Official Description

Dilation and curettage, diagnostic and/or therapeutic (nonobstetrical)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 58120 refers to a dilation and curettage (D&C) that is performed for diagnostic and/or therapeutic purposes in a nonobstetrical context. This procedure involves several critical steps aimed at accessing the uterine cavity for examination and treatment. Initially, a speculum is inserted into the vagina to allow visualization and access to the cervix. The cervix is then cleansed with an antiseptic solution to minimize the risk of infection. A tenaculum, a surgical instrument with a hook-like end, is used to grasp the anterior lip of the cervix, providing stability during the procedure. To assess the depth and angle of the uterus, a sound—a thin, rod-like instrument—is passed through the cervix. This step is crucial for ensuring that the subsequent dilation is performed safely and effectively. The cervix is numbed to reduce discomfort, and dilation is achieved by inserting a series of metal rods, known as dilators, which gradually increase in diameter. Alternatively, a laminaria tent may be utilized, which is a type of absorbent material inserted into the cervix hours before the procedure. As the laminaria absorbs moisture, it expands, gently dilating the cervical canal over time. During the D&C, biopsies may be taken from the endocervical canal to obtain tissue samples for further examination. A curette, a surgical instrument designed for scraping, is then inserted through the cervix to scrape or suction the uterine wall, allowing for the removal of tissue. The collected endocervical and endometrial tissue is subsequently sent for pathology examination to assess for any abnormalities. After the procedure is completed, the tenaculum is removed, and any bleeding from the cervix is managed through the application of pressure, ensuring patient safety and comfort.

1. Indications

The dilation and curettage procedure (CPT® Code 58120) is indicated for various clinical scenarios where diagnostic or therapeutic intervention is necessary. The following conditions may warrant the performance of this procedure:

  • Abnormal Uterine Bleeding - This procedure may be performed to investigate the cause of irregular or excessive bleeding from the uterus.
  • Endometrial Hyperplasia - D&C can be used to obtain tissue samples for diagnosis and treatment of thickened endometrial lining.
  • Uterine Polyps - The procedure allows for the removal and examination of polyps that may be causing symptoms.
  • Miscarriage Management - D&C may be indicated for the evacuation of retained products of conception following a miscarriage.
  • Endometrial Cancer Screening - The procedure is utilized to obtain endometrial tissue for pathological evaluation to rule out malignancy.

2. Procedure

The dilation and curettage procedure involves several key steps that ensure effective access to the uterine cavity for diagnostic and therapeutic purposes. The following procedural steps are typically followed:

  • Step 1: Preparation - The patient is positioned appropriately, and a speculum is inserted into the vagina to allow for visualization of the cervix. The cervix is then cleansed with an antiseptic solution to reduce the risk of infection.
  • Step 2: Cervical Stabilization - A tenaculum is applied to the anterior lip of the cervix. This instrument helps stabilize the cervix during the procedure, allowing for better access to the uterine cavity.
  • Step 3: Uterine Measurement - A sound is passed through the cervix to measure the depth and angle of the uterus. This step is crucial for ensuring that the subsequent dilation is performed safely.
  • Step 4: Cervical Dilation - The cervix is numbed to minimize discomfort, and dilation is achieved by inserting a series of metal rods of increasing diameter into the cervical canal. Alternatively, a laminaria tent may be inserted into the cervix 8-20 hours prior to the procedure to facilitate gradual dilation.
  • Step 5: Tissue Sampling - Once the cervix is adequately dilated, a curette is inserted through the cervix to scrape or suction the uterine wall. This allows for the collection of endocervical and endometrial tissue samples for pathological examination.

3. Post-Procedure

After the completion of the dilation and curettage procedure, the tenaculum is carefully removed. It is important to monitor the patient for any signs of complications, such as excessive bleeding or infection. The healthcare provider may apply pressure to the cervix to control any bleeding that may occur. Patients are typically advised to rest and may be given specific instructions regarding activity restrictions and follow-up appointments. Additionally, the results of the pathology examination will guide any further treatment or management needed based on the findings from the collected tissue samples.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
GC This service has been performed in part by a resident under the direction of a teaching physician
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
47 Anesthesia by surgeon: regional or general anesthesia provided by the surgeon may be reported by adding modifier 47 to the basic service. (this does not include local anesthesia.) note: modifier 47 would not be used as a modifier for the anesthesia procedures.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
73 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure prior to the administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may cancel a surgical or diagnostic procedure subsequent to the patient's surgical preparation (including sedation when provided, and being taken to the room where the procedure is to be performed), but prior to the administration of anesthesia (local, regional block(s) or general). under these circumstances, the intended service that is prepared for but cancelled can be reported by its usual procedure number and the addition of modifier 73. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
