Not sure whether you need to pay the application fee when enrolling, revalidating, or adding a location? A new tool from National Government Services can help you figure it out. “We’ve developed the Medicare Provider Enrollment Application Fee Decision Tree Tool to assist you in quickly identifying if an application fee is required for your provider enrollment application,” the HHH Medicare Administrative Contractor tells providers in a new message. Tip: “If you believe you qualify for a hardship exception, you may write a letter that explains the hardship and why that hardship justifies an exception and supply any supporting documentation,” NGS instructs. “Applicants submitting via paper must include the letter and supporting documentation with the application,” the MAC adds. “Applicants using PECOS must upload the letter and any supporting documents.” The tool is at www.ngsmedicare.com/web/ngs/medicare-pe-application-fee-decision-tree.
