Official Description

Removal of foreign body, shoulder; subcutaneous

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 23330 involves the removal of a foreign body located in the subcutaneous tissue of the shoulder. The term "subcutaneous" refers to the layer of fat and connective tissue situated between the skin's dermis and the underlying muscle fascia. This procedure is typically indicated when a foreign object, which may have entered the body through trauma or other means, is present in this area. The physician utilizes palpation techniques or may employ radiographic imaging to accurately locate the foreign body prior to the surgical intervention. The removal process begins with the creation of a straight or elliptical incision in the skin, allowing access to the subcutaneous tissue. Once the incision is made, the physician carefully dissects through the tissue to identify the foreign body. Depending on the situation, the physician may use a hemostat or grasping forceps to extract the foreign object. In some cases, additional dissection may be necessary to fully free the foreign body from surrounding tissues. After successful removal, the wound is typically irrigated with normal saline or an antibiotic solution to reduce the risk of infection, and the incision is subsequently closed using sutures. This procedure is essential for preventing complications that may arise from retained foreign bodies, such as infection or inflammation.

1. Indications

The procedure associated with CPT® Code 23330 is indicated for the removal of a foreign body from the shoulder's subcutaneous tissue. The following conditions may warrant this procedure:

  • Presence of a foreign body in the subcutaneous tissue of the shoulder, which may result from trauma or injury.
  • Infection or inflammation caused by a retained foreign object, necessitating removal to prevent further complications.
  • Discomfort or pain experienced by the patient due to the foreign body, which may require surgical intervention for relief.

2. Procedure

The procedure for the removal of a foreign body from the shoulder's subcutaneous tissue involves several key steps:

  • Identification of the foreign body is the first step, where the physician may use palpation techniques or radiographs to locate the object accurately.
  • Incision creation follows, where a straight or elliptical incision is made in the skin over the identified foreign body to provide access to the subcutaneous tissue.
  • Tissue dissection is performed to carefully separate the subcutaneous tissue, allowing the physician to visualize and access the foreign body directly.
  • Foreign body removal is executed using a hemostat or grasping forceps to grasp and extract the foreign object from the tissue. In some cases, additional dissection may be necessary to free the foreign body completely.
  • Wound irrigation is conducted after the foreign body has been removed, typically using normal saline or an antibiotic solution to cleanse the area and minimize the risk of infection.
  • Closure of the incision is the final step, where the physician sutures the incision site to promote healing and protect the underlying tissues.

3. Post-Procedure

After the procedure, the patient may require specific post-operative care to ensure proper healing. This may include monitoring the incision site for signs of infection, such as increased redness, swelling, or discharge. Patients are often advised to keep the area clean and dry, and they may receive instructions on how to care for the sutures. Follow-up appointments may be necessary to assess healing and remove sutures if non-absorbable materials were used. Additionally, the physician may provide pain management recommendations and guidelines for activity restrictions to facilitate recovery.

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.
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.)
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
