P. v. United Healthcare Insurance, 564 F.Supp.3d 1100

Plaintiff David P. (plan participant) sought ERISA benefits under the Morgan Stanley Medical Plan for his daughter L.P.’s residential treatment at Summit Achievement (11/28/2016–2/13/2017) and Uinta Academy (2/14/2017–11/30/2017).
United/United Behavioral Health (UBH) administered mental-health and substance-abuse claims under the Plan and had discretionary authority to interpret plan terms and decide claims.
UBH denied coverage for L.P.’s entire Summit stay and authorized only the first eight days at Uinta, denying the remainder; Plaintiffs paid over $177,000 out-of-pocket and exhausted internal appeals and external reviewers (who affirmed UBH).
UBH’s denial letters relied on lack of medical necessity for RTC care, cited improvements and suitability of less intensive care, and provided largely conclusory rationales without record citations.
Plaintiffs argued UBH failed to consider L.P.’s substance use disorder, ignored treating providers’ recommendations, and committed procedural ERISA violations; the court found serious procedural defects and also held UBH’s substantive denials were unreasonable.
Remedy: District court reversed UBH, ordered payment for Summit and Uinta care, awarded prejudgment interest, and granted Plaintiffs’ request to seek attorneys’ fees and costs (submit petition within 21 days).

Issue	Plaintiff's Argument	Defendant's Argument	Held
Proper standard of review for UBH’s denials	De novo review because of procedural irregularities in the administrative process	Arbitrary-and-capricious (deferential) review because Plan grants UBH discretionary authority	Court found serious procedural defects warranting de novo review, but ruled UBH’s decision fails even arbitrary-and-capricious review
Whether UBH considered substance use disorder as independent basis for RTC care	UBH ignored L.P.’s documented substance use disorder and failed to analyze medical necessity for SUD treatment	UBH relied on mental-health-focused grounds and external reviewers’ affirmations	UBH failed to address SUD; denial arbitrary and capricious for not considering an independent ground for benefits
Treatment of treating providers’ opinions	Treating clinicians recommended residential care; UBH ignored or failed to meaningfully engage these opinions	No special deference owed to treating providers; UBH contends it reasonably evaluated the record	Court held UBH abused discretion by not fairly engaging or explaining why it rejected treating providers’ opinions
Remedy: remand vs award of benefits; prejudgment interest and fees	Plaintiffs seek award of benefits, prejudgment interest, and attorneys’ fees	Defendants request remand for further review if reversal occurs	Court awarded benefits for the covered RTC stays, prejudgment interest, and discretionary attorneys’ fees; remand denied as inappropriate
