Poisoning by anticoagulants, undetermined, subs encntr

This code signifies an adverse effect or toxic reaction to an anticoagulant medication where the intent (e.g., accidental, intentional self-harm) cannot be determined. The patient is receiving active treatment for the poisoning during this encounter, but it is not the initial visit for the condition.

Apply this code when a patient presents for follow-up care or continued management of anticoagulant poisoning, and the circumstances surrounding the poisoning remain unclear. This is appropriate for encounters after the initial diagnosis and treatment have begun, but the patient is still experiencing effects or complications.

• Requires an additional code to specify the anticoagulant drug involved (e.g., from T45.5X- category).
• The 7th character "D" indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use if the intent of the poisoning is known (e.g., accidental, intentional self-harm, assault).
