United States v. Ahmed, 51 F.4th 12

Abdirashid Ahmed, a certified Somali-English interpreter, conspired with multiple Maine mental-health providers from 2014–2018 to submit inflated or fabricated MaineCare claims for counseling and interpreter services.
Providers submitted claims that reported long sessions (commonly 2.5 hours) though visits were often 10–30 minutes or never occurred; total payments connected to the conspiracy exceeded $1.8 million.
Ahmed pleaded guilty to health-care fraud (superseding indictment count) and the government agreed to dismiss other counts at sentencing; the PSR and parties disputed the attributable loss and a four-level leader/organizer enhancement.
The district court adopted the government’s higher loss figure (about $1.86M), applied the §3B1.1(a) leader/organizer enhancement, produced a Guidelines range of 57–71 months, but imposed a downward variance to 24 months and stated the sentence was "untethered from the Guidelines."
Ahmed appealed, arguing procedural error in Guidelines calculations (loss amount and role enhancement) and substantive unreasonableness (including disparity with Osman’s sentence).
The First Circuit affirmed: any Guidelines miscalculation was harmless because the district court declared the sentence untethered from the Guidelines, and the 24‑month sentence was substantively reasonable.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Role-enhancer (§3B1.1(a)) application	Court erred; Ahmed lacked control over others and was not an organizer/leader	Ahmed was key driver, pressured providers, controlled clients and billing, and supervised Osman	Affirmed: court’s factual findings support leader/organizer enhancement; no clear error
Inclusion of providers’ clinical-billing in loss	Court should exclude amounts billed for providers’ own services as unforeseeable	Providers’ overbilling was foreseeable and within scope of Ahmed’s agreement	Affirmed: providers’ overbilling was within scope and foreseeable; properly included in loss
Credit for legitimate interpreter services against loss	Ahmed should receive offset for interpreter work actually performed	Case was rife with fraud; defendant bore burden to prove legitimacy and failed to do so	Affirmed: district court permissibly used face value start and rejected Ahmed’s insufficient evidence of legitimate services
Substantive reasonableness / sentencing disparity with Osman	Sentence substantively unreasonable and disparate compared to Osman	District court reasonably weighed §3553(a) factors, personal circumstances, and deterrence; Osman not similarly situated	Affirmed: 24 months is a plausible, defensible sentence; disparity not unwarranted given factual differences
