Official Description

Myringotomy including aspiration and/or eustachian tube inflation

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 69420 involves a myringotomy, which is a surgical intervention where a small incision is made in the tympanic membrane, commonly known as the eardrum. This procedure is performed to alleviate issues related to the Eustachian tube, a narrow passage that connects the middle ear to the back of the nose. The Eustachian tube plays a crucial role in equalizing air pressure in the middle ear and facilitating the drainage of mucus produced by the ear's lining. When this tube becomes blocked, it can lead to the trapping of air in the middle ear, resulting in negative pressure that can retract the tympanic membrane. Chronic blockage, often referred to as Eustachian tube dysfunction, can lead to fluid accumulation in the middle ear, which may cause hearing impairment. During the myringotomy, the physician not only makes the incision to relieve pressure but also performs aspiration to remove any fluid present in the middle ear. Additionally, the procedure may include inflation of the Eustachian tube with air to help restore its function. It is important to note that CPT® Code 69420 is specifically used when the procedure is performed without general anesthesia, while CPT® Code 69421 is designated for cases where general anesthesia is required.

1. Indications

The myringotomy procedure, as described by CPT® Code 69420, is indicated for several conditions related to Eustachian tube dysfunction and fluid accumulation in the middle ear. The following are the primary indications for performing this procedure:

  • Chronic Eustachian Tube Dysfunction - This condition occurs when the Eustachian tube fails to open properly, leading to persistent negative pressure and fluid buildup in the middle ear.
  • Middle Ear Effusion - The presence of fluid in the middle ear space, which can result from infections or allergies, may necessitate a myringotomy to relieve pressure and restore normal function.
  • Hearing Impairment - Fluid accumulation can cause conductive hearing loss, making it essential to perform a myringotomy to improve hearing by removing the fluid.
  • Recurrent Otitis Media - Patients with frequent ear infections may benefit from this procedure to prevent further episodes and complications associated with chronic infections.

2. Procedure

The myringotomy procedure involves several key steps that are performed to ensure effective treatment of the underlying issues. The following outlines the procedural steps:

  • Step 1: Anesthesia Administration - Before the procedure begins, local anesthesia may be administered to minimize discomfort. In cases where general anesthesia is required, the patient will be appropriately sedated to ensure a pain-free experience during the surgery.
  • Step 2: Incision Creation - The physician makes a small incision in the tympanic membrane (eardrum) using a specialized surgical instrument. This incision allows access to the middle ear space.
  • Step 3: Aspiration of Fluid - Once the incision is made, the physician uses suction to remove any fluid that has accumulated in the middle ear. This step is crucial for relieving pressure and restoring normal ear function.
  • Step 4: Eustachian Tube Inflation - After the fluid is removed, the physician may inflate the Eustachian tube with air. This inflation helps to open the tube, allowing for better drainage and equalization of pressure in the middle ear.
  • Step 5: Post-Procedure Care - Following the completion of the procedure, the physician will provide instructions for post-operative care, which may include monitoring for any signs of infection or complications.

3. Post-Procedure

After the myringotomy procedure, patients are typically monitored for a short period to ensure there are no immediate complications. Post-procedure care may include instructions to keep the ear dry and avoid water exposure for a specified duration. Patients may also be advised to watch for signs of infection, such as increased pain, fever, or discharge from the ear. Recovery time can vary, but many patients experience relief from symptoms shortly after the procedure. Follow-up appointments may be scheduled to assess the healing process and determine if further treatment is necessary.

50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. 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.
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).
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.)
