Official Description

Incision and subcutaneous placement of cranial bone graft (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 61316 refers to the procedure of incision and subcutaneous placement of a cranial bone graft. This procedure is specifically performed when a cranial bone graft, which is typically removed during a craniectomy, is intended for future use in reconstructing a skull defect. The process involves creating a subcutaneous pocket, often referred to as subcutaneous banking, which is designed to preserve the viability of the bone graft. This is crucial as it allows the bone to remain suitable for autogenous grafting later on. The procedure begins with an incision made in the skin of the abdomen, where the subcutaneous pocket is fashioned. Once the pocket is created, the cranial bone flap, previously excised during the craniectomy, is carefully placed within this pocket. Finally, the skin and subcutaneous tissue are closed over the bone flap, ensuring that it is securely stored for potential future surgical use. This method not only aids in the preservation of the bone graft but also facilitates the planning of subsequent reconstructive procedures for the skull.

1. Indications

The procedure described by CPT® Code 61316 is indicated in specific clinical scenarios where a cranial bone graft is removed during a craniectomy and requires preservation for future use. The following conditions may warrant this procedure:

  • Cranial Defects - Patients with cranial defects resulting from trauma, tumors, or congenital anomalies may require a cranial bone graft for reconstruction.
  • Future Reconstruction Needs - When there is a planned future reconstructive surgery to address skull defects, preserving the cranial bone flap is essential.
  • Autogenous Grafting - The need for an autogenous bone graft, which utilizes the patient's own bone, is a key indication for this procedure, ensuring compatibility and reducing the risk of rejection.

2. Procedure

The procedure for CPT® Code 61316 involves several critical steps to ensure the successful placement of the cranial bone graft in a subcutaneous pocket. The following procedural steps are outlined:

  • Step 1: Incision - The procedure begins with the surgeon making an incision in the skin of the abdomen. This incision is strategically placed to allow for the creation of a subcutaneous pocket that will house the cranial bone graft.
  • Step 2: Formation of Subcutaneous Pocket - After the incision is made, the surgeon carefully dissects the subcutaneous tissue to create a pocket. This pocket is designed to securely hold the cranial bone flap, ensuring that it is protected and preserved for future use.
  • Step 3: Placement of Cranial Bone Flap - Once the subcutaneous pocket is formed, the cranial bone flap, which was removed during the craniectomy, is placed into this pocket. This step is crucial as it allows the bone to remain viable for later reconstruction.
  • Step 4: Closure - After the cranial bone flap is securely positioned within the subcutaneous pocket, the surgeon proceeds to close the incision. The skin and subcutaneous tissue are sutured together, ensuring that the bone flap is adequately covered and protected.

3. Post-Procedure

Post-procedure care for patients who have undergone the incision and subcutaneous placement of a cranial bone graft involves monitoring for any signs of complications, such as infection or improper healing of the incision site. Patients may be advised to follow specific wound care instructions to maintain the integrity of the surgical site. Additionally, the viability of the cranial bone flap should be assessed during follow-up visits, as it is intended for future use in reconstructive surgery. The timing and planning for the subsequent reconstructive procedure will depend on the patient's overall health and the specific clinical circumstances surrounding the initial craniectomy and graft placement.

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.
