Official Description

Removal of foreign body in muscle or tendon sheath; deep or complicated

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 20525 involves the surgical removal of a foreign body that has become lodged within a muscle or tendon sheath. This situation typically arises when an object, such as a splinter, metal fragment, or other debris, penetrates the skin and migrates into deeper tissues, causing discomfort, pain, or potential infection. The term "deep or complicated" indicates that the foreign body is not easily accessible and may require more extensive surgical intervention compared to a simple removal. The physician will make an incision above the affected area to access the foreign body, carefully dissecting through the cutaneous tissue to reach the site of the foreign object. If imaging studies, such as X-rays, are necessary to locate the foreign body prior to the procedure, these should be reported separately, as they are not included in the CPT® code for the removal itself. After the foreign body is successfully extracted, the surgical site will be evaluated for signs of infection. If no infection is present, the incision site will be closed. However, if there is evidence of infection, the site may be left open and packed with gauze to promote drainage and healing. This procedure is critical for alleviating symptoms and preventing further complications associated with retained foreign bodies in soft tissues.

1. Indications

The procedure associated with CPT® Code 20525 is indicated in cases where a foreign body is present within a muscle or tendon sheath, leading to symptoms such as pain, swelling, or infection. The following conditions may warrant this procedure:

  • Presence of a foreign body in the muscle or tendon sheath that requires surgical intervention for removal.
  • Symptoms of infection such as redness, warmth, and discharge at the site of the foreign body.
  • Persistent pain or discomfort that does not resolve with conservative treatment measures.

2. Procedure

The procedure for the removal of a foreign body from a muscle or tendon sheath involves several critical steps, which are detailed as follows:

  • Step 1: Preparation The patient is positioned appropriately, and the area surrounding the site of the foreign body is cleaned and sterilized to minimize the risk of infection. Local anesthesia may be administered to ensure the patient’s comfort during the procedure.
  • Step 2: Incision An incision is made above the affected area where the foreign body is located. The size and length of the incision depend on the depth and complexity of the foreign body’s location.
  • Step 3: Dissection The surgeon carefully dissects through the cutaneous tissue, layer by layer, to reach the muscle or tendon sheath. This step requires precision to avoid damaging surrounding structures.
  • Step 4: Removal of the Foreign Body Once the foreign body is located, it is gently extracted from the muscle or tendon sheath. If the foreign body is deeply embedded or complicated in its location, additional techniques may be employed to facilitate its removal.
  • Step 5: Site Evaluation After the foreign body is removed, the surgical site is evaluated for any signs of infection. This assessment is crucial in determining the next steps for closure.
  • Step 6: Closure If there is no infection present, the incision site is closed using sutures or staples. If infection is detected, the site may be packed open with gauze to allow for drainage and promote healing.

3. Post-Procedure

Post-procedure care for patients who have undergone the removal of a foreign body from a muscle or tendon sheath includes monitoring the surgical site for signs of infection, such as increased redness, swelling, or discharge. Patients may be advised to keep the area clean and dry, and to follow specific wound care instructions provided by the healthcare provider. Pain management may be necessary, and the physician may prescribe analgesics as needed. Follow-up appointments are typically scheduled to assess healing and to determine if further intervention is required, especially if the site was left open for drainage. Patients should be educated on the importance of reporting any unusual symptoms or complications that may arise during the recovery period.

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).
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
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).
