Persistent postprocedural fistula, subsequent encounter

This code signifies the continued presence of an abnormal connection between two organs, vessels, or an organ and the skin, that developed as a complication following a medical procedure. The fistula has not resolved and is still being actively managed or evaluated during this encounter.

Use this code for encounters where a patient is being seen for ongoing treatment, evaluation, or management of a postprocedural fistula that was previously diagnosed. This applies to follow-up visits after initial treatment, or for further diagnostic work-up of the persistent fistula.

• Requires a seventh character "D" for subsequent encounter, indicating ongoing care for the complication.
• Always sequence this code after the primary diagnosis for the underlying condition or reason for the original procedure, if applicable.
• Do not use for initial diagnosis of a postprocedural fistula; refer to the "A" seventh character for initial encounter.
