How to Add a New Practice Location to Medicare, Medicaid, and Commercial Payers

Why Adding a Location Is a Payer Enrollment Event

A new practice location is not just a logistics change — it is an enrollment event that requires affirmative action with every payer your practice bills. Claims submitted from a location that has not been added to your enrollment record will be denied, and the timing of those denials is usually discovered weeks after opening, once billing begins. Adding a location must be coordinated in parallel with the physical opening, not after it.

What Changes (and What Doesn't)

Adding a location to an existing enrollment is different from a new enrollment: your NPI, EIN, CAQH profile, and contracted fee schedules typically carry over. What changes:

• Physical practice address in each payer's enrollment record
• Service location NPI association (Type 2 / group NPI linked to the new address)
• Rendering/service location on claims submitted from the new address
• Tax ID-to-address association for each payer
• Medicare pay-to address, if different from the service location

What does not automatically change (and should be reviewed regardless):

• Individual provider assignments to the location (each enrolled provider who will see patients at the new site may need to be added to the location record)
• CAQH ProView practice location list — must be updated and re-attested
• State Medicaid — each state may require a separate location update form distinct from federal PECOS

Step 1: Update NPPES

NPPES (the NPI registry) should be the first update after confirming the new address, because payer credentialing staff cross-reference NPPES during enrollment reviews. Log into nppes.cms.hhs.gov and add the new practice location as an additional address associated with your Type 2 NPI (group/entity). This is free and immediate. Confirm the update is visible in the registry before submitting enrollment updates to any payer.

Step 2: Update CAQH ProView

Add the new practice location in your CAQH ProView profile under Practice Locations. Include the physical address, phone, fax, office hours, and services available at that location. Re-attest the profile after adding the location — an un-attested update does not feed to commercial payers. The CAQH update takes effect within 24–48 hours of attestation and begins populating to payers that pull CAQH nightly.

Step 3: Update Medicare (PECOS)

Log into pecos.cms.hhs.gov and add the new practice location to your Group enrollment record (CMS-855B for group practices). Steps:

• Initiate a change of information application on your existing enrollment — do not start a new enrollment
• Navigate to the Practice Location section and add the new address
• Confirm the billing address (pay-to) and service address, which may be the same or different
• If any individual providers at the new location are not already reassigned to the group at Medicare, add their reassignment in this application
• Submit and note your confirmation number

Processing time: CMS currently estimates 30–60 days for change-of-information applications, though processing varies by MAC. Claims submitted from the new location before the update is processed may be denied; most practices stagger the location opening to avoid this gap or bill claims on hold pending the approval date.

Step 4: Update State Medicaid

State Medicaid programs operate separately from CMS and require their own update processes. Most states have online provider portal updates, but the fields required and the specific form (if paper) vary. General steps:

• Log into the state Medicaid provider portal for each state where the practice bills
• Locate the practice location change or facility update section
• Submit the new address and any required supporting documentation (some states require a lease or utility bill verifying the location)

Processing varies widely by state — some Medicaid programs update within 2 weeks; others take 60+ days. Confirm the effective date before submitting claims from the new location.

Step 5: Update Commercial Payers

Each commercial payer that is not using your CAQH ProView data for location updates must be notified separately. For payers that do pull CAQH nightly, the update will propagate within a few days of your CAQH re-attestation — but confirm this is the case for each payer rather than assuming. For payers that require separate notification:

• Log into the payer's provider portal and update practice location, or contact Provider Services to confirm the process for that specific plan
• Most commercial payers do not require a new credentialing application for an additional location if you are already contracted; they typically require a demographic update, which processes faster than a new credentialing application
• Medicare Advantage plans often have their own location update processes separate from the commercial product

Common Mistakes That Delay Billing

• Opening the location before submitting payer updates — the only way to avoid a billing gap is to submit updates well before the opening date
• Updating PECOS but not state Medicaid — these are entirely separate systems
• Updating CAQH but not re-attesting — CAQH does not push updates to payers until attestation is confirmed
• Forgetting individual provider assignments — at Medicare, each individual provider must be linked to the new location in PECOS
• Not confirming effective dates before billing — submit a test claim or confirm the effective date in writing from each payer before submitting live claims from the new location
