4. Account Debtors on Health-Care-Insurance Receivables. Subsection (d) [Maine cite subsection (4)] also is new. It provides that this section does not apply to an assignment of a heath-care-insurance receivable. The obligation of an insurer with respect to a health-care-insurance receivable is governed by other law.

(i)__Only a portion of the account, chattel paper or general intangible has been assigned to that assignee;

(ii)__A portion has been assigned to another assignee; or
