Official Description

Biopsy of floor of mouth

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure identified by CPT® Code 41108 refers to a biopsy of the floor of the mouth, which is a critical diagnostic intervention performed to assess abnormal growths, lesions, or areas that appear suspicious within the oral cavity. This procedure is essential for determining the nature of these abnormalities, which may include benign or malignant conditions. During the biopsy, a local anesthetic is administered to ensure patient comfort at the site where the biopsy will be performed. Following the administration of anesthesia, a precise incision is made in the floor of the mouth, allowing for the careful removal of a slice of tissue from the identified suspicious area. This tissue sample is crucial as it is subsequently sent for pathology examination, which is reported separately. The results of this examination provide vital information regarding the cellular composition of the tissue, aiding in the diagnosis and guiding further management of the patient's condition.

1. Indications

The biopsy of the floor of the mouth, as indicated by CPT® Code 41108, is performed under specific circumstances where there are concerns regarding abnormal growths or lesions. The following are the explicit indications for this procedure:

  • Abnormal Growths The presence of unusual masses or swellings in the floor of the mouth that require further evaluation to determine their nature.
  • Lesions Any lesions that appear atypical or suspicious, which may warrant investigation to rule out malignancy or other pathological conditions.
  • Suspicious Areas Areas of the floor of the mouth that exhibit changes in color, texture, or other characteristics that raise concern for potential disease processes.

2. Procedure

The procedure for a biopsy of the floor of the mouth involves several critical steps that ensure the accurate collection of tissue for diagnostic purposes. The following outlines the procedural steps involved:

  • Step 1: Anesthesia Administration The first step in the procedure is the administration of a local anesthetic at the planned biopsy site. This is crucial for minimizing discomfort and pain during the biopsy process, allowing the patient to remain comfortable throughout the procedure.
  • Step 2: Incision Once the local anesthetic has taken effect, the clinician makes a careful incision in the floor of the mouth. This incision is strategically placed to access the suspicious area while minimizing trauma to surrounding tissues.
  • Step 3: Tissue Removal After the incision is made, a slice of tissue is excised from the identified suspicious area. This step requires precision to ensure that an adequate sample is obtained for pathological examination, which is essential for accurate diagnosis.
  • Step 4: Sample Handling The excised tissue sample is then properly handled and prepared for transport to a pathology laboratory. It is important that the sample is sent for a separately reportable pathology examination to analyze the cellular structure and determine the presence of any disease.

3. Post-Procedure

After the biopsy of the floor of the mouth is completed, the patient may require specific post-procedure care to ensure proper healing and to monitor for any complications. Patients are typically advised to avoid certain activities, such as vigorous oral hygiene or consuming hot foods and beverages, to minimize irritation at the biopsy site. Additionally, the clinician may provide instructions regarding pain management, which may include over-the-counter analgesics. Follow-up appointments may be scheduled to discuss the pathology results and to assess the healing process. It is essential for patients to report any unusual symptoms, such as excessive bleeding or signs of infection, to their healthcare provider promptly.

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.
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).
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.)
