Has your doctor prescribed you an L3170 for your foot problems, but your unsure of what that really means? Medical billing codes essentially have been created to indicate what each orthosis does and what features they included. L-codes are like categories. For instance, the L3170 medical billing code pertains to a foot orthosis.
L3170 is the medical billing code for a foot orthosis shoe insert. This code indicates that the insert is made up of a plastic material, such as silicone or other comparable materials. Functionally this insert must be able to stabilize the heel. Like many shoe inserts, this insert comes ready made. In order for the L3170 code to apply to foot orthosis, which meet the above requirements, it must maintain it's "off the shelf" status. This means that the shoe inserts are not molded to fit any specific patient or customized in any way.
