For healthcare providers looking to expand their patient base and establish a stable revenue stream, becoming an in-network Medicare provider represents a significant opportunity. With over 66 million Americans enrolled in Medicare, this federal health insurance program serves as a cornerstone of healthcare coverage in the United States. However, the process of joining Medicare’s network can feel daunting, particularly for new practitioners or those transitioning from other insurance models.
What Does Being In-Network Mean?
When you’re in-network with Medicare, you’ve agreed to accept Medicare’s approved payment amounts for covered services. This arrangement provides benefits for both you and your patients. Your patients gain access to predictable out-of-pocket costs, while you receive a steady flow of patients who know they can see you without facing surprise bills or higher costs associated with out-of-network care.
The distinction between participating and non-participating providers is important to grasp. Participating providers accept assignment for all Medicare claims, meaning they agree to accept Medicare’s approved amount as full payment. Non-participating providers can choose whether to accept assignment on a claim-by-claim basis, but they face limitations on how much they can charge patients and receive only 95% of Medicare’s fee schedule.
Why Join Medicare’s Network?
The decision to become a Medicare provider affects your practice in several meaningful ways. First, there’s the patient volume consideration. Baby boomers continue aging into Medicare eligibility, creating an expanding pool of potential patients. Many beneficiaries actively seek providers who accept Medicare, and being in-network makes you visible in Medicare’s provider directories.
From a financial perspective, Medicare offers reliable reimbursement. While rates may be lower than some private insurance payments, Medicare pays consistently and processes claims efficiently. You’ll also avoid the uncertainty of out-of-network billing and the administrative burden of balance billing patients.
Additionally, many Medicare Advantage plans require that physicians be enrolled in Original Medicare before they can join their networks. By establishing yourself as a Medicare provider, you open doors to additional managed care opportunities.
Eligibility Requirements
Before you can enroll in Medicare, you need to meet specific criteria. You must hold a valid professional license in your state and maintain it in good standing. Your practice must have a physical location where you see patients, and you’ll need a National Provider Identifier (NPI) number.
Medicare also conducts background checks as part of the enrollment process. They’ll review your license history, check for any sanctions or exclusions from federal healthcare programs, and verify that you haven’t been convicted of certain criminal offenses. Any adverse actions on your record could delay or prevent enrollment.
The Enrollment Process Step by Step
Getting enrolled in Medicare involves several stages, each requiring attention to detail and proper documentation. The process typically takes between 60 to 90 days, though it can extend longer if issues arise with your application.
Step 1: Obtain Your NPI Number
If you don’t already have one, you’ll need to apply for an NPI through the National Plan and Provider Enumeration System (NPPES). This unique identification number follows you throughout your career and is required for all electronic healthcare transactions.
Step 2: Complete the CMS-855 Application
The CMS-855 enrollment application is the cornerstone of Medicare enrollment.
The specific form you’ll complete depends on your provider type:
- CMS-855I: Individual physicians and non-physician practitioners
- CMS-855B: Clinics, group practices, and other organizational providers
- CMS-855A: Institutional providers like hospitals
- CMS-855S: Durable medical equipment suppliers
These applications require detailed information about your practice, including ownership structure, practice locations, specialties, and any relationships with other healthcare entities. You’ll also need to provide supporting documentation such as copies of your medical license, DEA certificate if applicable, and professional liability insurance information.
Step 3: Enroll Through PECOS
The Provider Enrollment, Chain, and Ownership System (PECOS) is Medicare’s online enrollment platform. You’ll create an account, complete your application electronically, and upload required supporting documents. The system allows you to track your application status and respond to any requests for additional information.
Step 4: Undergo Background Screening
Medicare will conduct fingerprint-based background checks for certain provider types and risk categories. You may need to schedule an appointment at a designated location for fingerprinting.
Step 5: Receive Your Medicare Number
Once approved, you’ll receive a formal notification and be assigned a Medicare Provider Transaction Access Number (PTAN). This number identifies you in Medicare’s system for claims submission and reimbursement.
Common Roadblocks and How to Avoid Them
Many providers encounter obstacles during the enrollment process. Incomplete applications represent one of the most frequent issues. Missing signatures, unsigned attestations, or omitted sections will result in delays or rejections. Review every page of your application carefully before submission.
Documentation problems also create setbacks. Make sure your supporting documents are current, clearly legible, and match the information on your application exactly. Discrepancies between your application and supporting materials will trigger requests for clarification.
Address issues present another common stumbling block. Medicare requires that your practice address matches your state license, NPI record, and other official documents. Even minor variations like “Street” versus “St.” can cause problems.
Maintaining Your Medicare Enrollment
Getting enrolled is just the beginning. Medicare requires providers to revalidate their enrollment periodically, typically every five years.
You’ll also need to report any changes to your practice within 30 days, including:
- Changes in practice location
- Changes in ownership or organizational structure
- Changes in contact information
- Addition or departure of practice members
- Changes to your state license status
Failing to report changes or complete revalidation on time can result in deactivation of your Medicare billing privileges, interrupting your revenue stream and requiring you to go through the entire enrollment process again.
Electronic Prescribing and Quality Reporting
Modern Medicare participation involves more than just submitting claims. You’ll need to participate in the Quality Payment Program, which includes either the Merit-based Incentive Payment System (MIPS) or Advanced Alternative Payment Models (APMs). These programs tie a portion of your reimbursement to quality metrics and reporting requirements.
Electronic prescribing of controlled substances has also become standard practice. While not universally required, many Medicare Advantage plans and quality programs expect electronic prescribing capability.
Working with Professional Services
Given the administrative demands of Medicare enrollment and maintenance, many practices turn to specialized services for support. This is where companies like Medwave come into play. Medwave specializes in billing, credentialing, and payer contracting, helping healthcare providers manage the administrative side of their practice while they focus on patient care.
Professional credentialing services can streamline the enrollment process by ensuring applications are complete and accurate before submission, tracking deadlines for revalidation, maintaining compliance with reporting requirements, and handling communication with Medicare contractors. This support proves particularly valuable for small practices or solo practitioners who lack dedicated administrative staff.
Looking at Medicare Advantage
Once you’re enrolled in Original Medicare, you may want to explore contracts with Medicare Advantage plans. These private insurance plans receive payment from Medicare to provide Part A and Part B benefits, and often include additional coverage. Each plan maintains its own provider network and credentialing requirements.
Contracting with Medicare Advantage plans requires separate applications and negotiations with each plan. The reimbursement rates, prior authorization requirements, and administrative processes vary significantly between plans. Many providers find that working with a contracting specialist helps them evaluate opportunities and negotiate favorable terms.
Summary: In-Network with Medicare
Becoming an in-network Medicare provider opens your practice to millions of potential patients and establishes a foundation for long-term growth. While the enrollment process requires careful attention to detail and patience, the benefits of Medicare participation typically outweigh the administrative investment.
Start the process early, gather your documentation thoroughly, and consider whether professional support might help you avoid common pitfalls. Whether you choose to handle enrollment independently or work with a service like Medwave for your billing, credentialing, and payer contracting needs, the key is ensuring accuracy and completeness at every step. With proper preparation and follow-through, you’ll be seeing Medicare patients and building that portion of your practice before you know it.
