CO-149 Denial: Category Lifetime Maximum Reached

CO-149 denies because a lifetime maximum for a specific benefit category has been exhausted. Because the prohibition on lifetime dollar limits attaches to essential health benefits, the category named is the whole question.

What CO-149 means

Where the category falls within essential health benefits, a lifetime dollar limit on it is impermissible on a compliant plan. Where it does not — some supplemental or excepted categories — the limit may stand. Beyond legality, accumulators are frequently wrong: services counted against the wrong category, or amounts accumulated that should not have been, and requesting the accumulator history is how that is tested.

Why CO-149 fires

A lifetime dollar limit was applied to a category within essential health benefits.
Services were accumulated against the wrong category.
The accumulator includes amounts that should not count toward the maximum.
The category sits outside essential health benefits and the limit is lawful.

Is CO-149 worth appealing?

Often worth appealing

Two arguments, in order: whether the limit is lawful for this category, and whether the accumulator is right. The second is checkable and wrong more often than practices assume.

How to resolve or appeal CO-149

1
Identify the category
And whether it falls within essential health benefits for this plan.
2
Request the accumulator history
What was counted, when, and against which category.
3
Challenge misattributed amounts
Services counted against the wrong category inflate a maximum that has not truly been reached.

CO-149 — frequently asked

Can I see the accumulator?

You can ask, and members can request it as part of their claim file. Errors in what was counted are common enough to make the request worthwhile.

Is a category limit the same as a lifetime maximum?

It is a narrower version of one, and the same prohibition applies where the category is an essential health benefit.
