Frequently asked questions

Yes, HCPCS code A4253 is covered by Medicare when the patient meets the criteria for using a home blood glucose monitor, which includes being diagnosed with diabetes. The supplies must also be considered "reasonable and necessary" for the patient's treatment.

If a patient requires more test strips than the standard limits, additional documentation from the treating physician is necessary. This documentation must justify the medical need for a higher testing frequency.

No, you cannot. A common billing error is to bill the same number of units for both test strips (A4253) and lancets (A4259). One unit of A4253 is 50 strips, while one unit of A4259 is 100 lancets. Always bill the correct number of units for each code based on the quantity supplied.
