Burr hole(s) with evacuation and/or drainage of hematoma, extradural or subdural

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A burr hole craniotomy is a surgical procedure that involves creating one or more small openings, known as burr holes, in the skull to facilitate the evacuation and drainage of hematomas, which can be either extradural or subdural. This procedure is typically indicated when there is a collection of blood that needs to be removed to alleviate pressure on the brain. The process begins with an incision in the scalp, which is then flapped forward to provide access to the skull. A specialized surgical drill or perforator is used to create the burr hole, penetrating both the outer and inner tables of the skull. In cases of extradural hematomas, the blood collection is situated between the inner table of the skull and the dural membrane, while subdural hematomas involve blood accumulation between the dura mater and the arachnoid membranes. The procedure allows for the insertion of a cannula, which is equipped with a stylet, to access the hematoma site. Once the cannula is in place, a syringe is used to flush out the blood from the hematoma. After the evacuation of the hematoma, the dura is closed, and the defect in the skull is repaired, often using bone wax to ensure proper closure. It is important to note that this code does not apply to the aspiration of an intracerebral hematoma or cyst, which is a different procedure requiring a distinct approach and coding (CPT® Code 61156).

1. Indications

The burr hole procedure is indicated for the following conditions:

  • Extradural Hematoma - This condition occurs when there is a collection of blood between the inner table of the skull and the dural membrane, often resulting from trauma.
  • Subdural Hematoma - This involves the accumulation of blood between the dura mater and the arachnoid membranes, typically due to head injury or other causes of bleeding.

2. Procedure

The procedure consists of several critical steps to ensure effective drainage of the hematoma:

  • Step 1: Scalp Incision - The procedure begins with an incision made in the scalp, which is then flapped forward to expose the underlying skull. This step is essential for gaining access to the area where the burr hole will be created.
  • Step 2: Creation of Burr Hole - A surgical drill or perforator is utilized to create a burr hole through both the outer and inner tables of the skull. This opening allows for direct access to the hematoma site.
  • Step 3: Insertion of Cannula for Extradural Hematoma - For an extradural hematoma, a cannula with a stylet is inserted through a guide into the space between the inner table of the skull and the dural membrane. This step is crucial for accessing the blood collection.
  • Step 4: Evacuation of Blood - A syringe is attached to the cannula, and the collection of blood is flushed from the hematoma site. This process alleviates pressure on the brain and helps restore normal function.
  • Step 5: Insertion of Cannula for Subdural Hematoma - In cases of subdural hematoma, the dura is incised, and the blood collection between the dura and arachnoid membranes is located. A cannula with a stylet is again inserted to facilitate drainage.
  • Step 6: Final Evacuation and Closure - Similar to the extradural procedure, a syringe is used to flush out the blood from the subdural hematoma site. After the evacuation, the syringe is withdrawn, the dura is closed, and the skull defect is repaired using bone wax to ensure proper closure and stability.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any signs of complications, such as infection or re-accumulation of blood. Patients may require imaging studies to confirm the successful evacuation of the hematoma. Recovery time can vary based on the extent of the procedure and the patient's overall health. It is essential to follow up with the patient to assess neurological function and ensure proper healing of the surgical site.

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).
RT Right side (used to identify procedures performed on the right side of the body)
LT Left side (used to identify procedures performed on the left side of the body)
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
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).
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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
55 Postoperative management only: when 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 to the usual procedure number.
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.
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.
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).
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).
