Official Description

Repair of dural/cerebrospinal fluid leak, not requiring laminectomy

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 63707 involves the repair of a dural or cerebrospinal fluid (CSF) leak that does not require a laminectomy. A CSF leak typically occurs when there is a tear or laceration in the spinal meninges, which are the protective membranes surrounding the spinal cord. This condition can arise from various causes, including trauma or complications from previous surgical procedures on the spine. When the meninges are compromised, it can lead to the formation of a cutaneous fistula, where the fluid leaks out through the skin, or it may seep into surrounding soft tissues without creating an external opening. In some instances, a fibrous capsule may develop in the soft tissue surrounding the leak. If the dura mater is torn but the arachnoid layer remains intact, it can lead to a condition known as pseudomeningocele, where the arachnoid herniates through the dural tear. The procedure coded as 63707 specifically addresses the repair of these leaks without the need for laminectomy, which is a surgical procedure that involves the removal of a portion of the vertebra to access the spinal cord. The repair process typically follows a diagnostic imaging procedure to accurately locate the leak, after which an incision is made over the affected area of the spine to facilitate the repair using nonabsorbable sutures and possibly fibrin sealant to ensure a watertight closure.

1. Indications

The procedure coded as CPT® 63707 is indicated for the repair of a dural or cerebrospinal fluid leak that does not necessitate a laminectomy. The following conditions may warrant this procedure:

  • Cerebrospinal Fluid Leak: A condition characterized by the leakage of CSF due to a tear or laceration in the spinal meninges, which may occur as a result of trauma or surgical complications.
  • Cutaneous Fistula Formation: The presence of an abnormal connection between the CSF and the skin, resulting from a persistent leak that has not healed properly.
  • Pseudomeningocele: A condition where the arachnoid layer herniates through a dural tear, leading to the accumulation of CSF in a fibrous sac.

2. Procedure

The procedure for CPT® Code 63707 involves several critical steps to effectively repair the CSF leak:

  • Step 1: Imaging Procedure Before the surgical repair, a separate imaging procedure is performed to accurately locate the site of the CSF leak. This imaging is essential for guiding the surgical intervention.
  • Step 2: Incision Once the leak is located, the surgeon makes an incision in the skin over the affected segment of the spine. This incision allows direct access to the area where the leak has occurred.
  • Step 3: Identification of the Leak The surgeon carefully identifies the specific area of the leak within the spinal meninges. This step is crucial for ensuring that the repair is targeted and effective.
  • Step 4: Closure of the Leak The repair of the leak is performed using nonabsorbable sutures to achieve primary closure of the dural defect. This method ensures that the CSF is contained within the spinal canal.
  • Step 5: Reinforcement To enhance the integrity of the closure and obtain a watertight seal, a fibrin sealant may be applied over the sutured area. This additional step helps to prevent any further leakage of CSF.

3. Post-Procedure

After the completion of the repair procedure, patients are typically monitored for any signs of complications, such as persistent CSF leakage or infection. Recovery may involve a period of rest and limited physical activity to allow the surgical site to heal properly. Follow-up appointments are essential to assess the success of the repair and to ensure that the CSF leak has been adequately addressed. Patients may also receive instructions regarding wound care and signs to watch for that could indicate complications.

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.)
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.
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.
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.
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.
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.
