Official Description

Ostectomy, complete excision; all metatarsal heads, with partial proximal phalangectomy, excluding first metatarsal (eg, Clayton type procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 28114 involves a surgical intervention known as ostectomy, specifically the complete excision of all metatarsal heads, excluding the first metatarsal. This procedure is typically indicated for patients experiencing bony overgrowth at the second, third, fourth, and fifth metatarsal heads, which can lead to pain and functional impairment. The surgical approach includes making longitudinal or lazy-S incisions over the dorsal aspects of the affected metatarsal heads, allowing for adequate access to the underlying structures. During the operation, care is taken to dissect the soft tissues while protecting the superficial blood vessels to minimize complications. The long extensor tendons are identified, and tenectomies may be performed as necessary to facilitate the excision of the metatarsal heads. The joint capsules are incised, and capsular flaps are created to expose the metatarsal heads fully. Following the excision, the bases of the proximal phalanges are also removed, and stabilization of the joints is achieved using Kirschner wires. Finally, any excess joint capsule tissue is either excised or plicated, and the overlying soft tissues are meticulously closed in layers to promote optimal healing.

1. Indications

The procedure described by CPT® Code 28114 is indicated for the treatment of bony overgrowth at the metatarsal heads, specifically the second, third, fourth, and fifth metatarsals. This condition may present with symptoms such as pain, swelling, and functional limitations in the foot, often necessitating surgical intervention to alleviate discomfort and restore mobility.

  • Bony Overgrowth The primary indication for this procedure is the presence of bony overgrowth at the metatarsal heads, which can lead to significant pain and functional impairment.
  • Metatarsalgia Patients may experience metatarsalgia, characterized by pain in the ball of the foot, often exacerbated by weight-bearing activities.
  • Deformities The procedure may also be indicated for deformities of the metatarsal heads that contribute to abnormal foot mechanics.

2. Procedure

The surgical procedure for CPT® Code 28114 involves several critical steps to ensure the complete excision of the metatarsal heads and associated structures.

  • Step 1: Incision The surgeon begins by making longitudinal or lazy-S incisions over the dorsal aspects of the second, third, fourth, and fifth metatarsal heads. This incision provides access to the underlying structures while minimizing trauma to surrounding tissues.
  • Step 2: Dissection Following the incision, the soft tissues are carefully dissected to expose the metatarsal heads. During this process, special attention is given to protecting the superficial blood vessels to prevent complications such as excessive bleeding.
  • Step 3: Identification of Tendons The long extensor tendons are identified during the dissection. If necessary, tenectomies are performed to facilitate the excision of the metatarsal heads, allowing for better access and visualization of the surgical site.
  • Step 4: Joint Capsule Incision The joint capsules surrounding the metatarsal heads are incised, and capsular flaps are created. This step is crucial for fully exposing the metatarsal heads for excision.
  • Step 5: Excision of Metatarsal Heads The metatarsal heads are then completely excised, along with the bases of the proximal phalanges. This excision addresses the bony overgrowth and alleviates the associated symptoms.
  • Step 6: Stabilization To stabilize the joints after excision, Kirschner wires are advanced through the proximal phalanges and into the metatarsal medullary canal. This stabilization is essential for proper healing and recovery.
  • Step 7: Joint Capsule Management Any redundancy in the joint capsules is either excised or plicated to ensure proper closure and function of the joint.
  • Step 8: Closure Finally, the overlying soft tissues are closed in layers, ensuring that the surgical site is properly sealed to promote healing and reduce the risk of infection.

3. Post-Procedure

After the completion of the procedure, patients can expect a recovery period that may involve pain management and limited weight-bearing activities to allow for proper healing. Post-operative care typically includes monitoring for signs of infection, managing any discomfort, and following up with physical therapy as needed to restore function. The surgical site should be kept clean and dry, and patients are advised to follow their surgeon's specific instructions regarding activity restrictions and wound care to ensure optimal recovery.

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).
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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
55 Postoperative management only: when 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 to the usual procedure number.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
