MEMORANDUM

Nevada state prisoner Dante Hanalei Pattison appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1983 action alleging retaliation and deliberate indifference to his serious medical needs. We have jurisdiction under 28 U.S.C. § 1291 . We review de novo the district court’s decision on cross-motions for summary judgment. Guatay Christian Fellowship v. County of San Diego, 670 F.3d 957, 970 (9th Cir. 2011). We affirm.

The district court properly granted summary judgment for defendants on Patti-son’s retaliation claim because Pattison failed to raise a genuine dispute of material fact as to whether defendants retaliated against him because of his earlier lawsuit. See Rhodes v. Robinson, 408 F.3d 559, 567-68 (9th Cir. 2005) (setting forth elements of a retaliation claim in the prison context).

The district court properly granted summary judgment for defendants on Patti-son’s deliberate indifference claim because Pattison failed to raise a genuine dispute of material fact as to whether defendants were deliberately indifferent to his serious medical needs. See Toguchi v. Chung, 391 F.3d 1051, 1057 (9th Cir. 2004) (a prison official acts with deliberate indifference only if he or she knows of and disregards an excessive risk to the prisoner’s health); Jackson v. McIntosh, 90 F.3d 330, 332 (9th Cir. 1996) (difference in opinion between the physician and the prisoner regarding the appropriate course of treatment does not amount to deliberate indifference).

We do not consider matters not specifically and distinctly raised and argued in the opening brief, including discovery and case management issues. See Padgett v. Wright, 587 F.3d 983 , 985 n.2 (9th Cir. 2009).

We reject as unsupported by the record Pattison’s contention that the district court was biased against him.

AFFIRMED.
