0.000What This Code Means
An infection develops at or around the cystostomy site, the surgically created opening in the bladder used for urine drainage. This can involve the stoma itself or surrounding tissue.
Coding Tips
- •Document the organism identified if culture results are available
- •Confirm active infection is present; do not code for prophylactic antibiotic use alone
Clinical Significance
Cystostomy infection represents a significant complication that can lead to urosepsis and systemic complications, requiring aggressive antibiotic therapy and possible device revision. This complication substantially increases care complexity and morbidity risk in patients requiring urinary diversion.
Documentation Requirements
- ✓Clinical evidence of infection at cystostomy site
- ✓Microbiological culture results and organism identification
- ✓Documentation of cystostomy procedure and timeline
- ✓Assessment of local vs systemic infection signs
- ✓Antibiotic therapy selection and duration
- ✓Response to treatment and resolution documentation
- ✓Complications such as sepsis or device removal requirements
- ✓Preventive measures and care plan modifications
