Toxic effect of chromium and its compounds, undet, sequela

This code signifies the long-term or residual effects resulting from a past exposure to chromium or its compounds, where the intent of the exposure (accidental, intentional self-harm, assault) cannot be determined. These sequelae can manifest in various organ systems, such as chronic respiratory issues, dermatological conditions, or kidney damage, that persist after the acute phase of toxicity has resolved.

Use this code when documenting a patient presenting with a chronic health condition definitively linked to a prior chromium exposure, and the original incident's intent is unknown or unspecifiable. This is appropriate for follow-up encounters addressing the lasting health consequences, not the initial acute poisoning event.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic bronchitis due to chromium).
• Ensure documentation clearly links the current condition to a past chromium exposure and explicitly states the undetermined intent.
• Do not use for acute chromium poisoning; this code is exclusively for the late effects.
