Per Clinical Coverage Policy 5A-3, Nursing Equipment and Supplies on the NC Medicaid website, HCPCS code A4252 (blood ketone test or reagent strip, each) has a quantity limitation of 100 test strips per month. Considering the national description of A4252 refers to each test strip, DME providers are reminded to submit their claims with the number of test strips supplied to the beneficiary, not the number of boxes of test strips.
