-nemia

DEFINITION of -nemia

In medical terminology, -emia / -aemia is a combining suffix used to form nouns that describe pathological or quantitative conditions of the blood, such as deficiency, excess, or abnormal presence of cells, substances, or organisms. Examples include anemia (reduced RBCs/hemoglobin), bacteremia (bacteria in the blood), and hyperlipidemia (elevated lipids in the blood).

ETYMOLOGY of -nemia

latin - From Neo-Latin -emia, based on Greek compound stem -aimia −αιμιˊα−αιμιˊα, from haima (αἷμα)(αἷμα) meaning “blood.”

• British spelling often shows up as -aemia (e.g., anaemia, leukaemia); American spelling simplifies to -emia (anemia, leukemia).

RELATED TERMS to -nemia

• Aliases / spelling variants:

  • -emia (American)

  • -aemia (British; often seen in older literature)

• Closely related roots/prefixes:

  • hem- / haem- /hemat- / haemat- = blood (e.g., hemoglobin, hematology), often paired with -emia in blood-condition terms.

• Conceptually related suffixes:

  • -penia = deficiency, too few (e.g., leukopenia), sometimes used with blood cell lines rather than -emia.​

  • -osis = condition, often abnormal (e.g., leukocytosis), frequently used for increased counts where -emia might also appear.

Coding angle (how you’ll see it in ICD-10-CM / CPT)

The suffix itself doesn’t have standalone codes, but you’ll see it in many diagnosis names. Common -emia diagnoses (just to anchor it in your coder brain; verify specifics in your encoder/ICD-10-CM book when assigning):

• Anemia (various types, e.g., iron deficiency, B12 deficiency, aplastic)​

• Thalassemia

• Hyperlipidemia

• Hyperglycemia / hypoglycemia

• Bacteremia

Each of these conditions will have its own ICD-10-CM code(s); -emia just tells you “this word is describing a blood condition,” so it’s a quick mental flag that you’re in the heme/metabolic space.
