16 Del. Admin. Code § 20000-20930
The State must promptly assess and document the couples' combined countable resources as of the beginning of the first continuous period of institutionalization on or after 9/30/89. The community spouse resource allowance is equal to 1/2 of a couples' combined countable resources as of the beginning of the first continuous period of institutionalization (but not to exceed the maximum permitted). The community spouse resource allowance is a set figure used to determine the amount of resources that will be used to determine institutionalized spouses' initial Medicaid eligibility for the current application period.
If the couple cannot adequately verify what their resources were at the beginning of the first continuous period of institutionalization, the eligibility worker may calculate the community spouse resource allowance based on the resources that can be adequately documented. This may be any point in time between date of admission and date of application. If the couple cannot document their resources, DSS will advise them that it cannot calculate the community spouse resource allowance.
