Official Description

Excision, intra and extracranial, benign tumor of cranial bone (eg, fibrous dysplasia); without optic nerve decompression

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 61563 involves the surgical excision of a benign tumor located in the cranial bone, which may include conditions such as fibrous dysplasia. This operation is performed both intra- and extracranially, meaning that the surgeon accesses the tumor from both inside the skull and from the outside, depending on the tumor's location and size. The primary goal of this procedure is to remove the tumor while preserving surrounding structures and minimizing damage to the cranial bone. It is important to note that this specific code is used when the excision does not involve decompression of the optic nerve. If optic nerve decompression is required during the procedure, CPT® Code 61564 should be utilized instead. This distinction is crucial for accurate coding and billing, as it reflects the complexity and extent of the surgical intervention performed.

1. Indications

The procedure associated with CPT® Code 61563 is indicated for the removal of benign tumors of the cranial bone. These tumors may present with various symptoms or conditions that necessitate surgical intervention. The following are explicitly provided indications for this procedure:

  • Benign Tumors The presence of benign tumors such as fibrous dysplasia that may cause discomfort, structural issues, or other complications.
  • Skull Deformities Conditions that lead to deformities in the skull structure, which may require correction through surgical excision.
  • Neurological Symptoms Symptoms that may arise from the tumor's presence, such as headaches or other neurological deficits, warranting surgical evaluation and intervention.

2. Procedure

The procedure for CPT® Code 61563 involves several critical steps to ensure the safe and effective removal of the benign tumor from the cranial bone. The following procedural steps are outlined:

  • Step 1: Preoperative Assessment Prior to the surgery, a thorough preoperative assessment is conducted, including imaging studies such as CT or MRI scans to determine the tumor's size, location, and relationship to surrounding structures. This assessment helps in planning the surgical approach.
  • Step 2: Anesthesia Administration The patient is then placed under general anesthesia to ensure comfort and immobility during the procedure. Anesthesia is crucial for minimizing pain and anxiety throughout the surgical process.
  • Step 3: Surgical Incision The surgeon makes an incision in the scalp, which may vary in length depending on the tumor's location. This incision allows access to the cranial bone and the underlying tumor.
  • Step 4: Bone Removal Once access is achieved, the surgeon carefully removes a section of the cranial bone to expose the tumor. This step requires precision to avoid damaging surrounding tissues and structures.
  • Step 5: Tumor Excision The benign tumor is then excised from the cranial bone. The surgeon ensures complete removal to prevent recurrence and to address any associated symptoms.
  • Step 6: Bone Reconstruction After the tumor is removed, the surgeon may reconstruct the cranial bone if necessary, using techniques that may involve repositioning the removed bone or using graft materials.
  • Step 7: Closure Finally, the incision is closed in layers, typically using sutures or staples, and a sterile dressing is applied to protect the surgical site during the initial healing phase.

3. Post-Procedure

Post-procedure care following the excision of a benign tumor of the cranial bone is essential for optimal recovery. Patients are typically monitored in a recovery area until they are stable. Common post-operative considerations include managing pain with prescribed medications, monitoring for any signs of infection at the surgical site, and ensuring proper wound care. Patients may also be advised to limit physical activity for a specified period to promote healing. Follow-up appointments are crucial to assess recovery progress and to address any complications that may arise. The expected recovery time can vary based on individual factors and the extent of the surgery performed.

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.
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).
