Tabular List NotesGuidance
Coding notes and annotation back-references applicable to this code.
Code First
- underlying disease, such as:
- disease of blood and blood-forming organs, unspecified D75.9
- other hemoglobinopathies D58.2
- thalassemia D56
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.
