UnitedHealthcare: timely filing limit
Initial claim
No published default
Timely filing limits vary by contract. We could not confirm a single default limit that applies across every UnitedHealthcare contract, so we are not going to state one. Check your own participation agreement, or the payer portal, before relying on a number for this deadline.

Appeal window
No published default appeal window. Check the payer's own appeals policy.
Caveats
UnitedHealthcare sets timely filing in the specific participation agreement, which differs by commercial, Medicare Advantage, and community/state Medicaid product and by state. A direct fetch of UHC's own reimbursement policy page could not be completed during this research; verify against the applicable UHC provider manual or contract before relying on any single figure.
