The procedure described by CPT® Code 28305 involves an osteotomy of the tarsal bones, specifically excluding the calcaneus or talus, and includes the use of an autograft. An osteotomy is a surgical procedure that involves cutting and reshaping bones to correct deformities or misalignments. In this case, the focus is on the navicular, cuboid, and cuneiform bones, which are critical components of the midfoot structure. This procedure is typically indicated for patients with congenital or acquired foot deformities, such as pes cavus, which is characterized by an excessively high arch. The term 'autograft' refers to the use of the patient's own bone tissue, which is harvested and then used to fill the defect created by the osteotomy. This approach is beneficial as it reduces the risk of rejection and complications associated with foreign graft materials. The surgical technique may involve an opening wedge osteotomy, where the bone is cut and spread apart to create a space that is then filled with the harvested bone graft. This method aims to restore proper alignment and function of the foot, ultimately improving the patient's mobility and quality of life.

The procedure described by CPT® Code 28305 is indicated for the treatment of various foot deformities, particularly those involving the tarsal bones. The following conditions may warrant this surgical intervention:
The procedure for CPT® Code 28305 involves several critical steps to ensure successful correction of the foot deformity:
After the procedure, patients are typically monitored for any complications and provided with post-operative care instructions. Recovery may involve limited weight-bearing on the affected foot, and the duration of immobilization in a cast can vary based on the individual case and the surgeon's recommendations. Follow-up appointments are essential to assess healing and ensure that the foot maintains proper alignment as it recovers. Physical therapy may also be recommended to aid in regaining strength and mobility in the foot.

| 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. | 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. | 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). | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | GC | This service has been performed in part by a resident under the direction of a teaching physician | 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) | T1 | Left foot, second digit | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
