What This Code Means

A bacterial or fungal infection occurring at an amputation site when the specific limb location is not documented or specified.

Coding Tips

•Use this code only when the specific extremity cannot be determined; otherwise use more specific codes T87.41-T87.44
•Document the causative organism and severity of infection for complete clinical picture

Clinical Significance

Infection of amputation stump represents a serious post-surgical complication requiring immediate antibiotic therapy and potential surgical intervention. This diagnosis indicates poor wound healing and increased risk of sepsis or need for revision amputation.

Documentation Requirements

✓Documentation of infection at amputation stump site
✓Clinical signs of infection (erythema, warmth, purulent drainage)
✓Laboratory evidence supporting infection (elevated WBC, cultures)
✓Specific organism identification when available
✓Antibiotic therapy prescribed or administered
✓Assessment of infection severity and extent
✓Treatment response documentation
✓Risk factors contributing to infection
