I37 vs Q22.1
I37 (Nonrheumatic pulmonary valve disorders) compared with Q22.1 (Congenital pulmonary valve stenosis), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. I37 carries an Excludes1 note covering Q22.1: “pulmonary valve disorder specified as congenital (Q22.1, Q22.2, Q22.3)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
