Toxic effect of other specified metals

This code identifies adverse health effects resulting from exposure to and absorption of metals other than those specifically classified elsewhere (e.g., lead, mercury, arsenic). It encompasses systemic toxicity, organ damage, or other pathological responses caused by substances like cadmium, chromium, copper, zinc, or thallium.

Apply this code when documentation clearly indicates a patient's illness or injury is directly attributable to the toxic effects of a specified metal not covered by more specific ICD-9 codes. This typically involves acute or chronic poisoning confirmed by laboratory findings (e.g., elevated metal levels in blood, urine, or tissue) and a clear exposure history.

• Always sequence this code as a secondary diagnosis, following the primary diagnosis describing the specific manifestation of the toxic effect (e.g., nephropathy, neuropathy).
• Ensure the medical record specifies the particular metal involved; if unspecified, consider codes for unspecified toxic effects.
• Distinguish between toxic effects (poisoning) and adverse effects of therapeutic use, which are coded differently.
