Official Description

Drainage of abscess, cyst, hematoma from dentoalveolar structures

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 41800 involves the drainage of an abscess, cyst, or hematoma specifically from the dentoalveolar structures. The term "dentoalveolar" refers to the anatomical components associated with the teeth and their supporting structures, which include the periapical region (the area surrounding the apex of a tooth root), dental pulp (the innermost part of the tooth containing nerves and blood vessels), periodontal region (which consists of the periodontal ligaments that attach the tooth to the alveolar bone), and the gums that encase the teeth. During this procedure, if necessary, the affected tooth may be extracted to facilitate access to the abscess, cyst, or hematoma. The clinician will expose the lesion, making an incision to allow for drainage. This process may involve breaking up any loculations, or compartments, within the abscess or cyst to ensure complete drainage. Additionally, any blood clots present in the hematoma are removed to promote healing. After the drainage is completed, the incision may be left open to allow for continued drainage or may be packed with gauze to assist in the healing process and prevent further complications.

1. Indications

The procedure is indicated for the following conditions:

  • Abscess A localized collection of pus that can cause pain, swelling, and infection in the dentoalveolar structures.
  • Cyst A fluid-filled sac that can develop in the dental area, potentially leading to discomfort or infection.
  • Hematoma A localized collection of blood outside of blood vessels, which can occur in the dentoalveolar region and may require drainage to alleviate pressure and promote healing.

2. Procedure

The procedure involves several key steps to effectively drain the abscess, cyst, or hematoma:

  • Step 1: Assessment and Preparation The clinician begins by assessing the affected area, determining the need for drainage based on the presence of an abscess, cyst, or hematoma. The patient is prepared for the procedure, which may include administering local anesthesia to minimize discomfort.
  • Step 2: Incision and Exposure Once the area is adequately anesthetized, the clinician makes an incision to expose the abscess, cyst, or hematoma. This incision is strategically placed to allow for optimal drainage while minimizing trauma to surrounding tissues.
  • Step 3: Drainage After exposure, the clinician drains the contents of the abscess, cyst, or hematoma. This may involve breaking up loculations within the abscess or cyst to ensure complete evacuation of the material. In the case of a hematoma, any blood clots are carefully removed to facilitate proper drainage.
  • Step 4: Post-Drainage Care Following the drainage, the incision may be left open to allow for continued drainage of any residual fluid or may be packed with gauze to promote healing and prevent closure of the incision too soon.

3. Post-Procedure

After the procedure, the patient may be monitored for any signs of complications, such as infection or excessive bleeding. Instructions for care at home may include keeping the area clean and dry, managing pain with prescribed medications, and attending follow-up appointments to ensure proper healing. The clinician may also provide guidance on when to seek further medical attention if symptoms worsen or do not improve.

X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period
GC This service has been performed in part by a resident under the direction of a teaching physician
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).
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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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.
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.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 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.)
