If you mean that a person could have exclusive rights to property or in anyway utilize the excesses of capital for personal gains no. It may be possible for persons to organize their own practice but not in order to realize profits or control the means of production.
In no way can exclusive rights be set up or maintained over the means of production, small or large, under a communist system. So business in the capitalist sense could not be maintained. However if individual practices are to be seen they would likely fit into the system much the same as they do now. They would provide more personal and specified services than large clinics or service providers generally, or at least they would need to in order to be justified.
I am skeptical as to if those things would even be desirable, productive, or even possible once the market is abolished or completely controlled by the people.

Do you mean to say we must descend to a lower level, from the advanced workers to the mass, that we must write more simply and closer to life? Do you mean to say our aim is to descend closer to the “mass” instead of raising this already stirring mass to the level of an organized political movement?" --V.I. Lenin
