The first set of rules is for financial requirements (such as rules for copayments) and for
treatment limits that you can count (such as number of visits).
,
The other set of rules deals
with how treatment is accessed and under what conditions (such as obtaining permission
from your health plan before going to MH/SU treatment).
Here are some ways in which MH/SU and physical health benefits must be comparable:
Co-payment (or simply co-pay). A co-pay is a fixed amount you pay for each
covered service such as an outpatient doctor’s visit. For example, generally if your
co-pay for all outpatient physical health benefits is $20, then your co-pay for
outpatient mental health or substance use benefits must be $20 or less.
Yearly visit limits. If there are no yearly limits on all outpatient office visits to
medical providers, there should generally be no yearly limit for outpatient office visits
to an MH provider.
Prior authorization. Prior authorization (sometimes called preauthorization, prior
approval, or precertification) means that a doctor from your plan must confirm that
you need a service before it begins. Generally speaking, if your health plan does not
require prior authorization for any medical/surgical visits, a plan will not be able to
require it for MH/SU related visits. Once your treatment begins, rules for continuing
your care should be based on a comparable process for both mental health and
physical health benefits.
Proof of medical necessity. Medical necessity standards are used to determine
appropriate care for different medical conditions. The standards are based on
research showing that a treatment is effective. A health plan must use a similar
process to create medical necessity standards for MH/SU services, compared to the
process used for physical health services.
These usually are called quantitative treatment limitations or QTLs. They include the number of visits or days
covered or frequency of treatment.
A plan may not impose a financial requirement or quantitative treatment limitation applicable to mental health
or substance use benefits in any classification that is more restrictive than the predominant financial
requirement or quantitative limitation of that type applied to substantially all medical/surgical benefits in the
same classification.
These are usually called non-quantitative treatment limitations or NQTLs. NQTLs deal with how treatment is
given and under what conditions (such as medical necessity or prior authorization requirements). A plan may
not impose an NQTL with respect to MH/SU benefits unless any processes, strategies, evidentiary standards,
or other factors used in applying the limitation to MH/SU benefits are comparable to and applied no more
stringently than those used in applying the limitation with respect to medical/surgical benefits.
