Sequelae of other inflammatory polyneuropathy

This code describes the long-term or residual effects resulting from a past episode of an inflammatory polyneuropathy other than Guillain-Barré syndrome. These sequelae represent persistent neurological deficits or symptoms that continue after the acute phase of the original inflammatory condition has resolved.

Assign this code when a patient presents with chronic neurological impairments, such as persistent weakness, sensory loss, or neuropathic pain, that are directly attributable to a previously diagnosed inflammatory polyneuropathy. Documentation should clearly link the current symptoms to a past inflammatory polyneuropathy and indicate that these are not acute or ongoing manifestations of the original disease.

• Do not use this code for active or acute inflammatory polyneuropathy; instead, code the specific acute condition.
• Ensure documentation specifies "sequelae" or "residual effects" and identifies the prior inflammatory polyneuropathy.
• Sequence this code after the code for the specific manifestation of the sequelae, if applicable (e.g., muscle weakness, sensory disturbance).
