The Massachusetts Confirmation of Provider Form tells your workers’ compensation insurer which doctor or facility is treating your workplace injury so that medical bills and case correspondence get routed to the right place. You fill it out with your identifying information, your claim number, and your provider’s credentials, then send it to the insurer’s claims office. Below is what to have on hand, how to submit it, and what the form actually does for your claim.
Information to Gather Before You Start
Blanks and mismatches are the most common reasons a filing stalls, so pull these details together first. Each entry should match the records the medical office has on file; a provider name that doesn’t line up with the name registered to the NPI, for example, can trigger a rejection.
- Your full legal name, Social Security number, and the date of your workplace injury.
- Your insurer claim number. It appears on correspondence from the carrier and ties every piece of medical billing to your open case. Check it against an existing letter or explanation of benefits before you write it in.
- The provider’s full legal name and specialty, exactly as it appears in official records rather than a nickname or informal practice name.
- The provider’s National Provider Identifier, a unique ten-digit number. If you don’t have it, search the CMS NPPES registry at npiregistry.cms.hhs.gov by provider name, location, or specialty.1CMS. NPPES NPI Registry
- The provider’s Federal Tax ID (EIN). The insurer uses it to process payments and handle tax reporting. The billing office can supply it.
If you’re unsure about any detail, call the billing office before you submit. A quick confirmation is faster than fixing a rejected form.
Where to Send the Completed Form
The form goes to your workers’ compensation insurer’s claims office, not to the Department of Industrial Accidents. Look at the insurer’s correspondence for the claims-handling address or fax number. Certified mail gives you a delivery receipt, which matters later if you need to prove when the insurer was notified.
If you also need to file something with the DIA, the mailing address is:
Department of Industrial Accidents
Dept. 110
Lafayette City Center
2 Avenue de Lafayette
Boston, MA 02111-17502Mass.gov. File a Claim
Injured workers handling their own claim can mail or hand-deliver forms to the DIA. If you’re represented by an attorney, your lawyer must file through the DIA’s online portal; paper filings from attorneys are not accepted.2Mass.gov. File a Claim Either way, keep a personal copy of whatever you send. That copy becomes important if a billing dispute surfaces months later or if you need documentation for a hearing.
What Happens After You Submit
Once the insurer processes the form, you should receive a date-stamped acknowledgment confirming the provider on file. If nothing arrives within a couple of weeks, follow up with the claims adjuster directly. File the receipt somewhere accessible, since it proves you met the notification requirement.
From that point, treatment from your designated provider gets routed through the correct billing channel. If there’s a delay in processing, any treatment you receive in the interim should still be covered as long as you can show the form was submitted before the treatment date.
Who You Can Name on the Form
Massachusetts workers’ compensation law gives you broad control over who treats your injury, with one narrow limit. If your employer’s insurer has a preferred provider arrangement, your very first appointment may need to be with a doctor inside that network. After that first visit, you can pick any licensed provider you want, regardless of whether they participate in the insurer’s plan.3General Court of Massachusetts. Massachusetts General Laws Part I, Title XXI, Chapter 152, Section 30
You also get one chance to switch your treating provider without needing the insurer’s permission. The same one-time switch applies within a specialty: if your treating doctor refers you to an orthopedic surgeon and you’re unhappy with that surgeon, you can switch to a different orthopedic surgeon once.3General Court of Massachusetts. Massachusetts General Laws Part I, Title XXI, Chapter 152, Section 30 Each time you select or switch a provider, the insurer needs formal notice, which is what this form provides.
If a preferred provider arrangement applies, the insurer must give you a list of in-network providers organized by specialty and geographic area. That list should be posted at your worksite and handed to you after a reported injury.4Cornell Law Institute. 452 CMR 6.03 – Preferred Provider Arrangements Under Workers Compensation
What Your Provider Is Expected to Do
Naming a treating physician on the form puts a reporting obligation on that provider. They must send medical reports about your injury to you, the insurer, and the DIA within fourteen days of each examination. A provider who misses that deadline faces a civil fine of between $25 and $1,000 per violation, with escalating penalties for repeat failures.5General Court of Massachusetts. Massachusetts General Laws Chapter 152, Section 30A
Those reports are the medical evidence that determines whether your benefits continue, whether a specific treatment gets approved, and whether you’re considered able to return to work. A vague or late report can stall your claim, so it’s worth confirming with your doctor’s office that they understand the workers’ compensation reporting timeline.
Be Careful With Broad Medical Releases
Filing the Confirmation of Provider Form does not waive privacy over your entire medical history. Under federal law, your provider can share protected health information with the workers’ compensation insurer, but only to the extent necessary to comply with the workers’ compensation program, and no separate signed authorization from you is required for those disclosures.6eCFR. 45 CFR 164.512 The information shared should be limited to what’s relevant to your injury and claim.
Access to records beyond that, such as unrelated mental health treatment or prior conditions, typically requires your written authorization. Think twice before signing a blanket medical release. A broad release can hand the insurer records that have nothing to do with your claim and that could be used to argue your condition is pre-existing rather than work-related.
