Toxic effect of chlorofluorocarbons, undetermined, subs

This code signifies a toxic reaction to chlorofluorocarbons (CFCs) where the intent of exposure is unknown. It is used for encounters following the initial treatment for the poisoning, indicating ongoing management or follow-up related to the toxic effect.

Apply this code for patients presenting for follow-up care, monitoring of long-term effects, or further treatment after an initial diagnosis of CFC poisoning with an undetermined intent. This is appropriate when the patient has already received acute care for the initial exposure.

• Ensure the encounter is not the initial visit for the poisoning; otherwise, use the appropriate initial encounter character.
• Confirm the intent of the exposure remains undetermined; if intent is clarified, select a more specific code.
• Always code any associated signs, symptoms, or specific organ damage resulting from the CFC toxicity.
