How Does Health Insurance Portability Work? 
The idea behind portability is as follows : If a person has carried coverage -LRB- been insured -RRB- prior to starting with another health plan elsewhere , they should not be punished by having a pre-existing condition schedule applied to them as they have no gap in coverage . The idea behind Portability is wing walking , moving from one wing to the other without falling off of either plane . When you apply for coverage , the new provider will ask for a certificate of prior coverage . They will use that as proof and waive any pre-existing condition clauses on the new policy .
