About R13

R13 is the ICD-10-CM diagnosis code for Aphagia and dysphagia. It belongs to block R10-R19 (symptoms and signs involving the digestive system and abdomen) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: R13.0 (Aphagia) and R13.1 (dysphagia).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
