Suppose I want to work on patients with heart failure, which has a broader ICD code of I50, but in order to separate that patient, we have to add all the subcodes separately. Is there any way to include all the I50x subcodes?

Use this bootstrapping substr command as below in order to modify per your variable change variable name and ICD code make sure the ICD code is upper case
{
gen acutestroke_new = 0 forvalues i = 1/40
replace acutestroke_new = 1 if substr(i10_dx`i', 1, 3) == "I63"
}
