What Is an S Code in Medical Billing

The only associated definition is broadly written as “Routine ophthalmological examination including refraction.” S codes are traditionally used in cases in which there are no nationally accepted CPT codes for reporting the use of medications, medical supplies or services.

Does Medicare pay S codes?

Medicare does not reimburse for services under S codes.

What are K codes?

K codes are used by Durable Medical Equipment Medicare Administrative Contractors (DME MACs). DME MACs develop new K codes when existing national codes for supplies and certain product categories do not include the codes needed to implement a DME MAC medical review policy.
