The sacrament of communion expresses the unity of the church. This sacrament celebrates a joint meal. Every other sacrament is done for the benefit of an individual.
Eastern Orthodox Christians are permitted with special permission to receive the Eucharist from a Catholic Church on certain occasions and other non-Catholic Christians may be able to receive if they are in danger of death, express a belief in the Eucharist, and ask for it on their own initiative. The reason for this is that only the Catholic Church and the Orthodox Church believe in the Eucharist in the proper sense, and furthermore, the Eucharist is a sacrament of unity within the Church, and it would be wrong for those who do not share fully in the unity of the Catholic Church to receive it.

The short answer is YES. The path to unity depends on the form the 'leaving' took. If the person simply stopped going to Mass and instead attended services at the Baptist church, then experiencing the sacrament of Confession will bring back the unity. If, however, the leaving was 'formal' let's say a declaration of some kind to the Bishop, to the community or to the public, then it would be proper to formally reconcile first with the Bishop.
