The difference between basic ADL and IADL: which activities fall into each category, why most insurance definitions rest on ADL alone, and why a decline in IADL still matters greatly to a claim.
Two levels of functioning
The professional literature separates two kinds of daily activity, and that distinction is critical to understanding long-term care claims.
Basic ADL (BADL) are the essential activities concerning the body itself: bathing, dressing, eating, mobility, transfers and continence.
IADL are more complex activities that make independent life in the community possible: managing money, taking medication, using the telephone, shopping, cooking, cleaning and getting about outside the home.
Why this matters in a claim
Most definitions in long-term care insurance policies rest on basic ADL alone. That is, an inability to manage a bank account or to cook does not, in itself, satisfy the definition.
This is the main reason for refusals at an early stage. A family sees a significant decline — the parent has stopped managing money, gets confused about medication, does not go out to the shops — and files a claim. But all of these are IADL.
The practical conclusion: while the difficulty is still concentrated in IADL, it may be too early to file on the functional route — but it is certainly not too early to start documenting, and the cognitive route is sometimes relevant.
A decline in IADL is not without value
The opposite mistake is to ignore IADL entirely. It matters a great deal — simply in a different place.
First, a decline in IADL is usually the earliest sign of cognitive decline. Someone who can no longer manage medication or money is showing difficulty in judgment and planning — and those are exactly the components of cognitive incapacity.
Second, it establishes a timeline. If it is documented that the parent stopped managing the account two years ago, that helps to show when the process began — even if the impairment in ADL appeared later.
So the recommendation is to document both: the basic daily activities and the complex ones, with dates.
The full list
For orderly documentation, it is worth going through both lists and marking what changed and when.
- ADL — bathing, dressing, eating, mobility, transfers, continence
- IADL — managing money and payments
- IADL — taking medication at the right dose and time
- IADL — using the telephone and means of communication
- IADL — shopping and stocking up
- IADL — preparing food and cooking
- IADL — cleaning the house and laundry
- IADL — getting about outside the home and using transport
Frequently asked questions
What is the difference between ADL and IADL?
Basic ADL covers essential activities — bathing, dressing, eating, mobility, transfers and continence. IADL covers complex activities such as managing money, medication, shopping and cooking.
Is a decline in IADL enough for a long-term care claim?
Most definitions in policies rest on basic ADL alone, so a decline in IADL does not in itself satisfy the functional definition. It is, however, highly relevant to the cognitive incapacity route.
So why document IADL at all?
For two reasons: it is the earliest sign of cognitive decline and therefore relevant to cognitive incapacity, and it establishes a timeline showing when the process began.
What is BADL?
Basic Activities of Daily Living — the basic daily activities: bathing, dressing, eating, mobility, transfers and continence. These are the activities at the centre of most insurance definitions.
