC), and our guide to medical billing denial codes explains each one.

Conclusion

Claims for CPT 59840 rarely fail on the procedure itself. They fail when the record can’t show the technique, the gestational age, or the payer’s coverage terms.

So put the checks before the claim. Confirm coverage and any prior authorization at scheduling, code the technique the operative note describes, and save O04 codes for documented complications. That front-loaded work takes minutes per case, and it costs far less than reworking a denied claim.

Pabau handles the submission side, with electronic claims through Claim.MD, real-time eligibility checks, claim status tracking, and ERA posting in one place. Book a demo to see how Pabau keeps OB/GYN claims for codes like 59840 moving from submission to payment.
