Poisn by cephalospor/oth beta-lactm antibiot, undet, init

This code signifies an adverse reaction to cephalosporin or other beta-lactam antibiotics where the intent of the poisoning (e.g., accidental, intentional self-harm, assault) cannot be determined. It indicates the patient is receiving active treatment for the toxic effects of the medication.

Use this code when a patient presents with symptoms of poisoning from a cephalosporin or beta-lactam antibiotic, and the medical record does not specify whether the poisoning was accidental, intentional, or due to assault. This code is appropriate for the initial visit or encounter where the poisoning is being evaluated and treated.

• Always assign an additional code for the specific manifestation(s) of the poisoning.
• Only use the "A" (initial encounter) seventh character for the first encounter related to the poisoning.
• If the intent of the poisoning is later determined, update the code to reflect the specific intent (e.g., accidental, intentional self-harm).
