Before LOKEN, BYE, and COLLOTON, Circuit Judges.
                           ___________

PER CURIAM.
       Inmate David Ferrell appeals following the district court’s1 adverse grant of
summary judgment in his 42 U.S.C. § 1983 action. To the extent he has not waived
his claims against the Arkansas Department of Correction (ADC) defendants by
failing to address those claims on appeal with any specificity, see Meyers v. Starke,
420 F.3d 738, 743 (8th Cir. 2005), we agree with the court that Ferrell failed to offer
evidence that he administratively exhausted the claims, see King v. Iowa Dep’t of
Corr., 598 F.3d 1051, 1052-53 & n.2 (8th Cir.) (reviewing de novo district court’s
interpretation of Prison Litigation Reform Act’s administrative exhaustion provision;
inmate must complete administrative review in accordance with applicable rules
before bringing suit in federal court), cert. denied, 131 S. Ct. 499 (2010).

       As to the Correctional Medical Services (CMS) defendants, we agree with the
district court that those claims are based on Ferrell’s unsupported disagreement with
medical treatment decisions, and that he did not adequately counter the CMS
defendants’ evidence as to the appropriate treatment for his Hepatitis C and inguinal
hernia. See Mason v. Corr. Med. Servs. Inc., 559 F.3d 880, 884-85 (8th Cir. 2009)
(summary judgment standard of review); Meuir v. Greene County Jail Employees, 487
F.3d 1115, 1118-19 (8th Cir. 2007) (mere difference of opinion over matters of expert
medical judgment or course of treatment does not amount to constitutional violation);
see also Bloom v. Metro Heart Group of St. Louis, Inc., 440 F.3d 1025, 1028-29 (8th
Cir. 2006) (speculation and conjecture are insufficient to defeat summary judgment).2
The district court is affirmed.
                         ______________________________


      1
        The Honorable Brian S. Miller, United States District Judge for the Eastern
District of Arkansas, adopting the report and recommendations of the Honorable Beth
Deere, United States Magistrate Judge for the Eastern District of Arkansas.
      2
       Contrary to Ferrell’s assertions, he cannot base a 42 U.S.C. § 1983 claim on
alleged violations of workers’ compensation laws or breach of contract. See C.N. v.
Willmar Pub. Sch., Indep. Sch. Dist. No. 347, 591 F.3d 624, 633 n.10 (8th Cir. 2010).
