Toxic effect of oth substances, assault, subs encntr

This code signifies a harmful physiological response resulting from intentional exposure to a specified substance not categorized elsewhere, occurring during the recovery phase or follow-up care. The patient is experiencing ongoing effects or complications from a deliberate act of poisoning by another party.

Apply this code for patients presenting for follow-up appointments, medication adjustments, or management of persistent symptoms directly related to a previous toxic exposure that was determined to be an assault. This includes situations where the patient is recovering from the acute effects but still requires medical attention for related sequelae.

• Ensure documentation clearly states the toxic effect is due to an assault and that it's a subsequent encounter.
• Always code the specific substance if known, using an additional code from T36-T50 if applicable.
• Do not use for initial encounters or for accidental or self-harm exposures.
