Mental Health Coverage — Mental Healthcare Act 2017 Compliance
Section 21(4) of the Mental Healthcare Act, 2017 requires insurers to cover mental illness on the same basis as physical illness. This lesson explains what the Act means by mental illness, what 'same basis' does and does not promise, and how in-patient and out-patient treatment differ.
The rule and why it exists
Health insurance has to treat illnesses of the mind and of the body alike. That is the effect of the Mental Healthcare Act, 2017, whose section 21(4) requires every insurer to make provision for medical insurance for the treatment of mental illness on the same basis as is available for the treatment of physical illness.
The duty applies to all health policies. It rests on a simple idea of equality: an illness is not to be treated worse by an insurer only because it affects the mind.
What counts as mental illness
The Act defines mental illness as a substantial disorder of thinking, mood, perception, orientation or memory that grossly impairs judgment, behaviour, capacity to recognise reality or ability to meet the ordinary demands of life. It expressly includes mental conditions associated with the abuse of alcohol and drugs.
The definition does not include intellectual disability, which the Act calls mental retardation and describes as a condition of arrested or incomplete development of mind.
What 'same basis' means
Same basis means the policy's ordinary terms apply to a mental illness exactly as they would to a physical one: the sum insured, the waiting periods, the limits and the general exclusions. A claim cannot be refused merely because the illness is mental.
It does not mean unlimited or special cover. If a term would apply to a physical illness in the same circumstances, it applies here too, and each claim still turns on the policy wording.
In-patient and out-patient treatment
Much mental health care is delivered without admission: psychiatric consultations, therapy sessions and medicines. That is out-patient treatment. A policy that covers only hospitalisation pays for in-patient treatment of a mental illness, as it does for a physical illness.
Out-patient consultations and therapy are payable where the policy has an out-patient (OPD) benefit. This is not a special restriction on mental illness; a hospitalisation-only policy does not pay for an out-patient visit to a physician for a physical illness either.
Rules at a glance
Illustration: two claims, one policy
Imran holds a health policy that covers hospitalisation only. In one year he is admitted for a week with severe depression, and later attends weekly therapy sessions without admission.
The admission is an in-patient claim and is assessed like any other hospitalisation under the policy: the same sum insured, the same limits, the same waiting periods. The therapy sessions are out-patient treatment. Because his policy has no OPD benefit, they are not payable, just as out-patient visits for a physical illness would not be.
Key points
- Section 21(4) of the Mental Healthcare Act, 2017 mandates insurance for mental illness on the same basis as physical illness.
- The duty applies to every insurer and to all health policies.
- Mental illness under the Act includes conditions associated with alcohol and drug abuse and does not include intellectual disability.
- Same basis means the policy's ordinary sum insured, waiting periods, limits and exclusions apply equally.
- A claim cannot be refused merely because the illness is mental.
- Out-patient therapy and consultations are payable only where the policy has an OPD benefit.
Common misunderstandings
- Same basis does not mean every mental health expense is paid: the policy's ordinary limits, waiting periods and exclusions still apply.
- The mandate is not limited to special 'mental health plans': it applies to all health policies.
- Addiction-related mental conditions are not outside the Act's definition: it expressly includes conditions associated with alcohol and drug abuse, though a claim still depends on the policy wording.
- Intellectual disability is not mental illness under this Act: the definition leaves it out.
Questions people ask
Can an insurer apply a waiting period to a mental illness?
Yes, if the same waiting period would apply to a physical illness under that policy. What it cannot do is treat the illness less favourably because it is mental.
Are therapy sessions covered?
Where the policy has an out-patient benefit, on its terms. A hospitalisation-only policy pays for in-patient treatment.
Which provision should be quoted?
Section 21(4) of the Mental Healthcare Act, 2017.
Does the insurer need a separate product to comply?
The duty is to cover mental illness on the same basis as physical illness in health policies generally, not to offer a separate product.
