Official Description

Decompression; unspecified nerve(s) (specify)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Decompression is a surgical procedure aimed at alleviating pressure on a nerve that may be experiencing entrapment. This entrapment can occur due to various factors, including inflammation of the surrounding tissues, the presence of a tumor or mass, or the formation of scar tissue and adhesions. During the procedure, an incision is made in the skin over the affected nerve, allowing access to the underlying soft tissues. The surgeon carefully dissects these tissues to identify the nerve and any surrounding scar tissue or adhesions that may be compressing it. To relieve the pressure on the nerve, additional structures such as fascia or ligaments may also be divided. Once the nerve is completely freed from any impinging structures and surrounding tissue, the soft tissues are meticulously closed in layers to promote healing. The CPT® Code 64722 is utilized for the decompression of any unspecified nerve that does not have a more specific code available.

1. Indications

The procedure of nerve decompression is indicated for various conditions that lead to nerve entrapment. These indications may include:

  • Nerve Entrapment Syndromes Conditions where nerves are compressed due to surrounding structures, leading to pain, numbness, or weakness.
  • Inflammation Inflammatory processes that can cause swelling and pressure on the nerve.
  • Presence of Tumors or Masses Tumors or abnormal growths that may exert pressure on nearby nerves.
  • Scar Tissue Formation Adhesions or scar tissue that develop post-surgery or due to injury, which can entrap nerves.

2. Procedure

The procedure for nerve decompression involves several critical steps to ensure the successful release of the affected nerve. These steps include:

  • Step 1: Incision The surgeon begins by making an incision in the skin over the area where the nerve is located. This incision allows for direct access to the underlying tissues and the nerve itself.
  • Step 2: Dissection of Soft Tissues Following the incision, the surgeon carefully dissects the soft tissues surrounding the nerve. This dissection is performed with precision to avoid damaging the nerve and to expose it adequately.
  • Step 3: Identification of the Nerve Once the soft tissues are dissected, the surgeon identifies the nerve that is entrapped. This step is crucial for ensuring that the correct nerve is treated during the procedure.
  • Step 4: Release of Scar Tissue and Adhesions The surgeon then proceeds to dissect any scar tissue or adhesions that are found to be compressing the nerve. This step is essential for relieving the pressure on the nerve and restoring its function.
  • Step 5: Division of Additional Structures In some cases, additional structures such as fascia or ligaments may need to be divided to further relieve pressure on the nerve. This step is performed as necessary based on the specific anatomy and condition of the patient.
  • Step 6: Closure of Soft Tissues After the nerve has been completely freed from surrounding tissue and any impinging structures, the surgeon closes the soft tissues in layers. This layered closure is important for promoting proper healing and minimizing complications.

3. Post-Procedure

Post-procedure care following nerve decompression is essential for optimal recovery. Patients are typically monitored for any immediate complications and may be advised on pain management strategies. Rehabilitation may be recommended to restore function and strength in the affected area. Follow-up appointments are crucial to assess healing and ensure that the nerve is recovering properly. Patients should be informed about signs of complications, such as increased pain, swelling, or changes in sensation, and instructed to report these to their healthcare provider promptly.

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.
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).
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.
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.
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
RT Right side (used to identify procedures performed on the right side of the body)
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).
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.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 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).
