Official Description

Biopsy, soft tissue of neck or thorax

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Soft tissue biopsy of the neck or thorax involves the extraction of a sample from the soft tissues located in these regions. Soft tissues encompass a variety of structures, including muscles, tendons, fat, blood vessels, lymph vessels, nerves, and the tissues that surround joints. The procedure is typically performed under local, regional, or general anesthesia, or with conscious sedation, depending on the specific site and depth of the biopsy being conducted. Prior to the biopsy, the area over the intended site is thoroughly cleansed to minimize the risk of infection. A surgical incision is then made, allowing the physician to carefully dissect the tissue down to the mass or lesion of interest, while taking precautions to protect any nearby blood vessels and nerves. Once the tissue sample is obtained, it is sent to a laboratory for histological evaluation, which is reported separately. Finally, the incision is closed using sutures to promote proper healing.

1. Indications

Soft tissue biopsy of the neck or thorax is indicated for various clinical scenarios where tissue sampling is necessary to diagnose or evaluate a condition. The following are specific indications for performing this procedure:

  • Suspicious Mass or Lesion A biopsy may be performed when a mass or lesion is detected in the soft tissues of the neck or thorax that requires further investigation to determine its nature.
  • Unexplained Symptoms Patients presenting with unexplained symptoms such as swelling, pain, or other abnormalities in the neck or thoracic region may require a biopsy to identify underlying pathologies.
  • Monitoring Known Conditions In cases where a patient has a known condition affecting the soft tissues, a biopsy may be necessary to monitor changes or progression of the disease.

2. Procedure

The procedure for a soft tissue biopsy of the neck or thorax involves several critical steps to ensure the safe and effective collection of tissue samples. The following outlines the procedural steps:

  • Preparation The patient is positioned appropriately, and the area over the planned biopsy site is cleansed thoroughly to reduce the risk of infection. Anesthesia is administered based on the depth and location of the biopsy, which may include local, regional, or general anesthesia, or conscious sedation.
  • Incision Once the anesthesia has taken effect, a surgical incision is made over the biopsy site. The incision is carefully planned to provide adequate access to the tissue while minimizing trauma to surrounding structures.
  • Tissue Dissection The surgeon dissects the tissue down to the mass or lesion, taking great care to avoid damaging any nearby blood vessels and nerves. This step is crucial to ensure that the sample is obtained without causing unnecessary complications.
  • Tissue Sample Collection A sample of the tissue is then obtained from the mass or lesion. This sample is critical for histological evaluation and must be handled carefully to preserve its integrity.
  • Closure After the tissue sample has been collected, the incision is closed using sutures. Proper closure is essential for promoting healing and minimizing scarring.

3. Post-Procedure

After the soft tissue biopsy of the neck or thorax, patients may experience some discomfort or swelling at the biopsy site. It is important to monitor the area for any signs of infection, such as increased redness, warmth, or discharge. Patients are typically advised on how to care for the incision site, including keeping it clean and dry. Follow-up appointments may be scheduled to discuss the results of the histological evaluation and to determine any further necessary actions based on the findings. Recovery time may vary depending on the individual and the extent of the procedure, but most patients can resume normal activities within a few days, barring any complications.

77002 CPT Add On MPFS Status: Active Code APC N ASC N1 Physician Quality Reporting CPT Assistant Article Fluoroscopic guidance for needle placement (eg, biopsy, aspiration, injection, localization device) (List separately in addition to code for primary procedure)
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).
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).
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.)
