Medicare enrollment applications typically take between 60-90 days to process, though this can vary significantly between states. The effective date for Medicare is set as the date the application was received, allowing providers to retroactively bill for services rendered from the application date to the approval date. Additionally, there is a 30-day grace period that permits providers to bill for services provided up to 30 days before their effective date.
For DMEPOS suppliers, the process takes longer. Applications undergo thorough scrutiny, including a mandatory site visit. During the site visit, inspectors verify the office location, hours of operation, inventory storage, and other critical aspects of being a DME supplier.
