Poisn by cephalospor/oth beta-lactm antibiot, acc, sequela

This code describes the long-term effects or complications arising from an accidental overdose or incorrect administration of cephalosporin or other beta-lactam antibiotics. These sequelae are the residual conditions that persist after the acute phase of the poisoning has resolved.

Use this code when documenting chronic conditions, organ damage, or other lasting health problems directly attributable to a past, unintentional poisoning by cephalosporin or beta-lactam antibiotics. This applies to follow-up encounters for managing these persistent effects, not the initial acute poisoning event.

• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated.
• Ensure documentation clearly links the current condition to a past accidental cephalosporin/beta-lactam poisoning.
• Do not use this code for acute poisoning events; instead, use the appropriate acute poisoning code from the T36.1X1 category.
