Development
On January 10, 2011, ABC renewed Private Practice for a fifth season. The fifth season premiered on September 29, 2011.

A plot device this season sees most episodes begin with Addison at a therapist's office introducing the episode while most but not all end with a redux of the plot device although Kate Walsh does not narrate the actual episodes. In the beginning of the season a major part of the story-line is Amelia's drug addiction, and how all of the doctors work to try to save her. Another story-line in the beginning of the season is the practice going under, and trying to save it and Violet trying to get her medical license back. A major story-line that has been in place since the fourth season, is Addison trying to have a baby with IVF treatments, but after the IVF treatments fail and she no longer has any eggs left, she decides to adopt a baby, eventually adopting a baby named Henry, who she delivered the very same day she was called about adopting him. A plot that took place for the entire season, is Cooper finding out that he has a son and that the mother, Erica Warner, has an inoperable brain tumor, and how Cooper and Charlotte must deal with the death of Erica and how it affects Mason. Through the middle of the season, Pete and Violet decide that they should go through separation; Violet tries to move on with a relationship with Scott, a paramedic she met, but the relationship eventually ends when Scott ends it and Violet decides to try to work things out with Pete. The addition of a new character, Jake Reilly, opened up the story-line of Addison trying to figure out if she wants to pursue a relationship with Sam or with Jake. After Amelias' drug addiction story-line, it's found out that Amelia is pregnant, and she has to deal with finding out that her baby (who was conceived while Amelia was actively using drugs) was developing without a brain and would not survive; she decides to carry it to term to donate the organs. Amelia also dealt with her anger at Addison while having Jake be her doctor.
