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

This code signifies a poisoning event involving cephalosporin or other beta-lactam antibiotics where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. It is used when a patient is presenting for follow-up care after the initial treatment of such a poisoning.

This code is appropriate for subsequent encounters related to a cephalosporin or beta-lactam antibiotic poisoning when the intent is unknown. Examples include follow-up appointments for monitoring organ function, managing lingering side effects, or addressing complications that arose from the initial poisoning.

• Always assign an additional code for the specific adverse effect or manifestation of the poisoning.
• Ensure documentation clearly states that the intent of the poisoning is undetermined.
• This "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
