Sec. 220.103  Two or more unrelated impairments--initial claims.

    (a) Unrelated severe impairments. Two or more unrelated severe 
impairments cannot be combined to meet the 12-month duration test. If 
the claimant has a severe impairment(s) and then develops another 
unrelated severe impairment(s) but neither one is expected to last for 
12 months, he or she cannot be found disabled even though the 2 
impairments in combination last for 12 months.
    (b) Concurrent impairments. If the claimant has 2 or more concurrent 
impairments which, when considered in combination, are severe, the board 
must also determine whether the combined effect of the impairments can 
be expected to continue to be severe for 12 months. If 1 or more of the 
claimant's impairments improves or is expected to improve within 12 
months, so that the combined effect of the claimant's impairments is no 
longer severe, he or she will be found to not meet the 12-month duration 
test.
