Embodiments herein relate to polyacrylic acid containing lubricious coatings for medical devices. In an embodiment, a lubricious coated medical device is included having a substrate and a first layer disposed over the substrate. The first layer can include a photoreactive polyvinylpyrrolidone, a non-photoreactive polyvinylpyrrolidone, and a crosslinking compound. A second layer can be disposed over the first layer, the second layer can include a poly(acrylic acid), and a non-photoreactive polyvinylpyrrolidone. The non-photoreactive polyvinylpyrrolidone of the second layer forms a complex with the poly(acrylic acid) of the second layer. The non-photoreactive polyvinylpyrrolidone of the second layer has a concentration existing as a gradient through a thickness of the second layer with a lower concentration at an outer surface of the second layer than at an inner surface of the second layer. Other embodiments are also included herein.
