Biopsy of salivary gland; needle

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 42400 refers to a biopsy of the salivary gland using a needle. This type of biopsy is a minimally invasive technique employed to obtain tissue samples from the salivary gland for diagnostic purposes. The primary reasons for performing this biopsy include investigating the cause of gland enlargement, evaluating any lumps or masses present on the gland, and diagnosing conditions such as Sjogren's disease. Sjogren's disease is an autoimmune disorder that leads to a reduction in tear production, resulting in dry eyes, as well as decreased saliva production, causing dry mouth and dry mucous membranes. During the procedure, a core needle biopsy is conducted, which involves disinfecting the skin over the biopsy site and administering a local anesthetic to minimize discomfort. A small incision is made in the skin to facilitate the insertion of the needle into the salivary gland, allowing for the collection of a tissue sample. If a lump or mass is identified, imaging guidance may be utilized to accurately direct the needle to the appropriate location. The collected tissue sample is then prepared for histological evaluation, which is reported separately to assess the cellular characteristics of the tissue and aid in diagnosis.

1. Indications

The biopsy of the salivary gland using a needle, as described by CPT® Code 42400, is indicated for several specific clinical scenarios. These include:

  • Enlargement of the Gland - The procedure is performed to investigate the underlying cause of swelling in the salivary gland.
  • Lump or Mass Evaluation - It is utilized to assess any lumps or masses that may be present on the salivary gland, which could indicate various pathological conditions.
  • Diagnosis of Sjogren's Disease - The biopsy aids in diagnosing Sjogren's disease, an autoimmune disorder characterized by symptoms such as dry mouth and dry eyes due to reduced glandular secretions.

2. Procedure

The procedure for a needle biopsy of the salivary gland involves several critical steps to ensure accurate tissue sampling. First, the skin over the biopsy site is thoroughly disinfected to minimize the risk of infection. Following disinfection, a local anesthetic is injected to numb the area, ensuring patient comfort during the procedure. A small incision is then made in the skin to provide access to the salivary gland. A core needle is inserted into the gland, and a tissue sample is carefully obtained. This technique allows for the collection of a sufficient amount of tissue for diagnostic evaluation. If a lump or mass is present, imaging guidance may be employed to assist in accurately directing the needle to the desired location within the gland. Once the tissue sample is collected, it is prepared for histological evaluation, which is reported separately to provide detailed information about the cellular composition of the sample.

3. Post-Procedure

After the needle biopsy of the salivary gland, patients may experience some discomfort or swelling at the biopsy site, which is typically manageable with over-the-counter pain relief. It is important for patients to follow any post-procedure care instructions provided by their healthcare provider, which may include keeping the biopsy site clean and dry. Patients should also be advised to monitor for any signs of infection, such as increased redness, swelling, or discharge from the incision site. 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.

X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician
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
X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period
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.
