Medians are across issuers with at least 1,000 in-network claims received in the same file (North Carolina: 7 issuers; national: 158 issuers in 32 states). Plan year 2026 file, 2024 claims.
- Reporting lag: the CMS public-use file for a plan year reports claims from two plan years earlier (the PY2026 file carries 2024 claims). These are not this year's figures.
- In-network only: the denial rate is in-network claims denied divided by in-network claims received. Out-of-network claims are shown separately where the issuer reported them.
- "Denied" is broad: CMS counts every denial, including administrative denials, duplicate submissions, ineligibility, incorrect billing and partial denials, not only medical-necessity decisions.
- Issuer level: CMS reports the counts once per issuer per state and repeats them on every plan row; plan-level counts, where present, list denials only, so no per-plan rate is computed.
- Coverage: only issuers on the federally facilitated marketplace (HealthCare.gov states) report to this file. Employer plans, Medicare and Medicaid are not included.
- No inference of intent: a higher rate can reflect the issuer's mix of claims, its billing rules or its membership as much as its coverage decisions. Compare with the state median and read the N.

Questions
What counts as a "denied" claim in UnitedHealthcare of North Carolina, Inc's 21.2% rate?
Every in-network claim the issuer reported as denied in the 2024 claims year, including administrative denials, duplicates, ineligibility, incorrect billing and partial denials, not only medical-necessity decisions. The figure is in-network claims denied divided by in-network claims received, exactly as reported to CMS.
Why is the data from 2024 when the file is for plan year 2026?
CMS's Transparency in Coverage public use file for a plan year reports claims data from two plan years earlier. This is the most recent issuer-level denial data CMS publishes for marketplace plans.
Does this predict whether my UnitedHealthcare of North Carolina, Inc claim will be denied?
No. It is an aggregate across all of the issuer's marketplace plans in North Carolina. Your own claim depends on your plan, the service and the documentation. Compare the rate with the North Carolina median (21.5%) and read the N before drawing conclusions.
How do I appeal a UnitedHealthcare of North Carolina, Inc denial?
Read the denial letter for the reason and the deadline, request the criteria and the claim file in writing, and file an internal appeal (at least 180 days on marketplace plans under 45 CFR 147.136). In the reporting year, 37.4% of internal appeals to this issuer were overturned (526 of 1,407). If the internal appeal fails, independent external review is available.
