A four-provider orthopedic group signs a lease on a second office across the county. The build-out takes four months, the staff are hired, the schedule fills, and the first month of claims from the new address comes back with denials the group has never seen: provider not enrolled at this location, service location not on file, billing provider address mismatch. Nobody thought of the payers because the providers were already credentialed. They were. The location was not.
We see this often enough that it deserves its own article. Adding a location is not the same as adding a provider, and it is not nothing. Every payer keeps a record of where your group renders services, and most of them will not pay for services at an address they do not have on file. The work is not hard. It is a dozen forms to a dozen organizations, each on its own clock, and the only way it goes well is if one person owns the list and starts the day the lease is signed.
Key takeaways
- Payers pay by location: contracts, locality-adjusted rates, directories and Medicare site verification all key off the service address, so an unknown address denies or pays wrong.
- The order is NPPES, then the CMS-855B through PECOS, then state Medicaid and its managed care plans, then CAQH, then each commercial payer's location form, then CLIA, DEA and the clearinghouse.
- Medicare requires a practice location change to be reported within 30 days, and the slowest commercial payers can take 90 days, so a 120-day runway before opening is about right.
- Hold new-location claims per payer until each approval arrives; a hold is one touch, a denial and resubmission is three.
- The most expensive mistake is changing the pay-to address when you meant to add a service location.
Why payers care about the address
Payers use the service location for several things: matching the claim to a contract (some contracts are location specific), confirming the place of service code makes sense, paying at a locality-adjusted rate (Medicare fee schedules vary by locality, so a new office in a different locality changes the allowed amount), directing patients through the provider directory, and, for Medicare, verifying that the location exists and is operational. The Medicare Administrative Contractor (MAC) may visit the address. A claim whose service facility address does not match a payer record either denies or, worse, pays at the wrong rate quietly, and the quiet version can run for a year before anyone notices the allowed amounts are off.
On the claim itself, the address lives in the service facility location loop (2310C on the 837P), separate from the billing provider address (2010AA) and the pay-to address (2010AB). Those three fields are the source of most of the confusion. The billing provider and pay-to addresses usually do not change when you add an office. The service facility address does, on every claim from the new site.
The order of operations
- NPPES first. Add the new practice location to the group's Type 2 NPI record and to each provider's Type 1 record if they will work there. This is free, immediate and the record other systems check against. NPPES allows multiple practice locations on one NPI; use that rather than applying for a new NPI, which creates a second identity you will regret.
- Medicare next. Submit a CMS-855B change of information through PECOS to add the practice location to the group enrollment. In PECOS this is a change request against the existing enrollment; you add the location in the practice location section with the address, phone, hours and the date you will begin seeing patients there, and an authorized or delegated official signs the certification electronically. Medicare requires you to report a new practice location within 30 days of the change. Processing by the MAC typically takes 45 to 90 days in our experience. Medicare generally sets the effective date at the later of the date the request was received or the date services began at the location, with only a short retrospective window, so file before the first patient day, not after.
- Medicaid and Medicaid managed care. Each state has its own process. Some states enroll each service location separately with its own identifier; others attach locations to the group record. The managed care plans then have their own forms. Start this at the same time as Medicare because state processing times are the least predictable, and ask each managed care plan whether it reads the state file or needs its own update. Most need their own.
- CAQH ProView. Add the location to every provider's profile and re-attest. Most commercial payers will pull the location from here, and an unattested profile blocks the whole update. Confirm the practice location section, the billing contact and the office hours, because payer directories publish exactly what is in the profile.
- Commercial payers. Each has a location add or demographic change form, usually available on the provider portal. Some process a location add in two weeks; some route it through their credentialing committee and take 90 days. Ask each payer whether the new location needs a separate contract amendment or is covered by the group agreement, and get the answer in writing with a reference number.
- Everything else. The clearinghouse (a new billing address or pay-to address can affect ERA and EFT enrollment), CLIA if the new office will run lab tests (a new certificate per location), state facility licenses where they apply, the DEA if controlled substances will be stored at the new address, your malpractice carrier, and the practice management system, where the new location needs its own record with the correct place of service and the right NPI and taxonomy attached.
A realistic timeline
| Step | Start | Typical completion |
|---|---|---|
| NPPES location update | Day the lease is signed | Same day |
| CMS-855B via PECOS | As soon as the address and phone are final | 45 to 90 days |
| State Medicaid and MCO location enrollment | Same week as PECOS | 30 to 120 days, varies by state |
| CAQH update and re-attestation | Same week | Days, but payers pull on their own schedule |
| Commercial payer location forms | After CAQH | 2 to 12 weeks per payer |
| CLIA certificate for the new site | Before any testing begins | Several weeks |
| Practice management and clearinghouse setup | 30 days before opening | A week, plus a test claim |
If the new office opens in 90 days, you are already late on the slow payers. If it opens in 120 days, you are about right. Most groups tell us the real estate timeline was set a year in advance and the payer timeline was discovered a month before opening.
A worked example with dates
Take the orthopedic group from the opening, fictional but typical, with the lease signed on February 1 and a target opening of June 3. Here is the sequence we would run.
| Date | Action | Result |
|---|---|---|
| Feb 1 | NPPES: add location to group NPI and four Type 1 NPIs | Live same day |
| Feb 12 | PECOS 855B change request filed with June 3 start date; state Medicaid location form filed | Reference numbers logged |
| Feb 14 | CAQH profiles updated and re-attested for all four providers | Complete |
| Feb 20 to Mar 1 | Location forms to six commercial payers; two require contract amendments | Follow-up dates set at 30 days |
| Apr 9 | MAC approves 855B, effective June 3 | Medicare hold can be released on opening |
| Apr 15 to May 24 | Four commercial approvals arrive; two amendments still pending | Two payers stay on hold |
| Jun 3 | Opening day; test claim to each approved payer | Claims for two pending payers held |
| Jun 28 | Last amendment signed; hold released, 41 claims submitted | No location denials |
Notice that the state Medicaid approval is not in the table. In this example it arrived in late July, which is why the group scheduled Medicaid patients at the original office until then. That decision cost nothing. Scheduling them at the new site would have produced two months of denials.
Claim holds that save the first quarter
Set a hold in the practice management system for claims with the new service location and a payer whose location approval has not arrived. Release the hold per payer as approvals come in. Without this, claims go out, deny, get worked as denials, and eventually get resubmitted, which is three touches instead of one. Track the hold balance weekly; if it climbs past two months of the new location's charges, escalate with the payers rather than waiting. Timely filing still runs while a claim sits on hold, so the tracker needs the oldest date of service for each payer on it.
Use the right place of service code from day one. A new office is POS 11. If the new site is a hospital-owned outpatient department under a different arrangement, the codes and the enrollment are different (POS 19 or 22), and that is a conversation to have before the lease, not after.
Mistakes we see
Updating the billing address instead of adding a service location. Those are different fields on every form, and changing the pay-to address by mistake can redirect checks and break EFT. Forgetting the providers' individual records: the group location is added but the individual provider is not linked to it, so claims deny for the rendering provider rather than the group. Skipping the reattestation on CAQH after the update. Assuming Medicaid managed care plans read the state's file; they usually do not. And letting the practice management vendor create the new location record without checking the taxonomy code and NPI attached to it, which produces a rejection at the clearinghouse before the payer ever sees the claim.
Questions we hear
Can we see patients at the new location before the payers approve it?
You can see them. Whether you can bill depends on the payer's retroactive policy. Medicare will generally honor the effective date on the approved 855B if you filed before or close to the start date. Many commercial payers will not pay for a location before their approval date. Schedule the first weeks at the new site with patients on plans that have already approved, or that you know allow retroactive billing.
Does a location add restart provider credentialing?
Usually not. Providers already credentialed with the group stay credentialed. The location is a demographic change to the group record. The exception is a payer whose contract is written per location, in which case there may be a contract amendment, and a few payers that treat any change as a trigger to re-verify the group's documents.
Who should own this?
One person, with a spreadsheet listing every payer, the form used, the date submitted, the reference number, the follow-up date and the approval date. Revelrex credentialing and provider enrollment handles location adds as a per-application service with this tracking visible to the practice; rates are on the pricing page.
What to do this month
- If a new site is planned, count backward 120 days from opening and put the NPPES, PECOS and Medicaid filings on the calendar this week.
- Build the payer tracker: payer, form, date filed, reference number, follow-up date, approval date, effective date.
- Ask every commercial payer in writing whether the new location is covered by the group contract or needs an amendment.
- Confirm CLIA, DEA and malpractice coverage for the new address before the first test, prescription or visit.
- Set the per-payer claim hold in the practice management system and schedule a weekly review of the hold balance.
- Send a test claim to each approved payer in the week before opening and read the 277CA.
