Short answer. No. The Civil Code exempts expenses for support, education, medical attendance, apprenticeship, ordinary equipment, and customary gifts from collation. Tuition, medical bills, and an ordinary, customary wedding gift are not added back into the estate or charged against that heir's share when the estate is eventually settled.
What the law says
Expenses for support, education, medical attendance, even in extraordinary illness, apprenticeship, ordinary equipment, or customary gifts are not subject to collation.

What collation is trying to catch, and what it is not
Collation is the process of bringing certain lifetime gifts a parent made to a child back into account when the estate is eventually divided, so that one heir does not end up better off than the others simply because of advances received while the parent was alive. Article 1067 draws a line around what does not get treated that way: expenses for support, education, medical attendance, apprenticeship, ordinary equipment, and customary gifts. These are treated as part of a parent's ordinary obligations and generosity toward a child, not as an advance on that child's inheritance.
Why medical bills are covered even when serious
The article specifically extends the exemption to medical attendance even in extraordinary illness. That phrase matters — it forecloses an argument that only routine doctor visits are excluded while a costly hospitalization or major treatment should be collated. Whether the medical expense was modest or substantial, if it was genuinely support given for the heir's health, it falls outside collation under this article.
Where a wedding gift fits
A wedding gift is covered to the extent it is customary — the kind of gift a parent would ordinarily give a child on that occasion, in keeping with the family's usual practice and means. The word "customary" is doing real work here: it distinguishes an ordinary, expected gift from something well beyond what would normally be given, and this article's exemption is written around gifts that fit the former description. A gift well beyond what the family's means or usual practice would support falls outside this exemption, and under Article 1061 the excess is brought back into the estate so it can be counted toward that heir's legitime, the same as any other lifetime donation.
What matters if this is being disputed
If a co-heir is arguing that tuition, medical costs, or a wedding gift you received should reduce your share, the relevant question under this article is what kind of expense it actually was — was it support, education, or medical attendance, or was it something else, like an outright advance of capital or property unrelated to these categories. Keep whatever records exist of the amounts spent and the purpose behind them, since that documentation is what will show the expense belongs in the exempted categories rather than among gifts that are collated.
