Official Description

Drainage of lymph node abscess or lymphadenitis; simple

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 38300 involves the drainage of a lymph node abscess or lymphadenitis, which is a condition characterized by the inflammation of lymph nodes often due to infection. In this procedure, the healthcare provider first palpates the enlarged lymph node to identify the area that exhibits the greatest degree of fluctuance, indicating the presence of an abscess. Following this assessment, a local anesthetic is administered to ensure patient comfort during the procedure. The next step involves making an incision in the skin over the lymph node, followed by dissection of deeper tissues as necessary to adequately expose the site of the abscess. Once the lymph node is accessed, it is incised to allow for drainage of the accumulated pus or fluid. During this process, cultures may be collected and sent to a laboratory for further analysis to identify any infectious organisms present. After the drainage is complete, the incision may be managed in several ways: it can be packed open to facilitate continued drainage, a drain may be placed to prevent fluid accumulation, or the incision may be closed directly. It is important to note that this code is specifically used for simple procedures involving superficial lymph nodes, while CPT® Code 38305 is designated for more extensive procedures that require deeper tissue dissection, packing, drain placement, or secondary closure.

1. Indications

The procedure described by CPT® Code 38300 is indicated for the following conditions:

  • Lymph Node Abscess The presence of a localized collection of pus within a lymph node, often resulting from infection.
  • Lymphadenitis Inflammation of the lymph nodes, which may be due to various infectious agents, leading to swelling and discomfort.

2. Procedure

The procedure for drainage of a lymph node abscess or lymphadenitis involves several key steps:

  • Step 1: Palpation and Identification The healthcare provider begins by palpating the enlarged lymph node to assess its size and consistency. The area of greatest fluctuance is identified, which indicates the presence of an abscess that requires drainage.
  • Step 2: Anesthesia Administration Once the appropriate area is located, a local anesthetic is injected to numb the region, ensuring that the patient experiences minimal discomfort during the procedure.
  • Step 3: Incision and Dissection The skin over the lymph node is then incised, and deeper tissues may be dissected as necessary to adequately expose the abscess site. This step is crucial for accessing the fluid that needs to be drained.
  • Step 4: Drainage of the Abscess After the lymph node is adequately exposed, it is incised to allow for the drainage of the abscess. This step helps to relieve pressure and remove infected material from the lymph node.
  • Step 5: Culturing the Fluid During the drainage process, cultures may be obtained from the fluid and sent to the laboratory for identification of any infectious organisms. This is important for guiding appropriate antibiotic therapy.
  • Step 6: Wound Management Following the drainage, the incision site may be managed in several ways: it can be packed open to allow for continued drainage, a drain may be placed to prevent fluid accumulation, or the incision may be closed directly, depending on the specific circumstances of the case.

3. Post-Procedure

After the procedure, the patient may require monitoring for signs of infection or complications. Instructions for wound care will be provided, which may include keeping the area clean and dry, as well as any specific guidelines for changing dressings if applicable. The patient may also be advised on signs and symptoms to watch for that could indicate a need for further medical attention, such as increased redness, swelling, or discharge from the incision site. Follow-up appointments may be scheduled to assess healing and to review culture results, which can inform further treatment if necessary.

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.)
