Official Description

Partial excision (craterization, saucerization, or diaphysectomy) bone (eg, osteomyelitis); metacarpal

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 26230 involves a partial excision of bone, specifically targeting the metacarpal, to address osteomyelitis, which is an infection of the bone. This surgical intervention is also known by terms such as craterization, saucerization, or diaphysectomy. Craterization and saucerization refer to techniques that create a shallow depression in the bone surface by removing infected and necrotic bone, facilitating drainage from the infected area. Diaphysectomy, on the other hand, involves the removal of the infected segment of the shaft of a long bone. The procedure is performed through an incision in the skin, allowing access to the underlying soft tissues and the infected bone. The surgeon meticulously resects any soft tissue sinus tracts and devitalized soft tissue to expose the area of necrotic and infected bone. The extent of bone removal is determined by the severity of the infection, and the procedure aims to eliminate all infected tissue while preserving as much healthy bone as possible. This careful approach is crucial for promoting healing and preventing further complications associated with osteomyelitis.

1. Indications

The procedure described by CPT® Code 26230 is indicated for the treatment of osteomyelitis affecting the metacarpal bone. 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 Metacarpal - Infection of the metacarpal bone that requires surgical intervention to remove necrotic and infected tissue.

2. Procedure

The procedure for CPT® Code 26230 involves several critical steps to ensure the effective removal of infected bone tissue. The following outlines the procedural steps:

  • Step 1: Incision and Exposure - The surgeon begins by making an incision in the skin over the site of the osteomyelitis. This incision is carefully extended through the soft tissue layers to gain access to the infected area. The goal is to expose the necrotic and infected bone while preserving surrounding healthy tissue.
  • Step 2: Resection of Soft Tissue - Once the bone is exposed, any soft tissue sinus tracts and devitalized soft tissue are resected. This step is crucial to ensure that all infected tissue is removed, which helps to prevent the spread of infection and promotes healing.
  • Step 3: Bone Preparation - After the soft tissue has been addressed, the surgeon focuses on the infected bone. A series of drill holes are created in the necrotic and infected bone. The bone between these drill holes is then excavated using an osteotome to create an oval window. The extent of bone removal is determined by the severity of the infection, ensuring that all affected areas are adequately treated.
  • Step 4: Debridement - A curette may be utilized to remove any remaining devitalized tissue from the medullary canal. This thorough debridement continues until punctate bleeding is observed on the exposed bony surface, indicating that healthy bone has been reached.
  • Step 5: Irrigation and Closure - 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. The surgical wound is then loosely closed, and a drain may be placed to facilitate any necessary drainage post-operatively.

3. Post-Procedure

After the procedure, patients can expect a recovery period that may involve monitoring for signs of infection and ensuring proper wound healing. The surgical site will require care to maintain cleanliness and prevent complications. The presence of a drain may necessitate additional attention to manage any fluid output. Follow-up appointments will be essential to assess healing and determine if further interventions are needed. Pain management and rehabilitation may also be part of the post-procedure care plan, depending on the extent of the surgery and the patient's overall health status.

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.
