Instructional Notations
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
- underlying disease, such as:
- amyloidosis E85
- congenital early syphilis A50.0
- echinococcosis B67.0 B67.9
- malaria B50.0 B54
- schistosomiasis [bilharziasis] B65.0 B65.9
- vitamin C deficiency E54
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- rupture of spleen due to Plasmodium vivax malaria B51.0
- splenitis, splenomegaly in late syphilis A52.79
- splenitis, splenomegaly in tuberculosis A18.85
