Appeal Success Likelihood Estimator

Estimates the probability that an insurance claim appeal will succeed based on denial reason, documentation strength, policy tenure, and supporting evidence.

Primary Denial Reason

Medical necessity not established Experimental / investigational treatment Coding / billing error Missing or incomplete documentation Out-of-network provider Pre-existing condition exclusion Prior authorization not obtained Policy exclusion (explicit) Coordination of benefits dispute

Documentation Quality

Poor – minimal supporting records Fair – some supporting records Good – complete medical records Excellent – records + physician letter + peer-reviewed evidence

Policy Tenure (years)

Appeal Level

Level 1 – Internal appeal Level 2 – Second internal review Level 3 – External independent review Level 4 – State insurance commissioner / litigation

Treating Physician Support

No physician letter Physician letter provided Physician letter + specialist consultation

Prior Successful Appeals with This Insurer

None 1 prior success 2+ prior successes

Claim Amount ($)

State External Review Mandate

No strong mandate State has strong external review law

#### Formula

Praw = Bdenial × Fdoc × Flevel × Fphysician × Fprior × Ftenure × Fstate × Fclaim

Pfinal = Praw / (1 + Praw)    (logistic compression, clamped to [0.05, 0.92])

Expected Recovery = Pfinal × Claim Amount
