Official Description

Graft; ear cartilage, autogenous, to nose or ear (includes obtaining graft)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 21235 involves the harvesting of autogenous ear cartilage for use in reconstructive surgery on the nose or ear. This type of graft utilizes the patient's own cartilage, specifically from the auricular or conchal regions of the ear, which minimizes the risk of rejection and complications associated with foreign graft materials. The process begins with making an incision either behind the ear (postauricular incision) or on the front of the ear, allowing access to the cartilage beneath the skin. Once the incision is made, the perichondrium, which is the connective tissue surrounding the cartilage, is carefully incised to expose the cartilage itself. The surgeon then excises a piece of cartilage, ensuring it is of adequate size and shape for the intended reconstructive purpose. After harvesting, the cartilage graft is meticulously shaped using a scalpel to fit the specific defect in the nose or ear. Finally, the graft is placed into the prepared site and secured in position with sutures, completing the procedure. This technique is essential for correcting deformities or reconstructing areas affected by trauma, congenital defects, or surgical excisions, thereby restoring both function and aesthetic appearance.

1. Indications

The procedure associated with CPT® Code 21235 is indicated for various reconstructive needs involving the nose or ear. The following conditions may warrant the use of an autogenous ear cartilage graft:

  • Reconstructive Surgery Repair of deformities or defects in the nose or ear due to trauma, congenital anomalies, or previous surgical interventions.
  • Cosmetic Enhancement Improvement of the aesthetic appearance of the ear or nose following injury or surgical correction.
  • Support for Structural Integrity Providing necessary support and shape to the nasal or auricular structures during reconstruction.

2. Procedure

The procedure for harvesting ear cartilage and utilizing it for reconstruction involves several critical steps:

  • Step 1: Incision An incision is made either behind the ear (postauricular incision) or on the anterior aspect of the ear. This approach allows for optimal access to the cartilage while minimizing visible scarring.
  • Step 2: Incising the Perichondrium The perichondrium, which is the fibrous tissue surrounding the cartilage, is carefully incised to expose the underlying cartilage. This step is crucial to ensure that the graft can be harvested without damaging the surrounding structures.
  • Step 3: Harvesting the Cartilage Graft A piece of cartilage is excised from the ear. The surgeon must ensure that the graft is of sufficient size and shape to meet the requirements of the reconstructive procedure.
  • Step 4: Shaping the Graft The harvested cartilage graft is then shaped with a scalpel to fit the specific defect in the nose or ear. This customization is essential for achieving a natural appearance post-reconstruction.
  • Step 5: Placement and Securing the Graft The shaped graft is placed into the defect in the ear or nose and secured with sutures. Proper fixation is necessary to ensure stability and integration of the graft into the surrounding tissue.

3. Post-Procedure

After the procedure, patients may require specific post-operative care to ensure proper healing and minimize complications. This may include instructions on wound care, managing discomfort, and recognizing signs of infection. Follow-up appointments are typically scheduled to monitor the healing process and assess the integration of the graft. Patients should be advised to avoid activities that may stress the surgical site, such as heavy lifting or vigorous exercise, during the initial recovery period. Additionally, any sutures used may need to be removed at a follow-up visit, depending on the type of sutures employed. Overall, careful adherence to post-procedure guidelines is essential for optimal recovery and successful outcomes.

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).
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.
GC This service has been performed in part by a resident under the direction of a teaching physician
SG Ambulatory surgical center (asc) facility service
LT Left side (used to identify procedures performed on the left side of the body)
RT Right side (used to identify procedures performed on the right side of the body)
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.)
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.
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
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).
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
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.)
