Kindred Healthcare will split with pharmacy partner PharMerica and join forces with Omnicare at the end of 2013, according to documents filed with the Securities and Exchange Commission.

Form 8-K documents filed June 21 confirmed that Kindred does not plan to renew its PharMerica contract for skilled nursing services after it lapses Dec. 31. Under a separate contract, PharMerica will continue to provide pharmacy management for Kindred hospitals through 2014.

Kindred’s nursing facilities accounted for 11.5% of PharMerica’s revenue in 2012, according to the pharmacy’s annual report. Upon news of the contract loss, PharMerica share prices slid, and a Bank of America analyst lowered the price target on the company from $18 to $17.

This is another setback for PharMerica, which lost other major contracts when Golden Living created pharmaceutical services company AlixaRx last fall.
