Question:
In the Eastern Catholic Churches, Can One Receive Communion with a Serious Sin on One’s Soul?
Answer:
The Catechism of the Catholic Church:
1457 … Anyone who is aware of having committed a mortal sin must not receive Holy Communion, even if he experiences deep contrition, without having first received sacramental absolution, unless he has a grave reason for receiving Communion and there is no possibility of going to confession.57 …
57 Cf. Council of Trent (1551): DS 1647; 1661; CIC, can. 916; CCEO, can. 711.
The Catechism References there the Eastern Code of Canon Law 711 which goes into that one is not to receive the Divine Eucharist if one is conscious of serious sin (mortal sin) (outside the exceptional circumstance of a serious reason (grave reason), no possibility of confession, act of perfect contrition and resolve to go to confession as soon as possible–see the Canons for details).

And from the Byzantine Catholic Church in America website -from the Congregation for the Eastern Churches :
“In it, as affirmed by can. 718 of the Code of Canons of the Eastern Churches, the faithful who have committed sins after Baptism and resolve to lead a new life, “through the ministry of the priest, having themselves made a confession and accepted an appropriate penance, obtain forgiveness from God and at the same time are reconciled with the Church.” This confession, individual and integral, with absolution, constitutes the
only ordinary means by which the Christian faithful aware of a serious sin can obtain omission.[74] Even if serious sins have not been committed, it is strongly recommended that all the Christian faithful frequently receive this sacrament, especially during times of fasts and penance.”

ENCYCLICAL LETTER
ECCLESIA DE EUCHARISTIA
Bl. Pope John Paul II
"The Apostle Paul appeals to this duty when he warns: “Let a man examine himself, and so eat of the bread and drink of the cup” (1 Cor 11:28). Saint John Chrysostom, with his stirring eloquence, exhorted the faithful: “I too raise my voice, I beseech, beg and implore that no one draw near to this sacred table with a sullied and corrupt conscience. Such an act, in fact, can never be called ‘communion’, not even were we to touch the Lord’s body a thousand times over, but ‘condemnation’, ‘torment’ and ‘increase of punishment’”.73
Along these same lines, the Catechism of the Catholic Church rightly stipulates that “anyone conscious of a grave sin must receive the sacrament of Reconciliation before coming to communion”.74 I therefore desire to reaffirm that in the Church there remains in force, now and in the future, the rule by which the Council of Trent gave concrete expression to the Apostle Paul’s stern warning when it affirmed that, in order to receive the Eucharist in a worthy manner, “one must first confess one’s sins, when one is aware of mortal sin”.75"
Now lets see: what is that foot note 74 there:
It references the Catechism of the Catholic Church, the (Roman) Code of Canon Law AND the EASTERN code
74No. 1385; cf. Code of Canon Law, Canon 916; Code of Canons of the Eastern Churches, Canon 711.

Oh and for added interest it quote the Ec. Council of Trent
And Pope Benedict XVI in his Catecheses with Children said:
"Only in that case, when you are in a state of “mortal” sin, in other words, grave (sin), is it necessary to go to confession before Communion. This is my first point. "

- What is required to receive Holy Communion?
1385-1389
1415
To receive Holy Communion one must be fully incorporated into the Catholic Church and be in the state of grace, that is, not conscious of being in mortal sin. Anyone who is conscious of having committed a grave sin must first receive the sacrament of Reconciliation before going to Communion.
