Mammogram not elsewhere classified
What does code610 mean in medical terms
Electrolyte and fluid disorders, not elsewhere classified
It means "rehabilitation procedure not elsewhere classified"
In the ICD-10 (International Classification of Diseases, 10th Edition) coding manual, "in CCE" means "in conditions classified elsewhere." For example, the diagnostic code 293.84 is a diagnostic code for "Anxiety Disorder in Conditions Classified Elsewhere." I believe the person making the diagnosis is supposed to specify the condition (general medical condition) causing the anxiety disorder by listing, for example, "Anxiety Disorder in Hyperthyroidism" (or whatever the general medical condition is).
In medical terms, stool means feces.
Inspiration in medical terms means inhaling.
Occult means hidden in medical terms.
Progressive medical terms means it will get worse.
In medical terms, "sinister" means left.
