Official Description

Anorectal exam, surgical, requiring anesthesia (general, spinal, or epidural), diagnostic

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 45990 refers to a surgical anorectal examination that necessitates the use of anesthesia, which can be general, spinal, or epidural. While anesthesia is not commonly required for standard anorectal examinations, it becomes essential in cases where patients experience significant discomfort or exhibit extreme anxiety regarding the procedure. This examination is primarily conducted to diagnose underlying issues causing pain in the anorectal area. During the procedure, the patient is typically positioned in a left lateral or Sim's position to facilitate access and visualization of the perineal region. The physician begins by visually inspecting the area for any lesions, fissures, hemorrhoids, drainage, or other abnormalities that may be present. Following the visual inspection, a digital examination is performed to assess for any masses or areas of fluctuance, which could suggest the presence of an abscess. Additionally, the use of an anoscope or proctoscope equipped with a sufficient light source allows for a more detailed visualization of the anal canal and distal rectum, enabling the physician to identify any lesions, masses, fistulas, or other abnormalities that may require further investigation or intervention.

1. Indications

The procedure described by CPT® Code 45990 is indicated for patients who present with specific symptoms or conditions related to the anorectal region. These indications may include:

  • Significant Pain: Patients experiencing severe discomfort in the anorectal area may require this examination to identify the underlying cause.
  • Apprehension: Individuals who are extremely anxious about the examination may benefit from the use of anesthesia to facilitate the procedure.
  • Suspected Lesions: The presence of suspected lesions, fissures, or hemorrhoids necessitates a thorough examination to confirm diagnosis and determine appropriate treatment.
  • Drainage: Any abnormal drainage from the anorectal area may warrant this diagnostic procedure to assess for potential infections or other issues.
  • Masses or Fluctuance: The detection of masses or areas of fluctuance during a preliminary examination may indicate the need for further investigation through this procedure.

2. Procedure

The procedure for CPT® Code 45990 involves several critical steps to ensure a comprehensive examination of the anorectal area. These steps include:

  • Step 1: Anesthesia Administration - The procedure begins with the administration of anesthesia, which may be general, spinal, or epidural, depending on the patient's needs and the physician's assessment. This step is crucial for minimizing discomfort and anxiety during the examination.
  • Step 2: Patient Positioning - The patient is positioned in a left lateral or Sim's position, which provides optimal access to the perineal region for examination. This positioning is essential for both the comfort of the patient and the effectiveness of the procedure.
  • Step 3: Visual Inspection - The physician conducts a thorough visual inspection of the perineal region, looking for any signs of lesions, fissures, hemorrhoids, drainage, or other abnormalities. This initial assessment is vital for identifying potential issues that may require further evaluation.
  • Step 4: Digital Examination - Following the visual inspection, the physician performs a digital examination to assess for any masses or areas of fluctuance. This step helps to identify potential abscesses or other significant findings that may not be visible externally.
  • Step 5: Use of Anoscope or Proctoscope - To enhance visualization, the physician may utilize an anoscope or proctoscope equipped with a good light source. This tool allows for a detailed examination of the anal canal and distal rectum, enabling the identification of lesions, masses, fistulas, or other abnormalities that may require further intervention.

3. Post-Procedure

After the completion of the anorectal examination, patients may require specific post-procedure care to ensure proper recovery and monitoring. It is essential to observe the patient for any immediate adverse reactions to the anesthesia administered. Patients may experience some discomfort or soreness in the anorectal area following the procedure, which can typically be managed with over-the-counter pain relief medications as advised by the physician. Additionally, the physician may provide instructions regarding activity restrictions, dietary modifications, or follow-up appointments based on the findings of the examination. It is crucial for patients to report any unusual symptoms, such as excessive bleeding, severe pain, or signs of infection, to their healthcare provider promptly.

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).
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.
GC This service has been performed in part by a resident under the direction of a teaching physician
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.)
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).
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.
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.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
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.
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).
