Quick overview

Changing jobs can create a narrow window to compare plans, maintain existing care, and avoid surprise bills. This guide walks through practical steps, common tradeoffs, and real-world tactics I use when advising clients to keep care continuous and costs under control.

Why this matters

A plan that looks cheaper on paper can be more expensive over a year if it has a narrow network, weak prescription coverage, or a high out-of-pocket maximum. In my practice advising employees and small-business owners, I’ve seen good decisions save thousands and poor choices cause costly disruptions—especially for people with ongoing specialist care or prescription needs.

Step-by-step: How to evaluate new employer coverage

  1. Confirm timing and effective dates
  • Ask HR when your new coverage starts and when prior coverage ends. Employers commonly make coverage effective the first of the month after hire, but smaller employers may offer immediate or delayed start dates.
  • If your previous coverage ends before the new plan begins, you may have options: COBRA continuation, short-term plans (with limits), or a Special Enrollment Period to buy Marketplace coverage (usually within 60 days of losing prior coverage) (Healthcare.gov).
  1. Compare total expected annual cost, not just premiums
  • Total cost = premiums + expected out-of-pocket spending (deductible, co-insurance, co-pays) + prescriptions. Use your past year’s claims as a baseline.
  • Many employers provide a cost estimator or example scenarios. Use those tools and run your own scenario for planned care (pregnancy, surgeries, therapy) and chronic care.
  1. Check provider networks and continuity of care
  • Confirm that your primary care doctor, specialists, and preferred hospitals are in-network. If you require ongoing treatment, ask HR whether the plan offers transitional or continuity-of-care provisions.
  • If a key provider is out-of-network, estimate the difference in cost and discuss alternatives with your provider.
  1. Review prescription drug coverage
  • Compare formularies and tiers. A plan with a slightly higher premium may dramatically lower your cost if it covers preferred medicines at a better tier or with a lower deductible for drugs.
  1. Understand benefit limits and covered services
  • Check coverage for maternity, mental health, physical therapy, and durable medical equipment. Some plans limit visits or require prior authorization for high-cost services.
  1. Evaluate tax-advantaged accounts and cost-sharing structures
  • HDHP + HSA combos reduce taxable income and build a health savings buffer, but high deductibles can be risky if you need expensive care soon after your transition.
  • FSAs can be useful, but recall that dependent care FSAs and healthcare FSAs have different rules; unused funds may be forfeited at plan year end.
  1. Consider continuity options: COBRA, Marketplace, or short-term plans
  • COBRA allows you to keep your old employer plan for a limited time (generally up to 18 months for most qualifying events). COBRA coverage can be costly because you pay the full premium plus up to a 2% administrative fee. For details, see FinHelp’s COBRA overview and Healthcare.gov resources.
  • If you’re eligible for a Special Enrollment Period, you can enroll in a Marketplace plan (Healthcare.gov) within 60 days of losing prior coverage. Marketplace plans may offer premium tax credits if your household qualifies.
  • Short-term plans can bridge a gap but often exclude pre-existing conditions and essential benefits required by ACA-compliant plans.

Practical scenarios and tradeoffs

  • Someone with frequent specialist visits: prioritize network access and lower co-pays over the lowest premium. A plan with slightly higher premiums but a larger network or lower specialist co-pay will usually cost less overall.

  • Someone with predictable prescriptions: map your drugs to each plan’s formulary. A different prescription tier can change monthly costs drastically.

  • Someone expecting major care (e.g., planned surgery or maternity): choose lower out-of-pocket maximums and verify prior authorization rules.

Real example from my advising: a client switched jobs and saw a $300 annual premium reduction but the new plan’s specialty co-pay and out-of-pocket max were higher. After modeling expected visits and prescriptions, the slightly higher-premium old plan was still the cheaper option across the year.

Checklist to use before you accept or start a new job

  • Ask HR: enrollment window, effective date, and whether benefits are grandfathered.
  • Get plan summaries: Summary of Benefits and Coverage (SBC) for each option.
  • List your providers and check network status online or with HR.
  • Run cost scenarios for usual care and an acute-care event.
  • Compare prescription formularies and pharmacy networks.
  • Confirm HSA/FSA options and employer contributions.
  • Decide on COBRA or Marketplace if there’s a gap; apply early.

How COBRA, Marketplace, and short-term plans compare

  • COBRA: Keeps your exact employer plan for a limited time. It preserves network and coverage rules but can be expensive because you pay the full employer and employee share plus an administrative fee (up to 2%). See FinHelp’s COBRA article for specifics: What is COBRA continuation coverage?

  • Marketplace (Healthcare.gov): May offer lower premiums and subsidies if you qualify. You have 60 days after losing prior coverage to enroll in a Marketplace plan (Special Enrollment Period) (Healthcare.gov).

  • Short-term plans: Typically less expensive but do not meet ACA requirements for essential health benefits and may exclude pre-existing conditions and many services.

Common mistakes to avoid

  • Choosing based only on lower premiums without modeling out-of-pocket costs.
  • Missing the enrollment window and assuming you can retroactively enroll.
  • Assuming a provider will accept coverage—always verify network status.
  • Overlooking prescription formularies and specialty drugs.
  • Forgetting to port HSA funds or understand employer HSA contributions and plan compatibility.

Professional tips I use with clients

  • Run a 12-month cost simulation: premiums + expected visits + prescriptions + one unpredictable event (emergency or specialist referral).
  • Ask HR about transitional care or grandfathering existing authorizations for ongoing treatments.
  • If you need time to compare options, consider COBRA as a bridge while you finalize a choice—compare the annualized cost to a Marketplace plan before committing.
  • Use a licensed broker for complex cases (multiple dependents, rare conditions). Brokers can provide plan comparisons and clarify networks.

Short FAQs

  • How long do I have to enroll in a new employer’s plan? Employers typically set an initial enrollment window (commonly 30 days, sometimes 60) from your hire date. Confirm with HR.

  • Can I keep my old plan after I leave? You may be able to keep the same plan temporarily through COBRA. See the FinHelp COBRA guide for details.

  • What if my specialist isn’t in-network? Ask about continuity-of-care options, negotiate a cash price with the provider, or consider switching to an in-network specialist if feasible.

Final notes and professional disclaimer

Choosing the right health insurance when changing jobs is part math, part planning, and part timing. Treat it like a short-term project: gather documents, run simple cost models, and check networks before the effective date. In my experience, a focused 1–2 hour review yields decisions that reduce unexpected costs and preserve care continuity.
