How long has K30 existed?
K30 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with K30?
ICD-10-CM declares these codes mutually exclusive with K30 — exactly one of each pair can be correct for a given encounter.
