Is a D&C an Abortion? It Depends on the Reason

A dilation and curettage, commonly called a D&C, is a surgical procedure, not a diagnosis. Whether it counts as an abortion depends entirely on why it is performed. The same set of instruments, the same operating room, and the same surgical steps can be used to complete a miscarriage, remove tissue after childbirth, treat a molar pregnancy, diagnose abnormal uterine bleeding, or end an unwanted pregnancy. The procedure is identical; the medical context gives it its meaning. That distinction, straightforward in a clinical sense, has become legally and emotionally fraught in ways that affect real patients every day.

What a D&C Actually Involves

During a D&C, a clinician dilates the cervix and then removes tissue from the uterine lining. The “D” stands for dilation, which can be done with graduated metal rods, medication like misoprostol, or absorbent cervical dilators inserted hours beforehand. The “C” stands for curettage, the scraping or suctioning of uterine contents. In practice, many procedures labeled “D&C” today use suction rather than a sharp curette, or a combination of both. Some facilities use manual vacuum aspiration (MVA), which relies on a handheld syringe to generate suction instead of an electric pump.

Anesthesia varies. A study of patients undergoing D&C for pregnancy loss found that roughly seven in ten received general anesthesia, while the rest had sedation, and the choice was strongly influenced by where in the hospital the procedure took place.

D&C for Miscarriage

The single most common reason a D&C is performed on a pregnant person is to manage a miscarriage that has already occurred or is in progress. When a pregnancy stops developing but the body does not fully expel the tissue on its own, clinicians call it a missed or incomplete miscarriage. Left untreated, retained tissue can cause heavy bleeding, infection, or both. A D&C clears the uterus so healing can begin.

Not every miscarriage requires surgery. Some women choose expectant management, which means waiting for the body to pass the tissue naturally. Others take medication like misoprostol to speed the process along. A large trial published in the New England Journal of Medicine found that misoprostol led to complete expulsion by day eight in about 84 percent of cases, compared with a 3 percent failure rate with surgical management. Serious complications like hemorrhage or infection requiring hospitalization were rare in both groups, occurring in about 1 percent or fewer of patients.¹

When surgery is chosen, a Cochrane review of 59 trials involving over 12,000 women found that all surgical methods outperformed expectant management and medication for achieving complete miscarriage. Suction aspiration after cervical preparation ranked highest among surgical approaches.² In every one of these cases, the D&C is treating a pregnancy that has already failed. No viable pregnancy is being ended.

Research on fertility after a D&C for miscarriage is reassuring. A study of IVF patients found that D&C caused a small, temporary reduction in endometrial thickness within the first six months, but the effect was unlikely to affect future pregnancy rates compared with expectant management.³

D&C After Childbirth

A D&C can also follow a full-term delivery. When pieces of the placenta remain attached to the uterine wall after birth, the condition is called retained placenta. If manual removal fails, a D&C is used to clear the remaining tissue and prevent hemorrhage or infection. One study estimated that retained placenta requiring D&C occurs in roughly 3 out of every 1,000 deliveries and found a strong association with first-trimester bleeding earlier in the pregnancy.⁴ This use of D&C has nothing to do with ending a pregnancy. The baby has already been born.

D&C for Molar Pregnancy

A molar pregnancy, or hydatidiform mole, is an abnormal growth of tissue inside the uterus that results from a fertilization error. Instead of developing into a viable embryo, the cells form a mass that can grow quickly and, in rare cases, become cancerous. There is no baby to save. Suction curettage is the standard treatment, and prompt removal is important for monitoring whether the abnormal tissue has fully resolved.

A study of 118 patients with confirmed molar pregnancies found that suction curettage with misoprostol for cervical preparation was both safe and effective: no major complications like uterine perforation occurred, and the procedure averaged just over 15 minutes. The overall rate of post-molar gestational trophoblastic neoplasia, a condition requiring follow-up treatment, was about 14 percent, consistent with published rates.⁵

D&C for Diagnosis and Abnormal Bleeding

Outside of pregnancy entirely, D&C is used to investigate unexplained uterine bleeding, especially in women approaching or past menopause. A thin sample of the uterine lining is removed and examined under a microscope to check for polyps, hormonal imbalances, or precancerous and cancerous changes. In these cases, the patient may not be pregnant and may never have been recently pregnant. The procedure is purely diagnostic or therapeutic, addressing the uterine lining itself rather than a pregnancy.

When a D&C Is an Abortion

A D&C is used to end a pregnancy when the procedure is performed on a viable or potentially viable embryo or fetus and the intent is termination. In the first trimester, suction-based procedures are the most common surgical method of abortion worldwide. The mechanics are essentially identical to a D&C for miscarriage: dilate the cervix, evacuate the uterine contents. What differs is the starting point. In a miscarriage, the pregnancy has already failed or is failing. In an abortion, the pregnancy is ongoing.

For second-trimester terminations, a related but more involved procedure called dilation and evacuation (D&E) is typically used instead of a standard D&C. While the techniques overlap, D&E involves additional surgical instruments and wider dilation because of the larger gestational size. The two procedures are sometimes conflated in public discussion, but they are clinically distinct.

Same Procedure, Different Medical Codes

In medical billing and record-keeping, the procedure itself may look identical on paper, but the diagnosis code attached to it tells a completely different story. A D&C coded as treatment for an incomplete spontaneous abortion (miscarriage) carries a different diagnostic label than one coded as an elective termination. These codes matter for insurance coverage, legal compliance, and institutional reporting.

Research on abortion costs found that when private insurance or Medicaid covered an abortion, out-of-pocket costs dropped dramatically, to a median of $18 or $0 respectively. But many women’s insurance did not cover abortion at all, leaving a median out-of-pocket cost of $575.⁶ A D&C for miscarriage, by contrast, is typically covered as medically necessary care under most insurance plans without the same restrictions. The procedure is the same; the billing code is not.

How Abortion Laws Complicate Miscarriage Care

The overlap between abortion procedures and miscarriage procedures has created a real clinical problem in states with strict abortion bans. Because the surgical technique is identical, physicians in restricted states face legal uncertainty when treating patients whose pregnancies are failing but have not yet definitively ended. The question “is this an abortion?” does not always have a clean answer at the bedside, and the legal consequences of getting it wrong can include criminal prosecution.

A qualitative study published in JAMA Network Open found that across clinical scenarios, physicians reported delays in treatment driven by legal uncertainty. In early pregnancy loss, abortion bans compelled additional and sometimes unnecessary confirmatory testing, such as repeat ultrasounds or serial blood draws, to prove a pregnancy was nonviable before intervening, even when the clinical picture was already clear.⁷

A separate study of obstetrics-gynecology residency programs found that institutional abortion restrictions were the strongest predictor of rigid reliance on imaging guidelines before diagnosing early pregnancy loss. Programs in states with hostile abortion policies were far less likely to use mifepristone for miscarriage management and less likely to offer office-based suction aspiration. After controlling for other program characteristics, institutional abortion restrictions were the only significant predictor of overly rigid diagnostic criteria, with an odds ratio over 12.⁸

The practical effect is that patients experiencing miscarriage in restrictive states may wait longer for treatment, undergo more tests, and have fewer options available to them than patients in other states, all because the tools used to manage their miscarriage are the same tools used for abortion. Surveys of OBGYNs have found that roughly one in five nationally report feeling constrained in providing miscarriage care since the Dobbs ruling, with the figure much higher among physicians practicing in states with bans.

Risks of the Procedure Regardless of Reason

Whether performed for miscarriage, abortion, molar pregnancy, or any other indication, a D&C carries a small set of potential complications. The most discussed long-term risk is Asherman syndrome, a condition where scar tissue forms inside the uterus and can cause menstrual changes, pain, or difficulty with future pregnancies. A large study of over 2,500 women who underwent uterine curettage after abortion found an Asherman syndrome rate of about 1.6 percent. The main risk factor was having three or more prior abortions, which increased the odds roughly fivefold. The type of instrument used, whether vacuum aspiration or sharp curettage, did not significantly change the risk.⁹

Short-term complications include heavy bleeding, infection, and in rare cases uterine perforation, where a surgical instrument passes through the uterine wall. These complications are uncommon, and serious adverse events requiring hospitalization occur in about 1 percent or fewer of cases regardless of whether the procedure is done for miscarriage or termination.

Newer Alternatives to Traditional D&C

Sharp curettage, the oldest version of the procedure, is gradually being replaced in many settings. Manual vacuum aspiration and electric vacuum aspiration both achieve the same goal with less tissue trauma and fewer complications. A randomized trial comparing all three methods for miscarriage found that MVA and traditional D&C were equally effective at complete evacuation, but MVA resulted in less blood loss, shorter procedure times, and fewer complications.¹⁰ A study of 200 women managed for incomplete miscarriage similarly found that both MVA and D&C achieved complete evacuation without the need for repeat procedures, but MVA had a lower complication rate.¹¹

In many lower-resource settings globally, the shift away from traditional D&C has been driven by both safety and logistics. MVA does not require electricity, general anesthesia, or an operating room, which makes it practical for clinics without surgical infrastructure. An initiative in Pakistan replaced D&C with MVA and medical abortion across selected public hospitals for incomplete-abortion management.¹² Medical management using misoprostol alone has also reduced the need for surgical intervention after spontaneous abortion.¹³

The Same Tool in a Political Tug-of-War

The dual-use nature of uterine evacuation technology has created friction that extends well beyond the United States. In Senegal, where abortion is legally restricted, MVA was promoted by health authorities as the preferred technology for treating complications of incomplete miscarriage, a use classified as post-abortion care. But because the same device can terminate a pregnancy, the primary international donor for this program, USAID, restricted its purchase. Concerns about off-label use of MVA for termination contributed to some facilities continuing to rely on older and less effective methods, including sharp curettage and even digital curettage, where a provider uses a finger to remove uterine tissue.¹⁴ The result is a situation where the political classification of a tool affects which patients can access it, even when the intended use is universally accepted as legitimate medical care.

The Emotional Weight of the Label

For patients, the question of whether their D&C “counts” as an abortion can carry enormous emotional significance. A woman who wanted her pregnancy and lost it to miscarriage may be deeply distressed to learn that the same procedure code or legal category applies to her care. Research on pregnancy loss of all types, including miscarriage, abortion, and fetal death, finds that most women experience anxiety, stress, and symptoms of depression afterward, though the individual response varies depending on factors like age, culture, and personal beliefs.¹⁵

The language around these procedures can add to the confusion. In medical terminology, the word “abortion” historically referred to any pregnancy that ended before viability, whether spontaneous (miscarriage) or induced (termination). Medical records may still use terms like “spontaneous abortion” or “missed abortion” for what most people would call a miscarriage. When a patient sees “abortion” on their chart after a devastating pregnancy loss, the clinical shorthand can feel like a gut punch. Some hospitals and medical systems have begun shifting to terms like “pregnancy loss” or “early pregnancy failure” in patient-facing communication, though the older terminology persists in coding systems and medical literature.

For patients undergoing elective termination, the emotional landscape is different but not necessarily simpler. Relief, grief, guilt, and practical resolve can all coexist. The psychological impact of an abortion depends heavily on circumstances, including whether the decision was freely made, whether the person had social support, and whether the pregnancy was wanted but ended for medical reasons. A D&C performed because of a severe fetal anomaly diagnosed at 12 weeks occupies a gray zone that resists tidy labels: it is technically an induced termination, but it may feel nothing like the public image of “getting an abortion.”

How the Molar Pregnancy Case Blurs Lines Further

Molar pregnancies occupy a particularly uncomfortable position in this debate. A complete mole contains no embryonic tissue at all; it is a mass of abnormally growing placental cells. A partial mole may contain some fetal tissue, but the pregnancy is never viable and poses a cancer risk to the patient. Evacuation is medically urgent. Yet because molar pregnancy involves the products of conception and requires uterine evacuation, it can technically fall under abortion-adjacent legal categories in some jurisdictions. A case report of a woman who underwent suction curettage for a partial mole documents not only the procedure itself but also subsequent complications including intrauterine adhesions.¹⁶ The clinical reality is that delaying evacuation of a molar pregnancy to navigate legal requirements puts the patient at real risk of a rare but serious cancer. No reasonable medical framework treats molar evacuation as an abortion, but the procedural overlap means the distinction sometimes has to be argued rather than assumed.
