Mech compl of cranial or spinal infusion catheter, sequela

This code signifies a long-term or residual issue stemming from a past mechanical problem with an infusion catheter placed in the cranium or spine. It indicates that the initial complication has resolved, but the patient continues to experience a lasting effect or condition directly attributable to that prior mechanical failure.

Apply this code when documenting a patient presenting with a sequela, such as chronic pain, neurological deficit, or persistent CSF leak, that is a direct consequence of a previously treated or resolved mechanical complication of a cranial or spinal infusion catheter. This is appropriate for follow-up encounters where the acute complication is no longer present but its lingering effects are being addressed.

• Always sequence this code after the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past mechanical complication of the catheter.
• Do not use this code for acute or ongoing mechanical complications; those require the appropriate acute T85.690A or T85.690D codes.
