Coding and Edits

"What If" and Scenario Questions

Physician offices often contact us with different scenarios and "what if?" questions regarding coding and documentation for a particular service(s). Providers ask the contractors for a definitive response on whether Medicare would make payment. While Medicare contractors can provide information on Medicare rules and regulations, the final determination is based on information contained in an individual patient’s medical record.

Medicare representatives are available to indicate whether a service is a payable service under Medicare guidelines, but cannot instruct a provider or provide a statement that a specific patient's service is payable or provide instructions on how to code a service. Additionally, contractors may not provide a preliminary medical review determination based on snippets of information or documentation. The final determination of payment is made after the submission of the claim and any medical review that may be performed. MACs will not grant prior approval or affirm a provider’s individual practice’s procedures, coding or documentation are sufficient to meet all Medicare guidelines.

Remember, providers are responsible for determining the correct diagnostic and procedural coding for the services furnished to Medicare patients. After reviewing Medicare guidelines, providers, compliance, audit and/or billing staff can find more information on coding resources in the CMS IOM Publication 100-09, Medicare Administrative Contractor (MAC) Beneficiary and Provider Communications Manual, Chapter 6, Section 30.3.1

If you have a question about interpretation of procedural and diagnostic coding, please contact the entities that have responsibility for those coding sets.
