Two health plans can look similar on a summary sheet and still cover your prescriptions very differently. One may place a medication on a low-cost generic tier; the other may classify it as a preferred brand, require prior authorization, or exclude it from the formulary altogether. Those differences can matter more to an employee than a modest difference in the monthly premium.
A useful comparison starts with the people who will use the plan—not just the plan’s headline price. Check the doctors and pharmacies employees can use, confirm how each plan covers their medications, and understand eligibility and participation rules before choosing a small-group option. This guide explains how to compare prescription coverage, use a plan comparison checklist, and assess alternatives such as broker shopping or an HRA-style arrangement.
Start with the network, then compare prescription benefits
Before discussing price, ask: Who is in-network for our zip codes? Network access is especially important for small businesses with workers in different cities or states. A plan that works well for an employee near the company’s main office may not offer convenient doctors, pharmacies, or care options where a remote employee lives.
Prescription benefits are often administered through a pharmacy benefit manager (PBM), but that doesn’t mean you should evaluate the drug benefit in isolation. Check whether the plan’s preferred pharmacies are accessible to employees and whether prescriptions are treated differently at preferred, nonpreferred, mail-order, or specialty pharmacies. Then compare coverage for each employee’s medications against the plan’s full terms.
Build a medication list before opening the plan documents
For a meaningful formulary check, ask employees to identify their current prescriptions voluntarily and privately. Avoid collecting diagnoses or other health details unless there is a clear, appropriate reason and a secure process. You usually need the drug name, dosage, quantity, and refill frequency—not an explanation of why someone takes it.
- Include the exact medication name and strength. A brand and its generic equivalent may be treated differently. Note the usual quantity and refill schedule, such as a 30-day supply each month. Identify specialty medications, injectables, and drugs that require refrigeration or special handling. Ask whether the employee uses a particular pharmacy or mail-order service. Record whether the medication is already subject to a coverage restriction or exception request.
Keep this information confidential. Share only the minimum information needed with a broker, insurer, or other authorized party, and ask how it will be protected. Employees may prefer to check their own medications directly with the carrier or PBM.


What to compare in each plan’s prescription coverage
Don’t stop at “covered” or “not covered.” A medication can appear on a formulary but still cost substantially more or be subject to rules that affect access. For each drug, compare the following details in both plans.
What to check Why it matters Where to look Formulary status and tier A covered drug may be assigned to a generic, preferred brand, nonpreferred brand, or specialty tier, each with different costs. Current formulary or drug list; carrier or PBM confirmation Deductible and cost-sharing Some plans require the member to pay the negotiated cost until a deductible is met; others use a copay or coinsurance. Summary of Benefits and Coverage (SBC), plan documents, pharmacy benefit details Prior authorization The prescriber may need to submit information and receive approval before the plan covers the drug. Formulary restrictions or written carrier confirmation Step therapy The plan may require a trial of a different medication first, subject to its rules and any available exception process. Drug-specific coverage criteria Quantity limits The plan may cap the amount dispensed over a certain period. Formulary notes and pharmacy benefit documents Pharmacy network Cost and access may depend on whether the pharmacy is preferred, in-network, or eligible for mail order. Pharmacy directory and carrier confirmation Specialty drug rules Specialty prescriptions may have separate cost-sharing, designated pharmacies, or delivery requirements. Specialty drug list and plan documentsUse a plan comparison checklist—not a premium-only shortcut
Compare the plans side by side using the same assumptions. A one-page comparison sheet makes it easier to spot gaps and follow up with the carrier or broker. Include both prescription details and the basic medical plan terms that affect total costs.
- Monthly premium for the employer and each employee coverage tier Deductible, out-of-pocket maximum, and whether prescriptions count toward them Cost-sharing for each listed medication at the employee’s likely pharmacy Formulary status, tier, prior authorization, step therapy, and quantity limits Preferred pharmacy locations and mail-order availability Network access by employee zip code, including remote workers Coverage effective date, enrollment deadlines, and transition-of-care process Small-group eligibility, minimum participation, and contribution rules Renewal terms and how the carrier notifies members about formulary changes
For each prescription, estimate the employee’s cost over a realistic period, such as a year. Use the plan’s stated cost-sharing and ask the carrier or PBM to clarify how the deductible applies. An estimate is not a promise of what a claim will cost: actual pricing can depend on the pharmacy, benefit rules, and the way a claim is processed.
Verify the formulary check with the carrier or PBM
Formulary documents can be difficult to interpret, and online drug lookup tools may not show every restriction. Check that the formulary is current and matches the exact plan, network, and plan year under consideration. If a drug appears covered, look for notes such as “PA” for prior authorization, “ST” for step therapy, or “QL” for quantity limit.
When an answer is unclear, ask the carrier or PBM a precise question. For example: “For this plan and plan year, is this medication covered at this strength and quantity? What tier is it on? Does the deductible apply? Are there authorization, step-therapy, quantity-limit, or preferred-pharmacy requirements?” Ask for the response in writing or keep a dated record of the call, including the representative’s name and any reference number.
If an employee’s medication is not covered or has a restriction, ask about the plan’s exception and appeal procedures. The employee’s prescriber may need to provide supporting information. Do not assume an exception will be granted or that a medication will be covered the same way after the plan renews.
Why small businesses look outside the marketplace
Small employers often start with the public health insurance marketplace exchange because it offers a central place to review individual coverage options and, where available, small-business coverage. The exact programs and shopping routes ICHRA vs QSEHRA comparison depend on the state and the business’s circumstances. The exchange can be a useful reference point, but it may not be the only way to explore employer coverage.
Businesses may also ask a broker or contact carriers directly to compare available small-group plans. They might be looking for different network options, more help with enrollment, or a plan design that better fits their workforce. Availability varies by location and carrier, so compare actual plan documents rather than assuming an off-exchange plan offers broader access or better prescription coverage.
For an apples-to-apples comparison, identify the specific plan, network, plan year, and pharmacy benefit in each quote. Confirm whether the quoted premiums assume a particular employer contribution or employee participation level. A price without those conditions is not enough to make a reliable decision.
Broker versus direct-to-carrier shopping
A broker can gather quotes, explain plan differences, help with enrollment, and serve as a contact when questions come up. Ask how the broker is compensated, which carriers and plan types they represent, and whether they can help verify prescription details rather than only presenting premium estimates. Confirm whether any fee or other cost applies to the employer.
Shopping directly with a carrier can let an employer ask questions without an intermediary and may be useful for verifying plan-specific terms. But the employer may need to coordinate the comparison, resolve differences between quotes, and manage enrollment steps itself. In either route, get the same facts for each option: in-network providers for employee zip codes, prescription coverage details, eligibility rules, employer costs, and deadlines.
Understand small-group eligibility and participation rules early
Before spending time on plan comparisons, confirm whether the business and its workers meet the carrier’s small-group requirements. Rules differ by state, carrier, and plan type. Factors may include the employer’s size, which workers count as eligible employees, minimum employer contributions, and the percentage of eligible workers who must enroll.
Participation calculations can be affected by employees who have other qualifying coverage or who decline the plan, but the treatment of those cases depends on the applicable rules. Ask the carrier or broker to explain the calculation for your business in writing, including which employees are included and what documentation is needed. Also confirm enrollment windows, effective dates, and any waiting-period rules before announcing a plan choice.
These requirements are not administrative footnotes. A plan that looks suitable on paper may be unavailable if the business does not meet the rules, or the timing may not work for the intended start date. Put eligibility and participation near the top of the comparison sheet—not at the end.
Where an HRA-style arrangement fits
Some small employers consider a health reimbursement arrangement (HRA) rather than choosing one group plan for everyone. In broad terms, an HRA is an employer-funded arrangement that can reimburse eligible medical expenses employee health benefits for small business under defined rules. The type of arrangement matters: different HRA structures have different requirements for employee eligibility, notices, reimbursement, and how individual coverage may be used.
An HRA is not simply a cash allowance and does not automatically make every health plan or prescription eligible for reimbursement. Employers should work with a qualified benefits professional or administrator to identify the arrangement that fits, understand applicable federal and state requirements, and set up compliant administration before offering it. Employees should also receive clear information about what expenses can be reimbursed, how claims are submitted, and what happens when coverage or employment changes.
When comparing an HRA-style approach with a group plan, account for more than the employer’s budget. Consider employees’ ability to find individual coverage that works in their zip codes, the prescription coverage available to each person, and the administrative work involved. Individual plans can have different networks and formularies, so employees may not all have access to the same doctors or drug benefits.
Use reliable sources, then confirm the details
The public health insurance marketplace exchange is a useful place to review coverage information and identify options available through that channel. For general research, you can also use Google Search’s “follow” or “add to preferred sources” prompt, when it appears, to make trusted sources easier to find in relevant search results. Prefer official marketplace, state insurance department, carrier, and PBM materials over unsourced summaries.
Search results are a starting point, not a substitute for the actual plan documents. Formulary pages can change, and a general carrier page may not describe the exact plan being quoted. Confirm prescription coverage and restrictions for the plan year, network, and pharmacy benefit you are considering.
Make the decision with documented trade-offs
The better plan is not automatically the one with the lowest premium or the longest drug list. It is the plan—or benefits approach—that meets the business’s eligibility rules, gives employees practical access to care, and makes the costs and restrictions understandable. If one option has a lower premium but creates higher costs or coverage barriers for a key medication, write that trade-off down and discuss it with affected employees appropriately.
Confirm network access for every relevant employee zip code. Collect a confidential list of medications to check, with exact strengths and quantities. Compare formulary status, tiers, pharmacy access, and restrictions plan by plan. Verify small-group eligibility, participation, contribution rules, and deadlines. Compare total costs and administrative requirements, including any HRA option. Save the plan comparison checklist, source documents, and written carrier answers.A careful prescription coverage comparison takes more than a quick glance at the premium column. A current formulary check, clear answers about pharmacy rules, and a one-page plan comparison checklist give a small business a stronger basis for choosing—and help employees understand what the plan will and will not do.
