Official Description

Partial excision (craterization, saucerization, or diaphysectomy) bone (eg, osteomyelitis); distal phalanx of finger

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 26236 involves a partial excision of bone, specifically targeting the distal phalanx of the finger to address osteomyelitis, which is an infection of the bone. This surgical intervention may also be referred to as craterization, saucerization, or diaphysectomy. Craterization and saucerization are techniques that focus on removing infected and necrotic bone tissue to create a shallow depression, or crater, in the bone surface. This depression facilitates drainage from the infected area, promoting healing and reducing the risk of further complications. Diaphysectomy, on the other hand, entails the removal of the infected segment of the shaft of a long bone. The procedure begins with an incision through the skin and soft tissue over the osteomyelitis site, allowing access to the affected area. The surgeon meticulously resects any soft tissue sinus tracts and devitalized tissue, exposing the necrotic and infected bone. The extent of bone removal is determined by the severity of the infection, and the procedure may involve creating drill holes in the bone and excavating the tissue between these holes to form an oval window. The ultimate goal of this procedure is to eliminate all devitalized and infected tissue, which is crucial for effective treatment and recovery.

1. Indications

The procedure described by CPT® Code 26236 is indicated for the treatment of osteomyelitis affecting the distal phalanx of the finger. Osteomyelitis is characterized by the infection of the bone, which can lead to necrosis and other complications if not addressed promptly. The following conditions may warrant this surgical intervention:

  • Osteomyelitis of the distal phalanx - This condition involves an infection localized to the distal phalanx of the finger, necessitating surgical intervention to remove infected bone tissue.
  • Necrotic bone tissue - The presence of necrotic bone, which is dead or dying tissue due to infection, requires excision to prevent further complications and promote healing.
  • Failure of conservative treatment - When non-surgical methods, such as antibiotics or other conservative measures, fail to resolve the infection, a partial excision may be necessary.

2. Procedure

The procedure for CPT® Code 26236 involves several critical steps to ensure the effective removal of infected bone tissue. The following outlines the procedural steps:

  • Step 1: Incision - The surgeon begins by making an incision in the skin over the site of osteomyelitis, carefully dissecting through the soft tissue to gain access to the affected area.
  • Step 2: Resection of Soft Tissue - Any soft tissue sinus tracts and devitalized soft tissue are resected to ensure that all infected material is removed, allowing for a clear view of the underlying bone.
  • Step 3: Exposure of Necrotic Bone - The area of necrotic and infected bone is exposed, providing the surgeon with access to the bone that requires treatment.
  • Step 4: Drilling and Excavation - A series of drill holes are made in the infected bone, and the bone between these holes is excavated using an osteotome to create an oval window. This step is crucial for removing the infected bone effectively.
  • Step 5: Removal of Devitalized Tissue - A curette may be employed to remove any remaining devitalized tissue from the medullary canal, ensuring that all infected material is eliminated.
  • Step 6: Irrigation - Once all devitalized and infected tissue has been removed, the surgical site is copiously irrigated with sterile saline or an antibiotic solution to cleanse the area and reduce the risk of infection.
  • Step 7: Closure - The surgical wound is then loosely closed, and a drain may be placed to facilitate any necessary drainage from the site post-operatively.

3. Post-Procedure

After the completion of the procedure, appropriate post-operative care is essential for recovery. The patient may be monitored for signs of infection or complications at the surgical site. Pain management strategies will be implemented to ensure patient comfort. The surgical site should be kept clean and dry, and any dressings should be changed as directed by the healthcare provider. Follow-up appointments will be necessary to assess healing and to remove any drains if placed. The patient may also require additional treatments, such as antibiotics, to prevent infection and promote healing of the affected area.
