Official Description

Excision of bone (eg, for osteomyelitis or bone abscess); facial bone(s)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 21026 involves the excision of bone from the facial bones, which may include the maxilla or mandible, specifically targeting areas affected by conditions such as osteomyelitis or bone abscess. Osteomyelitis refers to an infection of the bone that can lead to the death of bone tissue, while a bone abscess is a localized collection of pus within the bone. During this surgical intervention, the physician utilizes specialized instruments such as drills, osteotomes, and saws to carefully remove the compromised bone tissue. This excision is critical in managing infections and preventing further complications. In some cases, antibiotic beads may be placed at the surgical site to aid in controlling the infection and promoting healing. It is important to note that any additional procedures, such as bone harvesting or grafting, should be reported separately. Following the excision, the incisions made during the procedure are meticulously closed to facilitate proper recovery and minimize the risk of postoperative complications.

1. Indications

The excision of bone from the facial bones, as described by CPT® Code 21026, is indicated for specific medical conditions that necessitate the removal of infected or necrotic bone tissue. The primary indications for this procedure include:

  • Osteomyelitis - A serious infection of the bone that can lead to the destruction of bone tissue, requiring surgical intervention to remove the infected area.
  • Bone Abscess - A localized infection within the bone that results in the formation of pus, necessitating excision to alleviate symptoms and prevent the spread of infection.

2. Procedure

The procedure for excising bone from the facial bones involves several critical steps to ensure effective removal of the affected tissue. The following procedural steps are typically performed:

  • Step 1: Anesthesia Administration - The patient is first prepared for surgery, which includes the administration of appropriate anesthesia to ensure comfort and pain management during the procedure.
  • Step 2: Incision - A surgical incision is made in the appropriate area of the facial bones to access the infected or necrotic bone. The location and size of the incision depend on the specific site of the infection.
  • Step 3: Bone Excision - Using specialized instruments such as drills, osteotomes, and saws, the surgeon carefully excises the dead or infected bone tissue. This step is crucial for removing all compromised areas to prevent further infection.
  • Step 4: Antibiotic Bead Placement - In some cases, antibiotic beads may be implanted at the surgical site to help control infection and promote healing. This adjunctive treatment is particularly beneficial in managing osteomyelitis.
  • Step 5: Closure of Incision - Once the excision is complete, the surgeon meticulously closes the incision using sutures or other closure techniques to ensure proper healing and minimize scarring.

3. Post-Procedure

After the excision of bone from the facial bones, the patient will require careful monitoring and post-operative care. Expected recovery may involve pain management, wound care, and follow-up appointments to assess healing. The physician may provide specific instructions regarding activity restrictions and signs of potential complications, such as increased swelling or signs of infection. It is essential for the patient to adhere to these guidelines to promote optimal recovery and prevent any adverse outcomes.

This is a primary code that can be used with these additional add-on codes.

20700 Add-on Code MPFS Status: Active Code APC N ASC N1 Manual preparation and insertion of drug-delivery device(s), deep (eg, subfascial) (List separately in addition to code for primary procedure)
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).
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.)
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.
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.
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)
GA Waiver of liability statement issued as required by payer policy, individual case
GC This service has been performed in part by a resident under the direction of a teaching physician
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
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.
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.
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.)
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).
99 Multiple modifiers: under certain circumstances 2 or more modifiers may be necessary to completely delineate a service. in such situations modifier 99 should be added to the basic procedure, and other applicable modifiers may be listed as part of the description of the service.
