Poisoning by cephalospor/oth beta-lactm antibiot, acc, subs

This code signifies an adverse reaction to cephalosporin or other beta-lactam antibiotics due to an accidental overdose or incorrect administration, occurring during a follow-up visit for the initial poisoning event. The patient is experiencing ongoing effects or complications from the unintentional exposure to these medications.

Use this code for patients presenting for subsequent care related to an accidental poisoning by antibiotics such as cefazolin, amoxicillin, or penicillin. This includes follow-up appointments for monitoring organ function, managing persistent symptoms, or addressing complications that arose from the initial toxic exposure.

• Ensure documentation clearly states the poisoning was accidental and that this is a subsequent encounter.
• Always code the specific antibiotic involved if known, using additional codes from categories T36-T50.
• Consider adding codes for any associated symptoms or adverse effects experienced by the patient.
