Medical Bill Negotiation Services Compared (Resolve vs Goodbill vs DIY vs DFY)

Read the guides, send your own letters, make your own calls

What it is: Use a comprehensive guide (like our complete medical bill negotiation guide) to walk through the dispute process yourself. Request the itemized bill under HIPAA, identify coding errors, write the dispute letter citing the right statutes, mail it certified, follow up by phone, escalate if needed.

Strengths: Costs nothing but time. You learn the framework, which makes you better equipped for future bills. Full control over the process. Can be done at your own pace.

Weaknesses: Time investment is real (3-5 hours over 60 days for a single bill — more for complex multi-provider cases). Steep learning curve on the legal framework — HIPAA, NSA, 501(r), FDCPA all matter and citing them incorrectly weakens the dispute. Phone calls with billing departments require some skill to be effective.

Right for: Simple bills with one clear dispute path (e.g., a single coding error you've already spotted). Bills under $500 where the math doesn't justify any paid service. People who like the documentation work and have the time. Anyone with multiple bills over time who wants to learn the system once.

Wrong for: Multi-provider cases (anesthesia + facility + radiology + ER physician separately billed). Cases with multiple complicating factors (in collections AND NSA-eligible AND charity-care eligible). Time-poor users who'd rather pay than spend evenings on this. Anyone who's emotionally drained by the bill and can't be objective on negotiation calls.

Letter generator — fills in your bill details, picks the right statute path

What it is: An 8-step form captures your bill details (hospital, date of service, billed amount, insurance status, in/out of network status, income for 501(r) check). The tool's routing engine picks the correct dispute path (NSA / 501(r) / coding errors / prompt-pay / HIPAA), generates a personalized letter with the right citations and your specific bill data, and outputs a PDF ready to print and mail.

Strengths: 80% of the time savings of full DFY at 10% of the cost. No learning curve — the tool picks the right path for you. The letter is statute-cited and personalized. Flat fee, you keep 100% of the savings. 60-day money-back guarantee. Works for any bill size (no minimum).

Weaknesses: You still mail the letter, make the follow-up calls, and handle escalation if needed (~1-2 hours over 60 days). If you're not comfortable on the phone with billing departments, this still requires that skill.

Right for: Bills $500-$5,000 where the value of speed (10 min vs 3 hours) is worth $29. People comfortable with one phone call but not wanting to learn the legal framework. Anyone who wants the right letter without weeks of research.

Wrong for: Bills under $200 where even $29 is a meaningful percentage of the bill. People who absolutely don't want to make any phone calls (DFY is better for that). Multi-bill complex cases (DFY handles those better).

Concierge negotiation — they do everything, take a percentage of what they save you

What it is: You upload your bill and grant authorization. The service handles all letters, calls, and escalation. You pay a percentage of whatever they save you. If they save you nothing, you pay nothing.

The two main players:

• Resolve Medical Bills — contingency, ~25% of savings. Established service with a sizable ops team. Generally good with mid-to-large bills ($1,000+). Online intake, web-based case management.
• Goodbill — contingency, ~25-35% of savings depending on case complexity. Similar model to Resolve. Heavier focus on app-based interface.

Strengths: Zero upfront cost — pure pay-for-performance. Aligned incentives on big wins (the more they save you, the more they make). Larger ops teams mean they can handle case volume. Established relationships with billing departments at major hospital systems.

Weaknesses: The cut is significant on big wins — on a $5,000 reduction, you keep $3,250-$3,750 vs. $5,000 with flat-fee or DIY. Misaligned incentives on small cases — they may decline cases where the expected reduction × commission rate doesn't justify their time. Less aggressive on cases with weak leverage (no errors found, fair pricing already). You don't control the negotiation strategy.

Right for: Very large bills ($10,000+) where their efficiency justifies the cut. Cases where you have zero upfront budget for any paid service and are willing to accept the contingency cut on the upside. Multi-bill complex cases where their experience pays off.

Wrong for: Small-to-mid bills ($500-$3,000) where DIY or the $29 tool keeps materially more money. Cases with very strong leverage (clear coding error, clear NSA violation) where you'd be paying 25-35% for an outcome you could have achieved yourself in a week.

We handle the whole negotiation — flat fee regardless of savings

What it is: Pay $299 upfront. Fill out the intake form (5 minutes). Email us your bill. We handle everything: letters, certified mail, follow-up calls, charity-care application if eligible, escalation to CMS or state insurance commissioner if needed. Weekly status updates. You pay the negotiated bill at the end.

Strengths: Flat fee regardless of case size — on a $5,000 reduction you keep $4,701, vs. $3,250-$3,750 with contingency. 60-day money-back guarantee (full $299 refund if we can't reduce the bill at all). Aligned incentives toward maximum reduction (we don't make more by leaving money on the table). You truly do nothing except pay the reduced bill at the end.

Weaknesses: Upfront cost — you pay $299 even if your case turns out to need only minimal work. $1,500 minimum bill size (smaller bills route to the $29 tool where the math is better). Newer service with smaller ops team — case volume is throttled to maintain quality.

Right for: Bills $1,500-$10,000 where the flat fee is much less than a contingency service would charge. Time-poor users who don't want to handle anything themselves. Multi-provider cases (one fee, we handle all the pieces). Anyone who values predictability ("I know what this costs upfront") over pay-for-performance.

Wrong for: Bills under $1,500 (use the $29 tool). Customers who already have substantial leverage documented and just need the letter (use the $29 tool — we'll do exactly what you'd do, just for $270 more). Cases in active litigation (need an attorney, not a billing service).
