Poisoning by, adverse effect of, and underdosing of systemic antibiotics.
Medical necessity for the treatment of poisoning, adverse effects, or complications arising from antibiotic use should be clearly documented. The documentation must support the need for the level of care provided.
Clinicians are responsible for correctly identifying the causative agent, documenting the circumstances of the poisoning or adverse effect, and providing appropriate treatment and supportive care.
In simple words: This code represents a problem related to systemic antibiotic use, including taking too much, taking the wrong one, or not taking enough. It also covers negative side effects, even if the medication is taken correctly.
This code encompasses poisoning by, adverse effects of, and underdosing of systemic antibiotics.It includes adverse effects from correctly administered substances, poisoning by overdose, and poisoning by the wrong substance given or taken in error.It also includes underdosing by inadvertently or deliberately taking less of a substance than prescribed.
Example 1: A patient intentionally overdoses on penicillin, requiring emergency medical treatment., A patient experiences severe gastrointestinal upset after taking a prescribed course of amoxicillin, requiring a change in medication., A patient mistakenly ingests their pet's antibiotic medication, leading to an adverse reaction and a visit to the emergency room.
Documentation should include the specific antibiotic involved, the route of administration, the dosage taken (if known), the time of ingestion or administration, the symptoms experienced, and any treatment provided.For adverse effects, document the nature of the reaction and its severity.
** Excludes1: antineoplastic antibiotics (T45.1-) locally applied antibiotic NEC (T49.0) topically used antibiotic for ear, nose and throat (T49.6) topically used antibiotic for eye (T49.5). For underdosing, use additional codes to specify manifestations of poisoning (e.g., underdosing during medical and surgical care (Y63.6, Y63.8-Y63.9), underdosing of medication regimen (Z91.12-, Z91.13-)).
