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.

When would a testcross be done?
vova2212 [387]
<span>Additional facts:
A test cross between an organism whose genotype for a certain trait is unknown and an organism that is homozygous recessive for that trait so the unknown genotype can be determined from that of the offspring.
Answer:
You'd use it when you wish to see if the one that you think is a homozygous dominant is a purebred, because if you did get a recessive offspring then it proves that the animal is a heterozygous and not a purebred.</span>
