All Provider Information Request (PIR) files will need to adhere to the following file naming convention.

The naming convention should follow this format:

9999xxyyyy.pnnnnn

9999 = provider code (numeric)

xx = abbreviated file type code (i.e. PCO or pco)

yyyy = reporting year (numeric; must be >=2016)

p = reporting period (numeric; always 1)

nnnnn = submission number (numeric; 00001 to 99999)

For the purpose of this example, the test provider code 9998 has been used, and examples refer to the first file of each type reported for 2017.
