A new derivation of a general expression for the Coddington equation for any plane of incidence is obtained from two particular cases, for the sagittal and the tangential Coddington equations. Although this generalized expression has been already obtained by Conrady from a general treatment of the optical path difference for skew parabasal rays, we propose a simpler derivation for a general Coddington's equation that includes skew rays not necessarily in the tangential or sagittal planes.
