Official Description

Drainage of abscess; parotid, simple

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 42300 refers to the drainage of a simple abscess located in the parotid gland, which is one of the major salivary glands situated in front of the ears. This condition, known as sialoadenitis, involves the accumulation of pus within the gland due to infection or blockage. The parotid glands are significant as they produce saliva, which aids in digestion and oral health. During the procedure, a surgical incision is made anterior to the ear and extends beneath the jawline, allowing access to the affected area. The surgeon raises skin flaps to expose the underlying fat and fascia, which are carefully dissected to reveal the parotid gland. Incisions are then made in the gland itself, parallel to the branches of the facial nerve, to facilitate the drainage of pus from the abscess cavity. Following drainage, the cavity is irrigated with sterile saline or an antibiotic solution to ensure cleanliness and reduce the risk of further infection. Depending on the extent of the abscess, drains may be placed to allow for continued drainage, and the incision is subsequently closed. It is important to note that for more complicated cases requiring extensive drainage, CPT® Code 42305 should be used instead.

1. Indications

The procedure for drainage of a parotid abscess is indicated in the following situations:

  • Salivary Gland Abscess: The primary indication for this procedure is the presence of an abscess within the parotid gland, which may result from infection or blockage of the salivary ducts.
  • Sialoadenitis: This condition, characterized by inflammation of the salivary glands, often leads to the formation of an abscess that requires surgical intervention for drainage.
  • Symptoms of Infection: Patients may present with symptoms such as swelling, pain, and tenderness in the area of the parotid gland, which necessitates drainage to alleviate discomfort and prevent further complications.

2. Procedure

The procedure for the drainage of a parotid abscess involves several critical steps to ensure effective treatment:

  • Step 1: The surgeon begins by making an incision anterior to the ear, which is strategically placed to provide optimal access to the parotid gland while minimizing damage to surrounding structures.
  • Step 2: The incision is then extended beneath the jawline, allowing the surgeon to raise skin flaps. This step is essential for exposing the underlying fat and fascia that cover the parotid gland.
  • Step 3: Once the fat and fascia are exposed, the surgeon carefully dissects these layers to reveal the parotid gland itself. This dissection must be performed with precision to avoid injury to the facial nerve branches that run in proximity to the gland.
  • Step 4: After exposing the gland, one or more incisions are made directly into the parotid gland, parallel to the branches of the facial nerve. This allows for effective drainage of the pus accumulated in the abscess cavity.
  • Step 5: Following the drainage of pus, the abscess cavity is irrigated with sterile saline or an antibiotic solution. This irrigation is crucial for cleaning the cavity and reducing the risk of postoperative infection.
  • Step 6: Depending on the extent of the abscess and the amount of drainage required, the surgeon may place drains within the cavity to facilitate ongoing drainage and prevent fluid accumulation.
  • Step 7: Finally, the incision is closed using appropriate suturing techniques to promote healing and minimize scarring.

3. Post-Procedure

After the drainage procedure, patients are typically monitored for any signs of complications, such as infection or excessive bleeding. Post-procedure care may include pain management, instructions for wound care, and follow-up appointments to assess healing. Patients may also be advised on dietary modifications to avoid irritation of the surgical site. The expected recovery time can vary based on the individual and the extent of the procedure, but most patients can anticipate a gradual return to normal activities as healing progresses. It is essential for patients to adhere to any prescribed follow-up care and report any unusual symptoms 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).
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.
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.)
