Match any action in custom route

Question

I need to create a custom route map that allows me to match any action in a certain url mapping. Example: www.site.com/patient/records/treatments/23 where treatments could be any action in the pacient controller.

Here's what i have try but doesnt work:

  routes.MapRoute("records_ho", "{controller}/records/{action}/{recordid}", new {
            controller = "patient", recordid = UrlParameter.Optional
        });

  routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Account", action = "User", id = UrlParameter.Optional }
            );

As you may have notice, i did not specify the action property in 'records_ho' and thats because I would like to avoid specifing in the MapRoute the 15 actions defined in the controller Pacient.

How can i achieve that?

Update: Here is the action

[HttpGet]
public ActionResult Treatments(string recordid)
{
    // some code here...


    return View(model);
}

In theory everything should be working as expected, see below.

Code of the routing:

using System.Web.Mvc;
using System.Web.Routing;

namespace WebApplication6
{
    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.MapRoute(
                name: "Default",
                url: "{controller}/records/{action}/{recordid}",
                defaults: new { controller = "patient", recordid = UrlParameter.Optional }
            );
        }
    }
}

Code of the controller:

using System.Web.Mvc;

namespace WebApplication6.Controllers
{
    public class PatientController : Controller
    {
        [HttpGet]
        public ActionResult Treatments(string recordid)
        {
            return View();
        }
    }
}

And the request/response:

Request URL:http://localhost:29930/patient/records/treatments/23
