Poisoning by other specified antibiotics

This code signifies an adverse reaction or toxic effect resulting from the ingestion, injection, or application of an antibiotic not specifically classified elsewhere. It encompasses poisonings from antibiotics that are identified but do not have a more specific ICD-9-CM code. This could involve an overdose, accidental ingestion, or an idiosyncratic reaction to the drug.

Use this code when documentation clearly indicates poisoning by an antibiotic that is specified (e.g., vancomycin, clindamycin, metronidazole) but does not fall under a more granular code within the 960 series. The patient's medical record should detail the specific antibiotic involved and the nature of the poisoning (e.g., accidental, intentional, adverse effect).

• Always code the specific antibiotic if a more precise code is available within the 960 series.
• Remember to also code the manifestation of the poisoning (e.g., acute renal failure, hepatic necrosis) as an additional diagnosis.
• Distinguish between poisoning (adverse effect due to incorrect use or overdose) and adverse effect in therapeutic use (995.2x series), which is for correctly administered drugs.
