Official Description

Drainage of abscess of palate, uvula

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 42000 involves the drainage of an abscess located in the palate or uvula. The palate, which constitutes the roof of the mouth, is divided into two distinct parts: the hard palate, which is bony and forms the anterior section, and the soft palate, which is muscular and forms the posterior section. The uvula, a small conical structure that hangs from the soft palate, is made up of connective tissue, racemose glands, and some muscular fibers. During this procedure, a thorough examination of the roof of the mouth is conducted to locate the abscess pocket, which may be situated in either the soft palate or the uvula. Once identified, the abscess is treated by either puncturing it with a needle to aspirate the pus or by making an incision to allow the pus to drain freely. In the latter case, suction may be employed to remove the pus from the throat, and the incision is intentionally left open to facilitate ongoing drainage. This procedure is essential for alleviating pain and preventing further complications associated with the abscess.

1. Indications

The drainage of an abscess of the palate or uvula, as described by CPT® Code 42000, is indicated in the following situations:

  • Presence of an Abscess: The procedure is performed when there is a clinically significant abscess located in the soft palate or uvula that requires intervention to alleviate symptoms and prevent complications.
  • Symptoms of Infection: Patients may present with symptoms such as pain, swelling, or difficulty swallowing, which necessitate the drainage of the abscess to relieve discomfort and address the underlying infection.
  • Risk of Complications: The procedure is indicated when there is a risk of the abscess leading to further complications, such as airway obstruction or systemic infection, making timely drainage essential.

2. Procedure

The procedure for draining an abscess of the palate or uvula involves several key steps, which are outlined as follows:

  • Step 1: Examination of the Palate and Uvula The healthcare provider begins by conducting a thorough examination of the roof of the mouth, specifically focusing on the soft palate and uvula. This examination is crucial for identifying the location and extent of the abscess, which may present as a swollen, painful area.
  • Step 2: Puncturing the Abscess Once the abscess pocket is located, a needle is used to puncture the abscess. This step is performed with care to ensure that the pus within the abscess is aspirated effectively. The aspiration helps to relieve pressure and provides immediate symptom relief for the patient.
  • Step 3: Incision and Drainage Alternatively, if the abscess is large or not amenable to aspiration, an incision may be made to allow for drainage. The incision is made in the abscess pocket, and as the pus drains out, suction may be applied to remove the fluid from the throat. This method ensures that the abscess is adequately drained and reduces the risk of re-accumulation of pus.
  • Step 4: Leaving the Incision Open After the drainage is complete, the incision is intentionally left open. This allows for continued drainage of any residual pus and helps to prevent the formation of a new abscess. The open incision may require monitoring to ensure proper healing and to manage any potential complications.

3. Post-Procedure

Following the drainage of an abscess of the palate or uvula, patients may require specific post-procedure care. It is important to monitor the incision site for signs of infection or complications. Patients are typically advised to maintain good oral hygiene and may be prescribed pain management medications to alleviate discomfort. Additionally, follow-up appointments may be necessary to assess healing and ensure that the abscess does not recur. Patients should be educated on signs of complications, such as increased swelling, fever, or difficulty breathing, which would necessitate immediate medical attention.

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).
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.
