English to Russian Medical Medical (general)

Patients treated with Xr-NTX were identified on the basis of an outpatient drug claim from the National Drug Code (Ndc) or medical claims from the Healthcare Common Procedure Coding System code (because it is the 1 agent administered with a procedure).
The other medications were identified using outpatient drug claims based on Ndcs. For patients in the no medication group, the index date was defined as the first medical claim for a nonpharmacologic treatment, such as a detoxification facility claim, a substance abuse treatment facility claim, or a substance abuse counseling claim.
