Toxic effect of unsp alcohol, undetermined, subs encntr

This code signifies a toxic reaction to an unspecified type of alcohol where the intent (e.g., accidental, intentional self-harm) cannot be determined. The "subsequent encounter" indicates that the patient is receiving follow-up care for the initial toxic effect, such as monitoring, rehabilitation, or treatment of residual symptoms.

This code is appropriate for patients presenting for ongoing management of symptoms or complications stemming from an alcohol toxicity event when the specific type of alcohol ingested is unknown and the circumstances surrounding the exposure are unclear. It is used after the initial acute phase of treatment.

• Ensure documentation clearly supports an "undetermined" intent and an "unspecified" alcohol type.
• Reserve this code for follow-up visits; an initial encounter would use the "A" seventh character.
• Always sequence this code after any codes for specific manifestations of the toxic effect.
