OPD and IPD explained

Every Thai hospital bill and every insurance policy splits care into two categories. Understanding which is which is the difference between a plan that pays and a plan that does not.

OPD - Outpatient Department

Any care where you go home the same day and are never formally admitted to a bed.

Typical examples
Consultations for flu, fever or infection; minor injuries and stitches; blood tests, X-rays and ultrasound; prescription refills; dental checkups; physiotherapy; vaccinations.
Typical cost
500-5,000 THB per visit, most commonly 1,500-3,000 THB at an international hospital.

IPD - Inpatient Department

Care that requires formal admission and at least one overnight stay in a hospital bed.

Typical examples
Surgery of any kind; childbirth; serious infections needing IV antibiotics; dengue or pneumonia admissions; cardiac events; recovery after a major procedure.
Typical cost
50,000 THB for a short admission to well over 1,000,000 THB for cardiac surgery or an intensive care stay.

What an IPD bill is actually made of

Insurers apply separate limits to each line of the bill, which is why two plans with the same headline limit can pay very differently.

  • Room & board

    Per-night charge, most often capped by a policy

    30%

  • Surgery & procedure fees

    Operating theatre, implants, anaesthesia

    25%

  • Doctor & specialist fees

    Surgeon, anaesthetist, daily ward rounds

    18%

  • Medication & supplies

    IV drugs, dressings, take-home prescriptions

    15%

  • Diagnostics & imaging

    Blood work, CT, MRI, ultrasound

    8%

  • Nursing & admin

    Ward nursing, admission and discharge paperwork

    4%

Percentages are indicative for a typical multi-day admission at a Bangkok private hospital. Room charge is the line most often capped by an insurance policy - if your plan caps the room at 4,000 THB and you choose a 9,000 THB room, you pay the difference and, on some policies, the same proportion of every other line.

Co-payment and deductible

A co-payment is a percentage of every bill you pay yourself, typically 10-20%. A deductible is a fixed amount you pay before cover begins at all. Both cut your premium and raise what you owe on the day.

Worked example - 500,000 THB admission

What you pay and what the insurer pays on a 500,000 THB hospital admission at different co-payment levels

Pick a co-payment level you could pay from savings tomorrow morning. A 30% co-payment looks attractive on the quote and painful in the ward.

How this maps to plan types

IPD-only plans

IPD-only plans cover admissions and surgery. Premiums are far lower and they protect you against the bills that could actually bankrupt you. You pay routine doctor visits yourself.

Comprehensive plans

Comprehensive plans add OPD cover for consultations, tests and prescriptions. They cost noticeably more, but a family using OPD ten times a year often gets the difference back.

If the budget only stretches one way, insure the IPD side first. A 3,000 THB doctor visit is an inconvenience; a 900,000 THB surgery is not.
