Do diagnosis codes have modifiers?

Diagnosis coding always requires the most specific code possible. It may not be necessary to include a modifier if the description is contained in the ICD-10 coding.

What are ICD 10 essential modifiers?

Essential modifiers appear next to a lead term or as subterms indented below lead terms in the alphabetical index and do affect the selection of target code. They describe essential differences in site, etiology or type of disorder and must appear in the clinical statement for the code to be assigned.
