0.000What This Code Means
Long-term complications or residual effects remaining after recovery from nerve damage caused by toxic exposure or poisoning.
Coding Tips
- •Link to the specific toxic substance exposure code when available
- •Document the time elapsed since toxic exposure and current functional limitations
Clinical Significance
Sequelae of toxic polyneuropathy captures the lasting neurological damage after recovery from toxic substance-induced nerve injury. Patients may experience permanent sensory loss, weakness, or neuropathic pain. This diagnosis reflects the chronic disease burden in patients who have survived toxic exposures, including chemotherapy survivors, and their ongoing functional and therapeutic needs.
Documentation Requirements
- ✓History of prior toxic polyneuropathy with identification of the causative toxin when known
- ✓Documentation that the acute toxic exposure phase has resolved
- ✓Current residual neurological deficits: weakness, numbness, pain
- ✓Functional limitations resulting from the residual nerve damage
- ✓Ongoing management for chronic sequelae symptoms
- ✓Provider's explicit statement linking current deficits to prior toxic polyneuropathy
Commonly Confused Codes
G62.0 — Drug-induced polyneuropathy is for the active condition during toxic drug exposureG62.2 — Polyneuropathy due to other toxic agents is for active toxic neuropathy, not sequelaeG65.0 — Sequelae of Guillain-Barre syndrome is for autoimmune etiology, not toxicG65.1 — Sequelae of other inflammatory polyneuropathy is for inflammatory etiology, not toxic
