Official Description

Incision and drainage of thyroglossal duct cyst, infected

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 60000 refers to the incision and drainage of an infected thyroglossal duct cyst. The thyroglossal duct is a structure that is present during fetal development, facilitating the descent of the thyroid gland from the base of the tongue to its final anatomical position in the neck. Typically, this duct disappears after the thyroid gland has settled into place. However, in some individuals, remnants of the thyroglossal duct persist, resulting in the formation of cystic cavities in the neck. These cysts can accumulate fluid or mucus, leading to infection and subsequent swelling in the neck area. During the procedure, the physician palpates the enlarged area to identify the site of greatest fluctuance, which indicates the presence of fluid within the cyst. An incision is then made over this area to access the cyst cavity, allowing for drainage of the infected material. Blunt finger dissection may be employed to break up any loculations within the cyst, ensuring complete drainage. In some cases, the cyst cavity may be packed with gauze or a drain may be placed to facilitate further drainage. It is important to note that incision and drainage is not commonly performed due to the potential for scarring, which can complicate future infections. Instead, the preferred treatment options typically include antibiotic therapy and surgical excision of the cyst to prevent recurrence and complications.

1. Indications

The procedure of incision and drainage of a thyroglossal duct cyst is indicated in specific clinical scenarios where the cyst becomes infected. The following conditions warrant this procedure:

  • Infected Thyroglossal Duct Cyst The primary indication for this procedure is the presence of an infected thyroglossal duct cyst, which may present as a swollen, painful area in the neck.

2. Procedure

The procedure for incision and drainage of a thyroglossal duct cyst involves several critical steps to ensure effective treatment of the infection. The following procedural steps are outlined:

  • Step 1: Palpation of the Cyst The physician begins by palpating the enlarged area of the neck to identify the cyst. This examination helps determine the site of greatest fluctuance, which indicates the presence of fluid within the cyst.
  • Step 2: Incision Once the site is identified, the physician makes an incision in the skin over the area of greatest fluctuance. This incision allows access to the cyst cavity, facilitating drainage of the infected material.
  • Step 3: Drainage of the Cyst After the incision is made, the cyst cavity is opened, and the infected fluid or mucus is drained. This step is crucial for alleviating symptoms and preventing further complications.
  • Step 4: Blunt Finger Dissection To ensure complete drainage, blunt finger dissection is performed. This technique helps break up any loculations within the cyst, allowing for thorough evacuation of the contents.
  • Step 5: Packing or Drain Placement Following drainage, the cyst cavity may be packed with gauze to promote healing and prevent re-accumulation of fluid. Alternatively, a drain may be placed to facilitate ongoing drainage and reduce the risk of infection.

3. Post-Procedure

After the incision and drainage procedure, the patient may require specific post-procedure care to ensure proper healing and recovery. It is essential to monitor the incision site for signs of infection, such as increased redness, swelling, or discharge. Patients may be advised to keep the area clean and dry, and follow-up appointments may be scheduled to assess healing. In some cases, antibiotic therapy may be prescribed to address any underlying infection. It is important to note that due to the potential for scarring, which can complicate future infections, the procedure is not commonly performed, and alternative treatments such as antibiotic therapy and cyst excision may be recommended.

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