Toxic effect of beryllium and its compounds, undet, sequela

This code signifies a long-term health problem or complication resulting from a past exposure to beryllium or its compounds, where the intent of the exposure (accidental, intentional self-harm, assault) is unknown. These sequelae can manifest as chronic respiratory conditions, skin disorders, or other systemic effects that persist after the acute phase of toxicity has resolved.

Apply this code when documenting a chronic or residual condition directly attributable to beryllium exposure that occurred in the past, and the medical record does not specify whether the exposure was accidental, intentional, or assault-related. This is appropriate for follow-up encounters addressing the ongoing management of such conditions.

• Always sequence this sequela code after the code for the specific chronic condition caused by the beryllium toxicity.
• Ensure documentation clearly links the current condition to a past beryllium exposure.
• Only use the "S" seventh character for sequelae when the acute toxic event has passed and the patient is receiving treatment for the residual effects.
