Local Coverage
For the most part, codes are no longer included in the LCD (policy). You will find them in the Billing & Coding Articles. Try using the MCD Search to find what you're looking for. Enter the code you're looking for in the "Enter keyword, code, or document ID" box. The list of results will include documents which contain the code you entered.
Please Note: For Durable Medical Equipment (DME) MACs only, CPT/HCPCS codes remain located in LCDs. All other Codes (ICD-10, Bill Type, and Revenue) have moved to Articles for DME MACs, as they have for the other Local Coverage MAC types.
National Coverage
NCDs do not contain claims processing information like diagnosis or procedure codes nor do they give instructions to the provider on how to bill Medicare for the service or item. For this supplementary claims processing information we rely on other CMS publications, namely Change Requests (CR) Transmittals and inclusions in the Medicare Fee-For-Service Claims Processing Manual (CPM).
In order for CMS to change billing and claims processing systems to accommodate the coverage conditions within the NCD, we instruct contractors and system maintainers to modify the claims processing systems at the national or local level through CR Transmittals. CRs are not policy, rather CRs are used to relay instructions regarding the edits of the various claims processing systems in very descriptive, technical language usually employing the codes or code combinations likely to be encountered with claims subject to the policy in question. As clinical or administrative codes change or system or policy requirements dictate, CR instructions are updated to ensure the systems are applying the most appropriate claims processing instructions applicable to the policy.
