Provider Transaction Access Number (PTAN) A PTAN is a Medicare-only number issued to providers by MACs upon enrollment to Medicare. When a MAC approves enrollment and issues an approval letter, the letter will contain the PTAN assigned to the provider.
Continued advances in medicine continuously change the rules and regulations behind Medicare. Obtaining a provider transaction access number (PTAN) is necessary for all health care providers who provide services to Medicare patients. This identifier is used to bill Medicare for medical services provided. Without a PTAN number medical provider billings to Medicare will be rejected and returned.
