Chapter 22 guidelines
Codes for special purposes
U00-U85
A newer chapter reserved for codes for special purposes, including provisional codes created for emerging public health needs (such as codes introduced during the COVID-19 pandemic).
Key coding points
- •Codes in this chapter are typically added outside the normal annual cycle to respond quickly to emerging conditions, so check for mid-year addenda when a very recent diagnosis doesn't appear in the standard annual release.
