Or calculate the spread between 2 interest rates, a and b, by using the formula a - b. Use the assigned data series variables (a, b, c, etc.) together with operators (+, -, *, /, ^, etc.), parentheses {(,)}, and constants (1, 1.5, 2, etc.) to create your own formula (e.g., 1/a, a-b, (a+b)/2, (a/(a+b+c))*100).
The ICD code F411 is used to code Generalized anxiety disorder. Generalized anxiety disorder (GAD) is an anxiety disorder characterized by excessive, uncontrollable and often irrational worry, that is, apprehensive expectation about events or activities.
Keep this in mind, as this is still true for ICD-10-CM, for the most part.

The intent of this category, from what I understand, is to include single episodes of major depression.
