Official Description

Craniectomy or craniotomy; with treatment of penetrating wound of brain

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 61571 involves a craniectomy or craniotomy, which are surgical techniques used to access the brain. In this context, the physician performs the surgery specifically to address a penetrating wound of the brain. A craniectomy refers to the removal of a portion of the skull, while a craniotomy involves creating an opening in the skull without removing a section. The primary goal of this procedure is to treat injuries that penetrate the brain tissue, which can result from trauma, such as gunshot wounds or other severe impacts. By removing a section of the skull, the surgeon can directly access the affected area of the brain, allowing for necessary interventions to repair damage, control bleeding, or remove foreign objects. This procedure is critical in emergency situations where immediate action is required to prevent further neurological damage and to stabilize the patient’s condition.

1. Indications

The procedure associated with CPT® Code 61571 is indicated for specific conditions that necessitate surgical intervention to address penetrating wounds of the brain. These indications include:

  • Penetrating Trauma: This includes injuries caused by firearms, sharp objects, or other mechanisms that breach the skull and damage brain tissue.
  • Severe Head Injuries: Patients who have sustained significant head trauma that results in a penetrating wound may require this procedure to prevent further complications.
  • Intracranial Hemorrhage: The presence of bleeding within the brain due to a penetrating injury may necessitate surgical intervention to alleviate pressure and repair damaged vessels.

2. Procedure

The procedure for CPT® Code 61571 involves several critical steps to ensure effective treatment of the penetrating wound. These steps include:

  • Step 1: Patient Preparation The patient is positioned appropriately, and anesthesia is administered to ensure comfort and safety during the procedure. The surgical site is then cleaned and draped to maintain a sterile environment.
  • Step 2: Skull Access The surgeon makes an incision in the scalp to expose the underlying skull. Depending on the specific case, either a craniectomy or craniotomy is performed. In a craniectomy, a section of the skull is removed entirely, while in a craniotomy, an opening is created without removing the bone piece.
  • Step 3: Treatment of the Wound Once access to the brain is achieved, the surgeon carefully examines the wound. Any foreign objects, such as fragments from a bullet or debris, are removed. Additionally, any damaged brain tissue may be repaired or removed as necessary to promote healing and prevent infection.
  • Step 4: Closure After the treatment of the penetrating wound is complete, the surgeon closes the incision in the skull, either by replacing the removed bone flap in a craniotomy or by securing the area in a craniectomy. The scalp is then sutured or stapled closed to complete the procedure.

3. Post-Procedure

Following the procedure associated with CPT® Code 61571, patients typically require close monitoring in a recovery area or intensive care unit. Post-procedure care includes managing pain, monitoring for signs of infection, and assessing neurological function. Patients may also undergo imaging studies to evaluate the success of the intervention and to check for any complications. The expected recovery time can vary based on the extent of the injury and the specific interventions performed, but rehabilitation may be necessary to address any deficits resulting from the injury or surgery.

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).
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).
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.)
