Official Description

Intraoral incision and drainage of abscess, cyst, or hematoma of tongue or floor of mouth; submandibular space

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 41008 refers to the procedure of intraoral incision and drainage of an abscess, cyst, or hematoma specifically located in the submandibular space of the mouth. This procedure is essential for addressing infections or fluid accumulations that can occur in the deep fascial spaces surrounding the mandible, which is the lower jawbone. The submandibular space is anatomically defined as extending from the hyoid bone to the mucosal layer in the floor of the mouth, bordered anteriorly and laterally by the mandible and inferiorly by the superficial layer of the deep cervical fascia. The procedure involves making an incision in the mouth to access these deep spaces, allowing for the drainage of the pathological fluid. The drainage process includes exposing the abscess, cyst, or hematoma, opening it, and ensuring that any compartments within the abscess or cyst are disrupted to facilitate complete drainage. Additionally, any blood clots present in a hematoma are removed, and drains may be placed as necessary to prevent re-accumulation of fluid. This procedure is critical for alleviating pain, preventing further complications, and promoting healing in patients with these conditions.

1. Indications

The procedure described by CPT® Code 41008 is indicated for the following conditions:

  • Abscess - A localized collection of pus that can cause swelling, pain, and infection in the submandibular space.
  • Cyst - A fluid-filled sac that can develop in the submandibular area, potentially leading to discomfort or infection.
  • Hematoma - A localized collection of blood outside of blood vessels, which can occur in the submandibular space due to trauma or other causes, necessitating drainage to relieve pressure and prevent complications.

2. Procedure

The procedure for CPT® Code 41008 involves several critical steps to ensure effective drainage of the abscess, cyst, or hematoma in the submandibular space:

  • Step 1: Anesthesia - The procedure typically begins with the administration of local anesthesia to ensure patient comfort during the incision and drainage process.
  • Step 2: Incision - An incision is made intraorally, specifically over the area of the submandibular space where the abscess, cyst, or hematoma is located. This incision allows direct access to the affected tissue.
  • Step 3: Dissection - The underlying tissues are carefully dissected to expose the abscess, cyst, or hematoma. This step is crucial for ensuring that the entire pathological area is accessible for drainage.
  • Step 4: Drainage - Once the abscess, cyst, or hematoma is exposed, it is opened to allow the contents to drain. This may involve breaking up any compartments that have formed within the abscess or cyst to facilitate complete drainage.
  • Step 5: Removal of Clots - In cases of hematoma, any blood clots present are removed to ensure that the area is clear and to promote healing.
  • Step 6: Placement of Drains - If necessary, drains may be placed in the cavity to prevent re-accumulation of fluid and to promote ongoing drainage as the area heals.

3. Post-Procedure

After the completion of the procedure, patients may require specific post-operative care to ensure proper healing and to monitor for any complications. This may include instructions on oral hygiene, pain management, and signs of infection to watch for. Follow-up appointments may be necessary to assess the healing process and to remove any drains if they were placed. Patients should be advised to maintain a soft diet and to avoid any activities that could stress the surgical site during the initial recovery period.

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).
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
