Ordering & Referring Information

Important Update on PECOS & Ordering/Referring

CMS will instruct contractors to turn on Phase 2 denial edits on  January 6, 2014.  These edits will check the  following claims for a valid individual National Provider Identifier (NPI) and deny the claim when this information is invalid:

• Claims from clinical laboratories for ordered tests;
• Claims from imaging centers for ordered imaging procedures;
• Claims from suppliers of Durable Medical Equipment, Prosthetics, Orthotics, and Supplies (DMEPOS) for ordered DMEPOS; and
• Claims from Part A Home Health Agencies (HHAs).

For more information refer to MLN Matters article #SE1305 under the Educational Materials section

• MLN Matters® Article #SE1305, “Full Implementation of Edits on the Ordering/Referring Providers in Medicare Part B, DME, and Part A Home Health Agency (HHA) Claims (Change Requests 6417, 6421, 6696, and 6856)”

Effective April 7, 2014, CMS has instructed contractors to deny certain Power Mobility Devise (PMD) DMEPOS claims identifying an ordering/referring physician or non-physician practitioner who is not of an authorized specialty.  For more information refer to MLN Matters article #MM8239 under the Educational Materials section.

About the Ordering and Referring Files

The downloads below contain the National Provider Identifier (NPI) and legal name (last name, first name) of all physicians and non-physician practitioners who are of a type/specialty that is legally eligible to order and refer Part B (clinical laboratory and imaging), DME and HHA claims, in the Medicare program and who have current enrollment records in Medicare (i.e., they have enrollment records in PECOS). A separate file is also available identifying those physicians and non-physician practitioners that are eligible to order and refer PMD and have a current enrollment record in Medicare.

To keep the available information up to date, CMS will replace the Report twice a week. At any given time, only one Report (the most current) will be available for downloading. The file can be downloaded by users with technical expertise and further sorted or manipulated. It can also be used to search for a particular physician or non-physician practitioner by NPI or by name. Please note the following: (1) Records are in alphabetical order based on the surname of the physician or non-physician practitioner. (2) Name suffixes (e.g., Jr.), if they exist, are not displayed. (3) There are no “duplicates” in the file. Many physicians or non-physician practitioners share the same first and last name; their corresponding NPIs are the assurance of uniqueness. (4) Deceased physicians and non-physician practitioners are not included in the file.
