short_code argument to expand_range doesn't work for ICD10

I installed the latest CRAN package. R version 3.5.0

"C81" and "C96" are both valid short and decimal codes. The "short_code" parameter refers to the input, not the output. So what you observe is the expected behavior.

If you want the range to return decimal codes use short_to_decimal:

> short_to_decimal(expand_range("C81", "C81"))
