Plan for a long hospital stay and a gap in Korean indemnity coverage
For a family managing a parent’s or spouse’s long stay in a rehabilitation or long-term care hospital, the date insurance stops can matter as much as this month’s payment.
This calculator organizes the expected coverage end, exclusion period, exhausted-limit gap and resumption date, then estimates the cash the family must fund during a 12-month budget period.
The gap cost is the spending that must be funded while the selected benefit is unavailable.
It does not remove the usual deductible, caregiving bill or other excluded expenses during otherwise covered periods.
Korea-specific rules, checked on 2026-11-08
This guide concerns Korean silson medical indemnity insurance and the policy terms verified for the 2026 rule set.
A generation label alone cannot establish entitlement, whether admissions have the same cause, or whether inpatient treatment is medically necessary.
Until your insurer confirms the applicable terms, read the result as an assumption and request written confirmation of the benefit unit, paid amount, exhaustion date and resumption date.
Prepare the dates, payment statement and monthly amounts
First admission and budget start
The first date anchors the selected coverage cycle.
If coverage has already resumed, use the current cycle start confirmed by the insurer.
The budget runs from your budget start to the day before 12 calendar months have elapsed.
These dates serve different purposes and do not have to be identical.
Limit and benefits already paid
Enter payments already charged to the current benefit unit through the day before the budget starts.
This amount reduces the remaining limit; it is not new income and must not be deducted again from future bills or the monthly expected benefit.
For annual limits, include other claims using the same benefit unit in that insurance year.
Total monthly spending
Add the patient’s NHI-covered copayment, non-covered charges, room supplement, caregiving and other expenses once each.
Use spending before indemnity reimbursement, not the hospital’s full bill including the amount paid by National Health Insurance.
Keep the cost scope consistent when entering home-care or nursing-home alternatives.
Monthly benefit before gaps and limits
Use the insurer-confirmed expected monthly payment for the selected benefit during normal coverage.
Do not combine covered and non-covered benefits governed by separate limits.
The expected benefit cannot exceed total spending, and previous payments cannot exceed the selected limit.
Prepare your policy wording, itemized medical bill, admission/discharge record and insurance payment statement.
If the limit has already been exhausted, also obtain the insurer-confirmed actual exhaustion date.
The monthly assumption is not used to reconstruct historical payments before the budget starts.
The calculator does not need a name, diagnosis or KCD disease code.
Choose one of four confirmed policy models
1. Custom covered days and excluded days
Use this for first-generation or individually different terms after checking the actual policy.
A combination such as 365 covered days and 180 excluded days is an example, not a universal statutory first-generation rule.
A monetary limit may also run out before the covered-day window ends.
2. Confirmed 365-day coverage and 90-day exclusion
Select this for a standardized contract sold before 2016 only if its wording confirms this model.
The first day counts toward 365 covered days, followed by 90 excluded days and a new coverage cycle.
Certain policies sold from April 2014 contain a separate readmission provision after 180 days from the last paid admission’s discharge.
The calculator does not automatically treat readmission as a new disease or reset the cycle.
3. Limit exhaustion under 2016-revision and third-generation terms
Where these terms apply, passing 365 days alone does not stop payment before the benefit limit is exhausted.
The exclusion begins the day after exhaustion.
Resumption is the later of exhaustion date + 91 days and current cycle start + 365 days.
This implements the 275-day threshold while keeping the exhaustion date itself within the covered period, as illustrated in official policy examples.
4. Insurance-year limit for fourth- and fifth-generation contracts
An insurance year runs from the contract anniversary to the day before the next anniversary.
Once its limit is exhausted, the gap lasts until the next anniversary, assuming the policy remains in force and renews.
Do not apply the older 275-day/90-day model automatically to fourth- or fifth-generation coverage.
Run covered, non-covered, serious and non-serious benefit units separately when their limits differ.
Official examples explain the inclusive date boundaries
These historical policy examples demonstrate date counting.
They do not establish that every policy sold in the example year, or your current policy, has the same terms.
365 days followed by a 90-day gap
With first admission on 2014-03-01, the 365th covered day is 2015-02-28.
The excluded period runs from 2015-03-01 through 2015-05-29, and coverage resumes on 2015-05-30.
Omitting the admission day or resuming on the last excluded day produces a one-day error.
Later limit exhaustion
For first admission on 2014-03-01 and exhaustion on 2015-04-30, the gap is 2015-05-01 through 2015-07-29.
Coverage resumes on 2015-07-30, or exhaustion date + 91 days.
The exhaustion date can include a partial benefit, so the whole day is not counted as an unpaid gap day.
Earlier limit exhaustion
With the same first admission date and exhaustion on 2014-07-31, waiting only 90 days is insufficient.
Resumption is 2015-03-01, which is first admission + 365 days.
Budget for the gap starting on 2014-08-01 through the day before resumption.
An already exhausted policy needs its actual exhaustion date as well as its payment total.
How daily calculations become the monthly budget
Formulas and rounding
- Daily spending = monthly spending ÷ calendar days in that month
- Daily expected benefit = pre-gap monthly benefit ÷ calendar days in that month
- Modeled payment = the smaller of the eligible daily benefit and the remaining limit
- Out-of-pocket cost = spending − modeled insurance payment
- Monthly values are rounded to whole KRW; the total sums the displayed monthly values
At monthly spending of KRW 1,000,000 and a monthly expected benefit of KRW 800,000, a complete normally covered month with enough limit leaves KRW 200,000 to fund.
A fully excluded month leaves KRW 1,000,000.
Partial months use the actual month length, so the daily amount differs between February and a 31-day month.
The model spreads costs evenly across days.
A 12-calendar-month budget beginning midmonth can span 13 monthly rows because of the partial months at each end.
Surgery concentrated on one date or a delayed claim decision can change the actual exhaustion date and the date cash arrives.
This is not a claim-processing or deposit-date calendar, and families should separately plan cash for hospital payment deadlines.
Keep annual limits separate from admission limits
Combining covered and non-covered limits can overstate the period of available benefits.
Total spending covers the whole household bill, while the expected benefit covers only the selected unit; payments from other units are not combined automatically.
Calculate separate units in separate runs, but do not add their household out-of-pocket totals because that would count the same gross spending twice.
Other inpatient or outpatient claims may also have used the selected annual benefit unit.
Fifth-generation non-serious non-covered admission limit
The 2026-05-06 launch materials distinguish a KRW 10,000,000 annual limit, a KRW 3,000,000 limit per hospital/clinic admission, and a 50% deductible for this benefit.
When your terms confirm this restriction, enter the remaining limit for the same admission separately.
If KRW 1,000,000 of a KRW 3,000,000 admission limit has been used, enter KRW 2,000,000 remaining.
A new insurance year does not automatically restore the same admission’s remaining allowance.
After it is exhausted, resumption may be undetermined; ask the insurer whether a later admission is recognized as new.
KRW 2 million and KRW 5 million deductible caps and NHI refunds
Fourth-generation KRW 2 million cap
The verified fourth-generation provision concerns the 20% deductible for covered inpatient treatment.
It is not a cap on all non-covered charges or caregiving costs.
For third-generation and other terms, check the eligible deductible and insurance-year definition in the actual policy.
Additional payment remains subject to the applicable benefit limit.
Fifth-generation KRW 5 million cap
The serious non-covered benefit’s annual deductible cap applies to specified inpatient treatment at tertiary or general hospitals.
Do not apply it automatically to an ordinary long-term care hospital or to non-serious non-covered treatment.
Ask about the rider, eligible treatment, hospital category and excluded items before estimating additional reimbursement.
The calculator does not automatically add payments above KRW 2 million or KRW 5 million, or universally subtract an NHI out-of-pocket ceiling refund.
If the insurer-confirmed monthly expected benefit already includes an adjustment, do not add it again.
Check the policy-specific handling of refundable NHI amounts and do not count an unconfirmed future refund as cash available today.
Compare care alternatives only after clinical approval
The comparison uses the same budget period for continued hospitalization, home care and a nursing home.
Before the transition date it uses hospital spending less modeled insurance payments; from that date it prorates the alternative’s monthly out-of-pocket cost.
It does not assume hospital indemnity payments continue unchanged at home or in a nursing home.
Make the estimates comparable
- Include visiting care, gaps in family availability, transport for outpatient visits and supplies in home-care estimates.
- For a nursing home, confirm long-term care eligibility, covered copayments and non-covered food or other charges.
- A Korean long-term care hospital and a nursing home have different institutional and insurance treatment.
- Add one-time transport, deposits and similar costs separately outside the recurring monthly comparison.
A lower modeled cost does not establish that discharge or transfer is medically appropriate.
Confirm treatment needs, safe caregiving and clinician approval, then discuss a practical plan with the hospital’s medical social-work team.
The calculator does not recommend admissions or discharges to obtain insurance payments or reclassify the same disease.
Read the result and take the next step
- Confirm the model: establish the current wording and benefit unit with the insurer rather than relying on the generation name.
- Align the payment cutoff: use cumulative payments through the day before budget start and the actual exhaustion date when relevant.
- Read dates in sequence: review the first end/exhaustion, gap start, gap end and expected resumption.
No gap within the observation period is not a promise of indefinite coverage.
- Fund the monthly balance: include normal deductibles and excluded expenses as well as the gap budget.
- Obtain written confirmation: send the dates and policy clause to the insurer, then coordinate a clinically appropriate care plan.
Correct reversed dates, payment amounts above spending, or cumulative payments above the limit before calculating.
For the annual model, the policy-year start must identify the insurance year containing the budget start.
For a February 29 anniversary, verify the insurer’s actual renewal convention.
Update the assumptions when treatment, spending, policy terms or confirmed payments change.
Frequently asked questions
Does every policy stop after 365 inpatient days?
No.
Fixed-day rules, exhaustion rules and insurance-year limits are different models; fourth- and fifth-generation terms do not automatically inherit the older 90-day exclusion.
Is every first-generation exclusion 180 days?
No.
Confirm the covered and excluded days in the specific benefit wording and enter those values; 365/180 is only an example.
Does readmission after 180 days automatically count as a new disease?
The relevant clause and insurer’s assessment are necessary.
Even where post-April-2014 terms contain such a provision, this tool does not automatically reset the cycle or recognize a new disease.
Should I deduct benefits already paid from the monthly expected benefit?
No.
Payments through the day before budget start reduce the remaining limit once; deducting them again from future benefits or bills double-counts them.
Is every zero-payment day an exclusion day?
Entering a zero monthly expected benefit does not itself create an exclusion.
The model separates policy exclusions from exhausted-limit gaps and records any unpaid portion on the exhaustion date as out-of-pocket spending.
Does an admission limit reset at the annual renewal?
Annual and same-admission limits must be checked separately.
This calculator does not reset the admission allowance at an anniversary; recognition of a new admission and possible resumption requires insurer confirmation.
Are long-term care hospital non-covered charges and caregiving fully reimbursed?
Do not determine reimbursement from the generation or institution name alone.
Separate eligible and excluded charges using the itemized bill and enter only an insurer-confirmed benefit.
Keep caregiving and other non-reimbursed expenses in total spending.
Why are deductible-cap payments and NHI refunds not added automatically?
Eligibility depends on benefit type, hospital category, insurance year and actual wording.
Automatic credits could overstate reimbursement, and an adjustment already reflected in the monthly benefit must not be counted twice.

Insurance Business Act Article 127 provides the foundation for policy documents; it does not itself prescribe the 90-day interval.
Historical contracts require their own original wording and conversion or re-enrollment history.
Recheck benefit units after standard-term amendments, conversion, re-enrollment or a change in the insurer-confirmed payment.
A future 12-month result assumes the currently confirmed conditions remain applicable.
Turn the coverage dates into a practical care budget
Match the inputs to your payment statement and review the out-of-pocket cost in the first gap month.
Request written confirmation of the benefit unit, paid total, exhaustion date and resumption date, then ask the clinical and social-work teams about an appropriate care plan.
Use the insurance claim estimate calculator to help prepare a starting monthly benefit and the silson generation comparison to explore cost differences.
Use your own policy and the insurer’s confirmation for the final benefit assumption.
