Opponensplasty is a surgical procedure aimed at restoring the ability to abduct the thumb in patients who have experienced damage to the median nerve. This condition often results in a loss of function and dexterity in the hand, particularly affecting the thumb's movement. The procedure involves various techniques, each designed to re-establish the thumb's position and functionality. Among the methods utilized are the transfer of tendons such as the palmaris longus, flexor digiti superficialis, extensor indicis, extensor digiti minimi, and flexor pollicis brevis, among others. The specific technique chosen for the opponensplasty can vary based on the individual patient's needs and the surgeon's preference. For instance, in CPT® Code 26490, the transfer of the superficialis tendon is employed, which necessitates the creation of a pulley system using slips from the flexor carpi ulnaris and extensor carpi ulnaris tendons. This method involves a detailed surgical approach, including incisions and tendon manipulation, to ensure proper alignment and function of the thumb post-surgery. Other techniques, such as those described in CPT® Codes 26492 and 26494, involve tendon grafting and the transfer of hypothenar muscles, respectively. However, CPT® Code 26496 specifically refers to opponensplasty performed using methods other than those previously mentioned, such as the transfer of the palmaris longus tendon. This procedure is characterized by the creation of a fascial tube that aids in the restoration of thumb abduction, highlighting the complexity and variability of surgical approaches in treating median nerve injuries.

The procedure of opponensplasty is indicated for patients who have suffered median nerve damage, resulting in impaired thumb abduction. This condition can lead to significant functional limitations in hand use, affecting daily activities and overall quality of life. The following specific indications may warrant the performance of this procedure:
The procedure for CPT® Code 26496, which involves opponensplasty using methods other than superficialis transfer, tendon graft, or hypothenar muscle transfer, follows a specific surgical technique. The steps are as follows:
After the completion of the opponensplasty procedure, patients can expect a recovery period that involves careful monitoring and rehabilitation. Post-operative care typically includes immobilization of the thumb in a splint to maintain its position and allow for healing. Patients may be advised to engage in physical therapy to regain strength and mobility in the thumb and hand. The duration of recovery can vary based on individual healing rates and adherence to rehabilitation protocols. Regular follow-up appointments are essential to assess the surgical site, adjust the splint as necessary, and monitor the overall progress of thumb function restoration.

| 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. | 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). | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | F1 | Left hand, second digit | F5 | Right hand, thumb | FA | Left hand, thumb | 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) | SG | Ambulatory surgical center (asc) facility service |
