HCPCS Code A4556: Electrodes, (e.g., Apnea Monitor), Per Pair

It can, but many payers—including Medicare and commercial insurers—consider it bundled into the primary service or put allowances under inclusive codes like A4595. Always verify payer policy.

Use A4595, which includes electrodes, adhesive, batteries, and more on a monthly supply basis. Separate billing for electrodes (A4556), gel (A4558), or batteries (A4630) is not allowed.

Some patients might feel discomfort. It's also possible for adhesives attached to the electrodes to cause skin irritation or trigger allergic reactions.
