Official Description

Capsulotomy; metatarsophalangeal joint, with or without tenorrhaphy, each joint (separate procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 28270 refers to a surgical procedure known as capsulotomy of the metatarsophalangeal joint. This procedure is typically indicated for the release of a joint contracture, which is a condition where the joint becomes stiff and cannot move freely due to the tightening of surrounding soft tissues. During the capsulotomy, a surgical incision is made directly over the affected metatarsophalangeal joint, which is the joint located at the base of the toes. The surgeon then carefully dissects the soft tissues to expose the joint capsule, allowing access to the fibrous tissue that may be causing the contracture. The fibrous tissue is meticulously dissected to release the contracture, thereby restoring normal movement to the joint. It is important to note that this procedure can be performed with or without tenorrhaphy, which is the surgical repair of one or more tendons associated with the joint. For procedures involving the interphalangeal joint, a different code, CPT® 28272, should be used. This distinction is crucial for accurate medical coding and billing.

1. Indications

The procedure described by CPT® Code 28270 is indicated for the following conditions:

  • Joint Contracture The primary indication for performing a capsulotomy of the metatarsophalangeal joint is to release a joint contracture, which restricts the normal range of motion.

2. Procedure

The capsulotomy procedure involves several key steps to ensure effective release of the joint contracture:

  • Step 1: Incision The surgeon begins by making a precise incision over the affected metatarsophalangeal joint. This incision is strategically placed to provide optimal access to the joint while minimizing damage to surrounding tissues.
  • Step 2: Dissection of Soft Tissues Following the incision, the surgeon carefully dissects the soft tissues surrounding the joint. This step is crucial as it allows for the exposure of the joint capsule, which is the fibrous tissue that encases the joint.
  • Step 3: Exposure of the Joint Capsule Once the soft tissues are adequately dissected, the joint capsule is exposed. This exposure is necessary for the subsequent steps of the procedure, as it provides direct access to the fibrous tissue that may be contributing to the contracture.
  • Step 4: Dissection of Fibrous Tissue The surgeon then meticulously dissects the fibrous tissue that is causing the contracture. This step is critical for releasing the tension within the joint, thereby restoring its normal function.
  • Step 5: Tenorrhaphy (if applicable) If indicated, the procedure may include tenorrhaphy, which involves the surgical repair of one or more tendons associated with the joint. This step is performed to ensure the integrity and functionality of the tendons after the release of the contracture.

3. Post-Procedure

After the capsulotomy procedure is completed, the patient may require specific post-operative care to ensure proper healing and recovery. This may include immobilization of the foot to prevent movement at the joint, pain management, and physical therapy to restore range of motion and strength. The surgeon will provide detailed instructions regarding activity restrictions and follow-up appointments to monitor the healing process. It is essential for patients to adhere to these guidelines to achieve optimal outcomes following the procedure.

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.
RT Right side (used to identify procedures performed on the right side of the body)
LT Left side (used to identify procedures performed on the left 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).

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).
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.
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.)
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).
99 Multiple modifiers: under certain circumstances 2 or more modifiers may be necessary to completely delineate a service. in such situations modifier 99 should be added to the basic procedure, and other applicable modifiers may be listed as part of the description of the service.
