Do methadone and hydrocodone show up the same on a urine drug screen?

Yes, a general drug test would indicate that they are both opiates, witch is a group of drugs that include most painkillers. But I believe that depending on the reason for the test, is it for employment or probation? more specific tests may be used in certain cases in which the specific drug can be identified. This is being done more and more in just regular DR. offices now. Anyway hope this helped and good luck.
