Leakage of cranial or spinal infusion catheter, sequela

This code signifies a long-term complication arising from a previous leakage of a cranial or spinal infusion catheter. It indicates that the patient is experiencing residual effects or conditions directly attributable to that past leakage event, rather than an active, ongoing leak. These sequelae could include chronic pain, neurological deficits, or other persistent issues.

Apply this code when documenting a patient's current condition that is a direct consequence of a previously resolved or treated leakage of a cranial or spinal infusion catheter. This is appropriate for follow-up encounters where the original leakage is no longer active but its lasting impact is being addressed. Do not use for acute or active leakage events.

• Requires a seventh character "S" to indicate sequela, signifying the late effects of the initial leakage.
• Always sequence this code after the code(s) for the specific manifestation(s) of the sequela (e.g., chronic headache, neurological deficit).
• Ensure documentation clearly links the current condition to the past catheter leakage.
