The CPT® Code 46045 refers to the procedure of incision and drainage of an intramural, intramuscular, or submucosal abscess located in the anal region, performed transanally and under anesthesia. An intramural abscess is defined as one that is situated within the substance of the anal wall, while an intramuscular abscess occurs within the muscle tissue of the anal sphincter or the levator ani muscles. A submucosal abscess, on the other hand, is found just beneath the mucosal layer of the anus, within the submucosal tissue. The procedure typically begins with a digital examination to accurately identify the location of the abscess. Once located, a radial or cross-shaped incision is made over the most prominent part of the abscess or the area exhibiting the greatest fluctuance. This incision allows for the excision of the edges to expose the abscess cavity, facilitating wide drainage. During the procedure, the abscess cavity is manually inspected, and any loculations, or pockets of pus, are broken up to ensure complete drainage. After the drainage is accomplished, the incisions may be left open to allow for continued drainage, packed with iodophor gauze for a duration of 24 hours, or a drain may be placed to assist in the management of the abscess.

The procedure described by CPT® Code 46045 is indicated for the treatment of various types of abscesses located in the anal region. These indications include:
The procedure for incision and drainage of an abscess as described by CPT® Code 46045 involves several critical steps:
Post-procedure care following the incision and drainage of an abscess involves monitoring the site for signs of infection and ensuring proper drainage. Patients may be advised to keep the area clean and dry, and to follow any specific instructions regarding dressing changes or the care of any drains placed. Pain management may also be addressed, and patients should be informed about signs of complications, such as increased redness, swelling, or fever, which would necessitate further medical evaluation. Follow-up appointments may be scheduled to assess healing and ensure that the abscess has resolved completely.

| 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. | 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). | 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. | 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.) | AG | Primary physician | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | GC | This service has been performed in part by a resident under the direction of a teaching physician |
