What the Claims Allege

Litigation has concerned the use of automated tools to determine how long patients require post-acute care such as skilled nursing or rehabilitation, with allegations that coverage was cut off according to algorithmic predictions rather than individual clinical assessment.

The specific allegation is that treating clinicians recommended continued care and coverage was terminated anyway, leaving patients to leave facilities prematurely or pay privately.

A denial is not the end of the process

Most people accept a first denial. Internal appeals overturn a meaningful share of them, and external review by an independent body overturns more. The appeal process is where denials are actually reversed, and it is underused.

For employer-sponsored plans, ERISA governs and significantly restricts remedies. It generally allows recovery of the benefit wrongly denied but not consequential or punitive damages, and requires administrative appeals to be exhausted before suit.

Medicare Advantage plans operate under federal programme rules with their own appeal structure, including expedited appeals where a discharge is imminent, which is the relevant route in post-acute care disputes.

Claims also plead bad faith and consumer protection violations where state law applies, though ERISA preemption removes those theories for most employer plan members.

How to Challenge a Denial

Request the denial in writing with the specific clinical criteria applied, and ask for the complete claim file, which plans must provide on request under ERISA and which frequently reveals the basis for the decision.

Ask the treating clinician to provide a letter addressing the stated criteria directly rather than a general statement of need, since appeals succeed most often where they engage with the precise ground of denial.

✅

External review is independent of the insurer

After internal appeals, most plans are subject to external review by an independent body whose decision binds the insurer. It is free to the patient in most cases and overturns a significant proportion of denials.
