Decompression fasciotomy is a surgical procedure aimed at alleviating the pressure within muscle compartments in the leg, specifically addressing the condition known as compartment syndrome. This syndrome occurs when swelling within a muscle compartment leads to increased pressure, which can compress blood vessels and nerves, potentially resulting in irreversible damage to the muscles and nerves if not treated promptly. The muscle compartments in the lower leg are encased in a tough, fibrous tissue called fascia, which does not stretch. When swelling occurs, the confined space of the compartment can restrict blood flow, leading to pain, muscle weakness, and sensory deficits. The procedure involves making incisions to access the affected compartments, which include the anterior, lateral, deep posterior, and superficial posterior compartments. In the case of CPT® Code 27894, both the anterior and/or lateral compartments, as well as the posterior compartments, are decompressed. This is achieved through two incisions, allowing for thorough inspection and debridement of any nonviable muscle or nerve tissue. The incisions are left open and covered with a dressing to facilitate healing, and the patient is typically returned to the operating room for closure once the swelling has decreased, usually within a timeframe of 24 to 72 hours.

Decompression fasciotomy is indicated for the treatment of compartment syndrome, which can arise from various conditions that lead to increased pressure within the muscle compartments of the leg. The following are specific indications for performing this procedure:
The procedure for decompression fasciotomy involves several critical steps to ensure effective treatment of compartment syndrome. The following outlines the procedural steps associated with CPT® Code 27894:
After the decompression fasciotomy, the patient is monitored closely for signs of improvement in symptoms and to ensure that swelling is subsiding. The open incisions are typically covered with dressings, and the patient may require follow-up visits to assess healing. Once the swelling has sufficiently decreased, usually within 24 to 72 hours, the patient is returned to the operating room for closure of the incisions. Post-operative care may include pain management, physical therapy, and monitoring for any complications such as infection or delayed healing. The overall goal of the procedure is to restore normal function and prevent long-term damage to the muscles and nerves.

| 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). | 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. | 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. | 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). | 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 | GW | Service not related to the hospice patient's terminal condition | 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) | XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | 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 |
