Under Reg 193, a New York Medicare supplement applicant's prior creditable coverage reduces the preexisting-condition exclusion unless the coverage was interrupted by a break longer than:

Why C is correct

Under Reg 193 (11 NYCRR Part 58), creditable coverage from earlier health insurance counts against the Medigap preexisting-condition exclusion so long as it was uninterrupted, and a break of up to 63 days is tolerated before earlier coverage stops counting. The measuring stick is the gap in coverage, not the total time insured, and the 6-month exclusion ceiling still caps whatever waiting period remains.

Why the other options are wrong

• A) Thirty days is shorter than the tolerance the regulation allows; a break of that size does not wipe out earlier creditable coverage.
• B) Ninety days overstates the grace the rule gives; the cutoff arrives earlier than that.
• D) Six months is the maximum preexisting-condition exclusion itself, not the permissible break in prior coverage.

Memory hook

63 days - just over two months - keeps the creditable clock running.
