I/I react d/t cranial or spinal infusion catheter, sequela

This code describes a long-term complication arising from a past infection or inflammatory response related to a cranial or spinal infusion catheter. It indicates that the patient is currently experiencing a residual effect or condition directly attributable to that prior adverse event, even if the original infection or inflammation has resolved.

Use this code when documenting a patient presenting with a chronic condition, such as persistent neurological deficits, chronic pain, or structural changes, that are a direct consequence of a previously treated infection or inflammatory reaction involving a cranial or spinal infusion catheter. This applies when the acute phase of the infection/inflammation has passed, but its lasting impact is still present and requires ongoing management.

• Assign this code as a secondary diagnosis to specify the nature of the sequela.
• Ensure documentation clearly links the current condition to the past catheter-related infection or inflammation.
• Do not use for active infections or acute inflammatory reactions; those require codes from the T85.73- series without the "S" seventh character.
