  • Walking welfare plan administrators through various HIPAA portability, COBRA, and ACA dilemmas in order to find workable solutions, for example:
  • HIPAA portability: preparing special enrollment notices and instructing plan administrators on rules for proper notice distribution;
  • COBRA: consulting with small businesses over group health plan continuation coverage responsibilities and potential exemptions; and
  • ACA: advising large employers on proper methods of counting full-time employees to assess employer shared responsibility compliance;
  • Correcting plan errors for tax and fiduciary compliance; and
  • Analyzing service provider contracts.
