Official Description

Correction, hallux valgus with bunionectomy, with sesamoidectomy when performed; with proximal metatarsal osteotomy, any method

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 28295 involves the surgical correction of hallux valgus, commonly known as a bunion, through a bunionectomy that includes a proximal metatarsal osteotomy. Hallux valgus is a deformity characterized by the lateral deviation of the big toe, which can lead to pain and discomfort, particularly when wearing shoes. The correction aims to realign the first metatarsal bone to restore normal anatomy and function. In this procedure, a proximal osteotomy is performed, which refers to the surgical cutting of the metatarsal bone closer to the midfoot, as opposed to a distal osteotomy that occurs further down the bone. The surgery may also involve the removal of the sesamoid bones if they are damaged or inflamed, which can contribute to the patient's symptoms. The surgical approach typically includes a medial incision made just above the bunion, allowing access to the metatarsophalangeal joint. This detailed procedure is essential for alleviating pain and improving the alignment of the toe, ultimately enhancing the patient's ability to walk and wear footwear comfortably.

1. Indications

The procedure described by CPT® Code 28295 is indicated for patients suffering from hallux valgus, particularly when accompanied by a bunion and associated symptoms. The following conditions may warrant this surgical intervention:

  • Hallux Valgus Deformity A significant lateral deviation of the big toe that causes pain and discomfort.
  • Bunion Formation The presence of a bony bump at the base of the big toe, which can lead to inflammation and irritation.
  • Sesamoiditis Inflammation or injury to the sesamoid bones located beneath the first metatarsal head, which may require excision if symptomatic.
  • Failed Conservative Treatments Patients who have not responded to non-surgical management options such as orthotics, padding, or anti-inflammatory medications.

2. Procedure

The surgical procedure for CPT® Code 28295 involves several critical steps to effectively correct the hallux valgus deformity:

  • Step 1: Incision A medial incision is made just proximal to the medial eminence of the first metatarsal, extending over the metatarsophalangeal joint. This incision allows access to the underlying structures.
  • Step 2: Dissection The soft tissues are carefully dissected to expose the joint capsule of the metatarsophalangeal joint. This step is crucial for accessing the area that requires correction.
  • Step 3: Joint Capsule Incision The metatarsophalangeal joint capsule is incised, which exposes the medial eminence. This exposure is necessary for the subsequent excision of the bony prominence.
  • Step 4: Excision of the Medial Eminence The medial eminence is excised in line with the metatarsal shaft, which helps to alleviate the deformity and associated symptoms.
  • Step 5: Bone Cuts and Osteotomy The bone cuts are outlined on the metatarsal bone, and a section of bone is excised. This osteotomy is performed proximally to realign the metatarsal head.
  • Step 6: Lateral Shift of Metatarsal Head The metatarsal head is shifted laterally by 3-5 mm. This is achieved using a skin hook or towel clamps on the proximal bone segment, allowing for proper alignment.
  • Step 7: Stabilization The osteotomy is stabilized with a single Kirschner wire, ensuring that the new alignment is maintained during the healing process.
  • Step 8: Sesamoidectomy (if necessary) If the sesamoid bones are fractured or inflamed, a skin incision is made over the sesamoid bone, and soft tissues are dissected to excise the bone.
  • Step 9: Closure The soft tissue and skin are closed in layers, ensuring proper healing and minimizing complications.

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. Post-operative care typically includes monitoring for signs of infection, ensuring proper wound healing, and possibly utilizing a surgical shoe or boot to protect the foot. Physical therapy may be recommended to restore mobility and strength in the affected foot. Follow-up appointments are essential to assess the healing process and the alignment of the metatarsal. Patients should be advised on activity modifications to prevent undue stress on the surgical site during the recovery phase.

This is a primary code that can be used with these additional add-on codes.

20705 Add-on Code MPFS Status: Active Code APC N Removal of drug-delivery device(s), intra-articular (List separately in addition to code for primary procedure)
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).
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.
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).
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).
