The Patisambhidamagga has been described as an "attempt to systematize the Abhidhamma" and thus as a possible precursor to the Visuddhimagga. The text's systematic approach and the presence of a matika summarizing the contents of the first section are both features suggestive of the Abhidhamma, but it also includes some features of the Sutta Pitaka, including repeated invocation of the standard sutta opening "evaṃ me suttaṃ" ('thus have I heard'). Its content and aspects of its composition overlap significantly with the Vibhanga, and A.K. Warder suggested that at some stage in its development it may have been classified as an Abhidhamma text.
