What are the Transparency, in Coverage rules. Who do they affect?
The first rules came out in 2020.. Since then, non-grandfathered group health plans and insurers have had to post their prices online in public files. One file shows what they pay in-network providers. Another shows what they allow for out-of-network care. A third shows prescription drug prices. Plans also have to give members cost-sharing information through an online tool, or on paper if a member asks. The 2026 update is meant to make all of that data easier to use.
The rules are for plans and insurers, not for practices. Still, patients and the public are the ones who see the results, since the price data is posted for anyone to read.
What changed in the 2026 final rule?
CMS says the old files were huge, hard to read, and hard to compare with hospital price data. Here is how the update tries to fix that:
- One file per provider network. Plans used to post one file per plan. Now it is one in-network rate file for each provider network, and plans must list the network name and ID.
- Fewer odd rates. Plans must leave out rates for services a provider would not normally be paid for, based on specialty. CMS’s own example is a podiatrist doing heart surgery.
- Two new files. A Taxonomy File explains how the plan decided which rates to leave out. A Utilization File lists the providers who were paid for at least one claim in the most recent plan or policy year.
- Product type. Files must say whether a plan is an HMO, a PPO or another type.
- More out-of-network data. Allowed amount files are now grouped by market type, and the reporting threshold drops from 20 claims to 11.
- Quarterly updates. Plans update the in-network rate and allowed amount files every quarter instead of every month.
- Easier to find. Plans must post a text file that shows where the files are and gives a contact email. They must also add a homepage footer link called “Price Transparency” or “Transparency in Coverage.”
- One file format. CMS plans to name JSON in its technical guidance.
- Attestation. Plans must state that the data is true, accurate and complete, and name the senior official in charge.
- Cost-sharing by phone. Members can now ask for cost-sharing information by phone, not just online or on paper. A plan may limit phone requests, but not below 20 providers per day, and it must tell the caller about the limit.
When do the changes start?
The final rule was published in the Federal Register on October 6 2026. The final rule takes effect on December 7 2026. Different parts start later. The dates below come from the government’s FAQs Part 75 and the CMS fact sheet.
| Date | What starts |
|---|---|
| Dec 7, 2026 | The final rule takes effect. |
| Jan 1, 2027 | Updated cost-sharing rules, including the phone option, apply for plan years (policy years in the individual market) that begin on or after this date. |
| Mar 6, 2027 | New rules for the in-network rate and allowed amount files apply. The first posting is due April 1, 2027, then quarterly. |
| Sep 6, 2027 | Taxonomy File, Text File and Utilization File rules apply. The first Taxonomy File and Text File postings are due October 1, 2027. |
The Utilization File moves on a slower track. Its first posting isn’t due until July 1, 2028, and after that it is posted once a year, according to the government’s FAQs.
What does this mean for your practice?
The rule doesn’t change how you submit claims. Here is what we think it could mean at your front desk and in billing. This is our view, not something the rule says directly.
- Patients may call their plan for cost estimates. The phone option makes cost information easier to get, so your front desk may hear more cost questions before visits.
- Your provider details matter. Plans will use their own provider taxonomies to decide which rates to leave out, and the Utilization File will list paid providers. So it’s smart to confirm that your NPI and specialty are correct in your payer records.
- More public pricing data. Out-of-network amounts will be easier to see, because the claim threshold is lower and the data is grouped by market.
Cost talks with patients often start at the front desk, so solid eligibility checks help. At Shoreline, we think of eligibility as the first step in a good patient cost conversation, and real-time eligibility checks help catch coverage problems before the visit.
MIPS virtual groups: one more date to know
The same CMS newsletter has a reminder for smaller practices. The election period for the 2027 MIPS performance year is open, and it started on October 1, 2026. A virtual group lets solo practitioners and small groups be scored together. According to CMS, solo practitioners and groups with 10 or fewer eligible clinicians can take part. You have to elect before the performance year starts, and you can’t change it once the year begins.
To elect, email MIPS_VirtualGroups@cms.hhs.gov by 11:59 p.m. ET on December 31, 2026 CMS shares the rules and a toolkit on the QPP virtual groups page so look at the page for the eligibility rules before you choose. The bigger payment picture, for 2027 comes from the CMS 2027 Physician Fee Schedule.
What should your practice review now?
- Share these dates with your front desk and billing leads.
- Check that your NPI number and your specialty are correct in your payer records.
- Get your front desk ready for patient cost questions in 2027.
- Decide by December whether a MIPS virtual group makes sense for 2027.
- If you elect a virtual group, email CMS before December 31, 2026.
Final thoughts
This rule is mostly a job for plans and insurers, but patients are the ones who will notice it. Get your team ready for cost questions and keep the MIPS date in view. At Shoreline, we’ll keep following how the rule rolls out and share what matters for practices.
At Shoreline, we support practices with front-end processes and revenue cycle management services, so cost questions and claims stay on track.
