The correct answer is 97761 * 2, L6050, Z44.8, Z89.11.
In the CPT index when one looks for Prosthetics/Training, then one is directed towards 97761. The code is repeated for every 15 minutes. As 30 minutes are spent in training, so 2 units are reported. In the HCPCS level II codebook when one looks for Disarticulation/Wrist prosthesis, one is directed towards codes L6050, L6055. On the basis of description, the prosthesis is reported with code L6050.
In the alphabetic index of ICD-10-CM, when one looks for fitting/device NOS/prosthetic (external), then one is directed towards the code Z44.8. In the index when one looks for the absence of organ or part (complete or partial)/wrist and hand (acquired) then one is referred towards the code Z89.11.
Take for example - you touching something sharp and instantly moving your hand away.
Sensory neurons in your fingers detect the external stimuli of the sharp object and send a nerve impulse to the spinal cord (does not reach brain) and is sent back to a motor neurone - attached to an effector that moves the muscle and moves the hand away. This is a rapid reflex action and involuntary.
