I/I react d/t cystostomy catheter, sequela

This code signifies a chronic or residual infectious or inflammatory complication directly resulting from a previously placed cystostomy catheter. It indicates that the patient is experiencing ongoing issues attributable to the body's long-term reaction to the catheter, even if the catheter is no longer present or the initial acute infection has resolved.

Use this code when documenting persistent infection, chronic inflammation, or other long-term sequelae that are a direct consequence of a cystostomy catheter. This applies to situations where the initial acute event has passed, but the patient continues to suffer from related conditions. Examples include chronic cystitis, granuloma formation, or recurrent infections linked to the catheter's historical presence.

• Requires a seventh character 'S' to indicate sequela, meaning the complication is a late effect.
• Do not use for acute or current infections directly related to a present catheter; those would typically fall under T83.510A or T83.510D.
• Always link to a definitive diagnosis of the specific sequela (e.g., chronic cystitis, fistula) if known, using an additional code.
