Arthrodesis of the midtarsal or tarsometatarsal joint, as described by CPT® Code 28740, refers to a surgical procedure aimed at fusing a single joint in the midfoot region. This procedure is typically indicated for patients suffering from severe, painful arthritis or those with congenital or acquired deformities affecting the midfoot. The goal of the surgery is to alleviate pain and restore function by permanently joining the bones of the affected joint, thereby eliminating movement that can cause discomfort. The surgical approach involves making a longitudinal incision over the targeted joint, ensuring that surrounding superficial nerves and blood vessels are carefully protected throughout the process. Once the joint is accessed, the surgeon meticulously removes all fibrous tissue and articular cartilage to prepare the bone surfaces for fusion. The articular surfaces are then shaped using an osteotome, and if necessary, a bone graft is harvested either locally or from donor sites such as the iliac crest or medial malleolus. The graft is tailored to fit the joint space and is secured in place with internal fixation devices, such as Steinmann pins, interfragmentary screws, or plates and screws, to maintain stability during the healing process. Finally, the incision is closed in layers, and a bulky dressing along with a splint is applied to support the foot during recovery.

The procedure of arthrodesis of the midtarsal or tarsometatarsal joint is indicated for the following conditions:
The arthrodesis procedure involves several critical steps to ensure successful fusion of the joint:
Post-procedure care following arthrodesis of the midtarsal or tarsometatarsal joint typically involves monitoring for signs of infection and ensuring proper healing of the surgical site. Patients are usually advised to keep the foot elevated and to limit weight-bearing activities for a specified period to promote optimal recovery. Follow-up appointments are essential to assess the healing process and to determine when physical therapy or rehabilitation can begin. The application of a bulky dressing and splint helps to immobilize the joint, which is critical for the success of the fusion. Patients may also receive instructions on pain management and activity restrictions to facilitate a smooth recovery.

| 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) | 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). | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | 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. | 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). | 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). | 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. | 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. | 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). | CG | Policy criteria applied | CR | Catastrophe/disaster related | FA | Left hand, thumb | GC | This service has been performed in part by a resident under the direction of a teaching physician | KX | Requirements specified in the medical policy have been met | PT | Colorectal cancer screening test; converted to diagnostic test or other procedure | SG | Ambulatory surgical center (asc) facility service | T1 | Left foot, second digit | T2 | Left foot, third digit | T3 | Left foot, fourth digit | T4 | Left foot, fifth digit | T5 | Right foot, great toe | T6 | Right foot, second digit | T7 | Right foot, third digit | T8 | Right foot, fourth digit | T9 | Right foot, fifth digit | TA | Left foot, great toe | X4 | Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period | 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 |
