Benefit plan mapping after a merger: lining up two sets of plans side by side.
Before anything is combined, both employers’ plans have to be laid out on one page: carriers, funding, plan designs, eligibility, contributions and renewal dates. That map is what every later decision depends on.
Six elements of a complete plan map.
Carrier and Funding Inventory
List every medical, dental, vision, life, disability and voluntary contract for both employers, with the funding method and renewal date for each.
Plan Design Side by Side
Put deductibles, out-of-pocket maximums, copays and drug tiers in one grid so differences in richness are visible in dollars, not adjectives.
Eligibility Rules Compared
Compare who qualifies, when coverage starts, and how part-time, variable-hour and dependent rules differ between the two groups.
Contribution Strategy Comparison
Show what each employer pays toward employee and dependent coverage, so a later alignment decision starts from actual cost.
Renewal Calendar Overlap
Mark each contract’s renewal and notice deadlines, because the date a contract can be changed often decides the order of integration.
Vendor and System Dependencies
Note the payroll feeds, enrollment platforms and administrators attached to each plan, since those connections shape what can be merged and when.
Plan mapping questions, answered.
Plain answers for HR, finance and deal teams.
Why Map the Plans Before Making Any Decision?
Because the map shows which differences matter. Two plans that look different may cost the same, and two that look alike may sit on different funding or renewal dates.
What Goes Into the Plan Map?
Carriers, funding method, plan designs, eligibility rules, contribution levels, renewal dates, administrators and system connections for every benefit line at both employers.
How Long Does Mapping Take?
Usually a few weeks, depending on how quickly plan documents and renewal files arrive. The first pass is often built from the documents already in hand.
Who Needs to Be Involved?
HR and finance from both sides, the payroll lead, and counsel when plan documents or contracts need interpretation. We run the benefits side of the work.
Do We Need the Plan Documents?
Yes. Carrier summaries are not enough, because the plan document controls eligibility and termination rules. Missing documents are a finding in themselves.
What Happens When One Plan Is Self-Funded?
The map has to include stop-loss terms, claims run-out and administrator contracts, since those affect when and how the plan can end or merge.
Can We Compare Plans Without Merging Anything?
Yes. Mapping is read-only. It tells you what alignment would cost before anyone commits to it.
What If the Two Groups Are Different Sizes?
Size changes the options. A small acquired group may move into a larger plan, while two mid-size groups may keep separate contracts for a period.
Does the Map Show Compliance Issues?
It surfaces them. Differences in eligibility, notices and reporting between the two groups are flagged for counsel to review.
What Do We Receive at the End?
A single reference document showing both programs side by side, with the differences ranked by cost and by difficulty to fix.
