Question

The modifier that indicates multiple procedures is:

a. -22

b. -26

c. -32

d. -51

Answer 1

The modifier indicating multiple procedures is -51, an object moving downward in physics convention gets a negative sign (-), and if I1 = 5 A and I3 = -2 A, then I2 would be (b) -3 A.

Step-by-step explanation:

The modifier that indicates multiple procedures is denoted by the code -51. This modifier is used in medical billing and coding to indicate that multiple procedures were performed during the same operative session.

For the physics-related part of the question, by convention, an object moving downward is assigned a negative sign (-). This is a reflection of the directional convention where up is positive and down is negative in a Cartesian coordinate system. So the correct answer is b. A negative sign (-).

Regarding the electric circuit component, in order to calculate the current I2, if I1 = 5 A and I3 = -2 A, and knowing that the sum of currents at a junction must equal zero (Kirchhoff's current law), I2 must be -3 A, which is calculated by subtracting I3 from I1 (5 A - (-2 A) = 7 A, then applying the negative sign because the current is moving in the opposite direction to I1.) Hence, the correct answer is b. -3 A.
