Medical necessity is established by the presence of a clinically significant adverse reaction or poisoning related to the use of topical antifungal, anti-infective, or anti-inflammatory medication.Documentation should support the diagnosis and justify the level of treatment provided.
The clinical responsibility depends on the setting. In an outpatient setting, a physician or other qualified healthcare professional would document the diagnosis and treatment.In an inpatient setting, this falls under the responsibility of the attending physician.
In simple words: This code is used when someone experiences a problem (poisoning, side effect, or not enough medicine) from using a cream, ointment, or other topical medicine that fights infection, reduces inflammation, or treats fungus on their skin.This includes accidental overdoses, using the wrong medicine, or not using enough medicine.
This code classifies poisoning, adverse effects, or underdosing resulting from the topical application of antifungal, anti-infective, and anti-inflammatory drugs.It includes situations where the drug was correctly administered but caused an adverse reaction, an overdose occurred, the wrong drug was administered, or an underdose was given intentionally or unintentionally.This code should be used when the specific drug causing the adverse effect is not specified elsewhere and is not a glucocorticoid.Additional codes may be required to specify the manifestation of poisoning or the underdosing or failure in dosage during medical or surgical care.The specific drug involved should be identified using codes from categories T36-T50 with the fifth or sixth character 5.
Example 1: A patient applies a topical antifungal cream for athlete's foot, experiences severe skin irritation, and presents to the clinic.The diagnosis is T49.0.Further investigation is needed to identify the specific antifungal agent to use for the T36-T50 codes., A patient uses a topical anti-inflammatory cream prescribed for eczema. They develop a contact allergic reaction, with significant skin rash and itching. T49.0 is diagnosed, along with additional codes to describe the allergic reaction., A child accidentally ingests a significant amount of a topical antibiotic ointment.The parent brings them to the emergency room where T49.0 is coded, along with additional codes specifying the type of antibiotic and the child's symptoms.
