I doubt that.
Can. 564 A chaplain is a priest to whom is entrusted in a stable manner the pastoral care, at least in part, of some community or special group of Christ's faithful, to be exercised in accordance with universal and particular law.(emphasis added)
The “in part” section allows for others. Read the remainder of the thread and follow the link. The canon does not assign all these duties to a priest. It is impossible given the shortage of priests. Additionally, there are more nonCatholic patients in Catholic ones and their needs are often met by other ministers and their delegates. Distribution of communion, spiritual visits, ethics works on committees, are all often performed by non- clergy. The Sacraments, with few exceptions, are performed by priests. I tell you this from personal experience both locally and nationally.
