Finding of abnormal level of heavy metals in blood

This code signifies the presence of an elevated or otherwise atypical concentration of heavy metals in a patient's bloodstream. It indicates a laboratory finding suggestive of heavy metal exposure or toxicity, without specifying the particular heavy metal involved. This finding often prompts further investigation into the source and clinical significance of the abnormal level.

Use this code when laboratory results confirm an abnormal level of an unspecified heavy metal in the blood. This is appropriate when the specific heavy metal (e.g., lead, mercury, arsenic) has not yet been identified or when the documentation broadly refers to "heavy metals" without further specificity. Documentation should clearly state an abnormal blood test result for heavy metals.

• Do not use this code if the specific heavy metal is identified; instead, use the more specific code for that particular heavy metal toxicity (e.g., T56.0X1A for lead poisoning).
• This code represents a finding, not a definitive diagnosis of poisoning or toxicity. Additional codes for symptoms or definitive diagnoses may be necessary.
• Sequence this code as a secondary diagnosis when a more specific condition or symptom related to the heavy metal exposure is the primary reason for the encounter.
