The degree of variation of penis curvature is a continuum, but traditionally 30 degrees is considered the threshold for surgical intervention on chordee. Bowing usually becomes more obvious in an erect penis, but is frequently also palpable when stretching a flaccid penis. Chordee can be congenital or acquired; if the former, it can be associated with Webbed Penis or Hypospadias, which should be coded separately.
