Each payer has its own denial patterns, appeal process, and preferred channels. These guides are built from our aggregated practice data — anonymized patterns across all Denialbase customers that use the given payer.
Available guides
Kaiser Permanente
Direct integration + overturn patterns. Deep coverage — Kaiser is our first-class payer.
UnitedHealthcare
Common denial types, UHC-specific appeal packet requirements, portal details.

We add payer guides based on customer demand. If you work with a payer that isn’t covered here yet:- Let us know at product@denialbase.com with the payer name and rough volume.
- Share any payer-specific docs (provider manual, appeal packet requirements) you have.
- We typically publish a new guide within 30 days of customer request for payers with meaningful volume.

Methodology
- All data is aggregated and anonymized — no practice-identifiable information ever appears in a published guide.
- Overturn rates are minimums: we report the observed rate only when we have ≥ 50 historical appeals for the payer/denial-type combination.
- Deadlines are payer-policy-derived; we include the exact source (plan docs, regulator bulletin) in the guide.
- Content is refreshed quarterly or when a payer changes their appeal policy.
