Institutional provider Taxonomy code list

Institutional providers may submit a taxonomy code on claims they submit to Medicare. Medicare does not use the taxonomy code for matching a provider’s NPI to the appropriate legacy identifier. Medicare uses other claims data for this purpose. Medicare does not use the taxonomy code for any other claims processing purpose. Payers other than Medicare may have requirements for taxonomy codes. Medicare will pass any taxonomy code submitted on a Medicare claim to our trading partners on crossover claims, to allow for the possibility that those payers may use it.


If an institutional provider chooses to submit taxonomy codes, the following table supplies the crosswalk from Medicare’s legacy identifier (the OSCAR number) to the appropriate taxonomy code based on the provider’s facility type:
