Check a medical bill before agreeing to pay

SettleADebt.com — D012 FORMULA-03

Focused equation-rendering correction | A016 Medical, dental and long-term care debt | Baseline: October 22, 2026 (America/Los_Angeles)

Disposition: Arithmetic corrected for publication formatting; underlying legal and contractual conclusions retain their existing verification limits.

All original hypothetical inputs are preserved. The ten coordinator-recomputed quantities are consistent with the formulas below. This supplement does not independently revalidate the governing legal rules, issuer agreement, or remaining D012 claims.

1. Source and evidence-reuse register

No new source IDs are assigned: this supplement corrects presentation and arithmetic, not source discovery.

2. Complete repaired worked examples

Example 1 — Hospital charity-care ceiling

Original assumptions: The hospital facility is subject to Internal Revenue Code § 501(r); the emergency or medically necessary care is covered by its FAP; the patient qualifies under that FAP.

Plain-text formula:

Plain text

AGB ceiling = Gross charges × AGB percentage

AGB ceiling = $20,000 × 0.28
            = $5,600

Result: $5,600 illustrative AGB ceiling.

This is not necessarily the amount owed. A qualifying 100% charity-care award could reduce responsibility to $0. A smaller FAP discount must still be considered alongside the applicable AGB limit.

The 28% rate is hypothetical. The hospital's actual FAP, eligibility determination, covered-provider list, AGB calculation and applicable charges must be verified.

Claim mapping: D012-C010.

Example 2 — Self-pay good-faith-estimate dispute

Plain text

Bill-estimate difference = Initial bill − Good faith estimate

Bill-estimate difference = $2,650 − $2,200
                         = $450

Excess above threshold = $450 − $400
                       = $50

Result: The $450 difference clears the $400 dollar threshold by $50.

That alone does not establish PPDR eligibility. The applicable GFE, individual provider/facility comparison, self-pay/uninsured conditions and other requirements still apply.

The original example states that the patient received the initial bill on July 1, 2026. That is not automatically the operative date for CMS's initial-bill-date rule. The actual date on the initial bill must be established before determining the 120-calendar-day initiation window.

The CMS fee information was separately corrected in D012 Correction-02; it is not recalculated or newly verified here.

Claim mapping: D012-C007–C008.

Example 3 — Standard CareCredit minimum payment

Original assumptions: $2,400 non-promotional new balance; no past-due amount, special promotional-payment component, or current-cycle interest/late fee in the 1% alternative.

Plain text

Alternative A = $30

Alternative B = $2,400 × 0.0325
              = $78

Alternative C = ($2,400 × 0.01) + $0
              = $24

Illustrative minimum = MAX($30, $78, $24)
                     = $78

Result: $78 illustrative minimum payment, subject to the agreement's rounding rules, account conditions and other applicable components.

This must not be mechanically applied to a deferred-interest promotion or special payment arrangement. The coordinator reviewed selected pages of the issuer's March 2026 terms, not every possible account-specific agreement.

Claim mapping: D012-C035.

Example 4 — Deferred-interest risk

Original assumptions: $2,400 daily balance and approximately 0.09039% daily purchase rate.

Plain text

Daily percentage rate = 0.09039%

Decimal daily rate = 0.0009039

Illustrative first-day interest
  = $2,400 × 0.0009039
  = $2.16936
  ≈ $2.17

Result: Approximately $2.17 for the first day.

This does not establish the total deferred interest for the promotion. Daily balances, purchases, payments, credits, allocation rules, promotional duration and the applicable account agreement affect the result.

Under the original cited deferred-interest terms, failure to pay the qualifying promotional balance in full by the specified deadline can trigger interest dating back to the original purchase date. That contractual conclusion remains subject to the actual promotional offer and issuer terms.

Claim mapping: D012-C033–C034.

Example 5 — Insolvency and medical-debt cancellation

Original assumptions: Financial position immediately before a $10,000 debt cancellation.

Plain text

Insolvency amount = Liabilities − Fair-market value of assets

Insolvency amount = $28,000 − $20,000
                  = $8,000

Potential insolvency exclusion
  = MIN($10,000 canceled debt, $8,000 insolvency)
  = $8,000

Potential remaining cancellation-of-debt amount
  = $10,000 − $8,000
  = $2,000

Result: $8,000 illustrative insolvency exclusion and $2,000 potentially remaining cancellation-of-debt amount.

This assumes the relevant debt produces cancellation-of-debt income and the insolvency exclusion applies as illustrated. Other exclusions, exceptions, tax attributes, basis rules and taxpayer-specific circumstances can change the tax result.

A medical purpose does not, by itself, establish that cancellation is tax-free.

Claim mapping: D012-C045–C046.

Example 6 — Nursing-home admission signature

The original clauses are preserved.

Clause A: “I personally guarantee all charges owed by my parent.”

Clause B: “I have legal access to the resident's funds and agree, without personal financial liability, to use those funds to pay the facility as required.”

For the assumed Medicare/Medicaid-participating nursing facility, the federal admission protections prohibit requiring Clause A as a condition of admission or continued stay.

Clause B reflects the permitted category of resident-fund representative arrangement, assuming the signer actually has the requisite legal access.

There is no numerical calculation in this example. Independent misconduct, representative authority and potential state-law obligations remain separate questions. The formula correction does not revisit the earlier case-law analysis.

Claim mapping: D012-C023; related correction D012-C024.

Example 7 — California ground-ambulance example

Original assumptions: California enrollee in a DMHC-regulated commercial full-service plan; covered noncontracted ground-ambulance transport.

Plain text

Illustrative patient responsibility = $250

Provider bill minus patient responsibility
  = $3,000 − $250
  = $2,750

Result: $250 illustrative patient responsibility under the stated DMHC coverage assumptions.

The $2,750 difference is not necessarily the amount the insurer must pay; reimbursement is determined separately under applicable payment rules.

Do not extend the example automatically to self-funded ERISA plans, Medicare Advantage, Medi-Cal managed care or specialized products.

Claim mapping: D012-C037.

Example 8 — Insurance-appeal calendar

Original assumptions: An ERISA plan subject to the specified claims regulation delivers a qualifying adverse benefit determination on May 1, 2026. The minimum appeal period is at least 180 days.

Plain text

Starting date: May 1, 2026

Elapsed calendar days after May 1:
May 2–31       = 30 days
June 1–30      = 30 days
July 1–31      = 31 days
August 1–31    = 31 days
September 1–30 = 30 days
October 1–28   = 28 days

Total = 30 + 30 + 31 + 31 + 30 + 28
      = 180 calendar days

Arithmetic result: October 28, 2026.

This uses the explicit counting assumption that May 1 is day zero and May 2 is day one.

It is not certification of the legal filing deadline. The applicable receipt date, plan language, regulatory classification, method of filing and any longer permitted appeal period must be established separately.

Claim mapping: D012-C014.

3. Repaired comparison matrix

The matrix is a navigation aid, not independent verification of each legal regime.

4. Replacement claim/example mapping

No claim ID has been renumbered, and no legal conclusion has been upgraded solely because its arithmetic is correct.

5. Coverage and residual holds

6. Researcher self-check

This pass repaired the original formulas and preserved every supplied hypothetical. It did not independently reopen the issuer PDF, underlying tax statutes, CMS regulations or other cited legal sources. Coordinator-supplied calculations and source observations are distinguished from independent verification.

No new legal or contractual proposition is asserted beyond the qualified original material. No other D012 claim is approved by implication. No independent review, publication, contact, account modification or local file save occurred.

Final disposition: D012 FORMULA-03 completed for arithmetic and rendering. Substantive legal, eligibility, contractual, state-law and tax holds remain in place.
