The moves insiders know. Now you do too.

Providers often bill before your insurer finishes processing the claim. The EOB says what you actually owe. If the bill is higher, the provider has to rebill.

“I’m happy to pay my share once the claim processes. Please hold the account until you can bill me per my EOB.”

A summary bill hides duplicates, unbundled tests and supply charges. You are entitled to the itemized version with CPT/HCPCS codes. Just asking sometimes gets charges removed.

“Please send me an itemized statement with CPT and revenue codes for each line, and put the account on hold while I review it.”

Adjustment codes starting with CO (contractual obligation), like CO-45, CO-97 or CO-197, are amounts the in-network provider agreed to absorb. If they bill you for it, quote the code back to them.

About 60% of US hospitals are nonprofits, and the IRS requires them to have a written financial assistance policy. Many cover households up to 300–400% of the federal poverty level, and you can apply even after you’ve been billed.

Hospitals routinely accept 30–50% off for prompt payment. Anchor to Medicare rates (2–3x Medicare is fair) and get the agreement in writing before you pay.

“I can pay $X today in full settlement if you can accept that. Can you confirm in writing?”

Paid medical collections and medical debts under $500 no longer appear on credit reports from the big three bureaus, and new debts can’t be reported for a year. Don’t let collection pressure rush you into paying a wrong bill.

It covers ER care (even out-of-network), air ambulances, and out-of-network anesthesiologists, radiologists or assistants at an in-network hospital. Uninsured? You’re entitled to a Good Faith Estimate, and you can dispute a bill that comes in $400+ over it.

Fewer than 1% of denied claims are appealed, yet a large share of appeals win. File the internal appeal (you usually have 180 days), then request an independent external review if you lose.

“Please send me the specific plan provision and clinical criteria used to deny this claim, and the name and credentials of the reviewer.”

Your doctor can talk directly with the insurer’s medical reviewer, which often flips the decision within days. Ask the office to schedule it; it’s faster than a written appeal.

If your plan has no in-network provider within a reasonable distance or wait time, you can request a gap exception so an out-of-network provider is covered at in-network rates.

Write down the date, rep name and call reference number. If a rep tells you something is covered and it’s later denied, the reference number is evidence for your appeal.

Annual physicals, many screenings, vaccines, contraception and well-woman visits are free in-network. Discussing a new problem during the visit can add a billed problem-oriented visit. Book a separate appointment for problems, or ask upfront how it will be coded.

The same blood panel can cost $30 at an in-network independent lab and $300+ at a hospital lab. Ask your doctor to send the order to your plan’s preferred lab.

Basic panels (CBC, CMP, lipids, A1c, TSH) often cost $10–$40 cash through direct-to-consumer lab services, sometimes less than your plan’s negotiated rate before the deductible.

Federal rules release most results immediately. Slightly-out-of-range values are common and often meaningless in isolation. Track trends, and message your doctor about anything flagged critical.

It’s on the back of the card. Nurses can tell you whether you need the ER, urgent care or nothing at all, which can save a $2,000 ER visit.

If the building says “Emergency” anywhere, expect ER facility fees. For a sprain, UTI or cold, find an in-network urgent care instead.

Most plans offer virtual visits for $0–$30. Pink eye, UTIs, rashes, refills and cold/flu are all well suited to video visits.

Clinics owned by hospitals can add a separate “facility fee” to an ordinary office visit. Independent practices usually don’t.

Hospitals must post prices, and insurers have cost estimator tools. MRIs, CTs and colonoscopies vary 5–10x between facilities in the same city.

For generics, discount cards and cost-plus pharmacies are often cheaper than your copay. Note that the cash price usually won’t count toward your deductible.

Mail-order or 90-day retail fills are usually cheaper per dose and mean fewer pharmacy trips.

If the covered alternatives don’t work for you, your doctor can request a formulary exception. Ask whether a different drug in the same class is on a lower tier.

Medicare caps insulin at $35/month, and the major manufacturers offer $35/month programs for most commercially insured and uninsured people.

With an HSA-eligible plan, contributions are pre-tax, growth is tax-free and medical withdrawals are tax-free. Pay small bills out of pocket, save receipts, and let the HSA grow; you can reimburse yourself years later.

Most FSA money is use-it-or-lose-it (some plans allow a $660 carryover or a grace period). Glasses, contacts, sunscreen, first-aid kits and many OTC meds qualify.

Once you reach your deductible or out-of-pocket max, care costs little or nothing until the plan year ends. Fit in the elective procedure, physical therapy or that specialist visit.

Even if you’re married, not a dependent, or have a job offering coverage. Coverage usually ends at the end of the month (or year) you turn 26, so set a reminder.

Losing coverage opens a 60-day special enrollment period on HealthCare.gov. Marketplace plans with subsidies are often far cheaper than COBRA, and your income may qualify you for a $0 premium plan or Medicaid.

You have 60 days to elect COBRA, and coverage applies back to the day your old plan ended. Some people wait and only elect it if something happens. Know the risk if you do this.
