What is the difference between a public and a private patient? Perhaps you don't need separate classes. It might just be some sort of 'patientType' enum property you add to your Patient class.

If you believe you need separate classes, it seems like a pretty simple matter of creating those two classes, derived from your existing class.

Derive two patient classes from some base class and mark one of the with the access modifier "private" and another one with access modifier "public".

First, as SorenMad pointed out to you in his comment: consider if you really need two separate Classes.

Here's a rough-sketch:

C#

public abstract class Patient
    {
        // fields, properties, methods which both
        // Public and Private patients share are
        // defined/implmented here
        public Guid Patient_ID { private set; get; }
        public string Patient_Name { set; get; }
        public DateTime Patient_Dob { set; get; }
        public string Patient_Sex { set; get; }

        public Patient(string name, DateTime dob, string sex)
        {
            Patient_ID = Guid.NewGuid();
            Patient_Dob = dob;
            Patient_Name = name;
            Patient_Sex = sex;
        }
    }

    public class PublicPatient : Patient
    {
        // fields, methods, properties unique to PublicPatient go here

        public PublicPatient(string insurance, string name, DateTime dob, string sex)
            : base(name, dob, sex)
        {
            InsuranceCompany = insurance;
        }

        public string InsuranceCompany { set; get; }
    }

    public class PrivatePatient : Patient
    {
        // fields, methods, properties unique to PrivatePatient go here

        public PrivatePatient(string billTo, string name, DateTime dob, string sex)
            : base(name, dob, sex)
        {
            BillingAddress = billTo;
        }

        public string BillingAddress { set; get; }
    }
}

Keep in mind that an Abstract Class, in contrast to an Interface, can optionally implement methods, fields, properties.

I only saw DamithSL's solution after I had posted mine, and I think you can learn a lot more from his example than you can from mine. I encourage you to accept his solution !

please note the change in the code in my solution (above) to:

Patient_ID = Guid.NewGuid();

use base class as Patient and derive two classes from this base class called public and private patient.
You better read Introduction to inheritance, polymorphism in C#[^]

C#

public abstract class Patient
{
    //define your fields, make them potected if you need to access by sub classes  ( no need to have patient type field)
    //    protected Doctor assignedDoctor; // Doctor assigned to Patient
    //    protected static int pIdNo = 100000; // No get and set methods - internal use only
    //    protected String name;
    //    protected int age;
    // so on.....

    // define your constructors ( you don't need patient type as input)
    //create common methods whiich not depend on pationt types, like your SetIdentifier method
    //create abstract methods which depend on patient type
    public abstract bool AssignDoctor(ArrayList listOfDoctors);
    public abstract void Mv();
}

public class PublicPatient : Patient
{

    public override bool AssignDoctor(ArrayList listOfDoctors)
    {
        // impliment PublicPatient AssignDoctor
    }

    public override void Mv()
    {
        // impliment PublicPatient Mv
    }

    public override String ToString()
    {
        // impliment PublicPatient ToString
    }
}

// do the same for PrivatePatient  sub class

I have Patient class and I am trying to create different classes for public patient and private patient, how to make all the classes work together?
