ICD-10-CM T49.0X2: Poisoning by local antifungal, anti-infective and anti-inflammatory drugs, intentional self-harm
The ICD-10-CM code T49.0X2 represents a diagnosis of poisoning by local antifungal, anti-infective, and anti-inflammatory drugs involving intentional self-harm. This code is documented within the ICD10CM system. Public health research tracking inpatient diagnoses during the COVID-19 lockdown noted reductions in accidental injury and poisoning diagnoses, alongside reductions in the intentional self-harm subgroup. 5 6 1
What this code represents
The ICD-10-CM code T49.0X2 is explicitly associated with the descriptor for poisoning by local antifungal, anti-infective and anti-inflammatory drugs, intentional self-harm. This code is listed within the ICD10CM code system. 5 6
Plain-language overview
A CDC National Health Statistics report lists T49.0x2 as poisoning by local antifungal, anti-infective and anti-inflammatory drugs, intentional self-harm. This listing places the concept alongside other specific intentional self-harm poisoning codes like T36.7x2 and T39.392. 2
What the sources add
A CDC report lists T49.0x2 as poisoning by local antifungal, anti-infective and anti-inflammatory drugs, intentional self-harm, while CMS billing articles separately list adverse effects of local antifungal, anti-infective and anti-inflammatory drugs. This comparison shows the sources distinguish between poisoning and adverse effect concepts. 2 3 4
Clinical context
A study using ICD-10 coding to analyze missing pediatric inpatient diagnoses during a nationwide lockdown observed a net decrease in accidental injury and poisoning diagnoses. The study also noted significant reductions in the intentional self-harm subgroup without any increased mental health diagnosis in 2020. 1
Coverage and utilization context
CMS billing and coding articles for Serum Magnesium and RAST Type Tests include references to adverse effects of local antifungal, anti-infective and anti-inflammatory drugs. These references appear within Medicare coverage database articles that address billing and coding guidelines. 3 4
Documentation considerations
The official descriptor for T49.0X2 explicitly includes the terminology for intentional self-harm. The EVS Explore source lists this exact descriptor alongside the T49.0X2 code within the ICD-10 framework. 5
Coding details
The National Health Statistics Reports source lists the code using a lowercase x in the format T49.0x2. The EVS Explore and VSAC sources list the code using an uppercase X in the format T49.0X2 within the ICD10CM system. 2 5 6
