Create this function in your database:

USE [YourDatabase]
GO

/****** Object:  UserDefinedFunction [dbo].[SplitListToTable]    Script Date: 5/21/2018 8:13:29 AM ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE FUNCTION [dbo].[SplitListToTable]
    (
      @List NVARCHAR(2000) ,
      @SplitOn NVARCHAR(5)
    )
RETURNS @RtnValue TABLE
    (
      Id INT IDENTITY(1, 1) ,
      Value NVARCHAR(100)
    )
AS
    BEGIN
        WHILE ( CHARINDEX(@SplitOn, @List) > 0 )
            BEGIN 
                INSERT  INTO @RtnValue
                        ( Value
                        )
                        SELECT  Value = LTRIM(RTRIM(SUBSTRING(@List, 1, CHARINDEX(@SplitOn, @List) - 1))); 
                SET @List = SUBSTRING(@List, CHARINDEX(@SplitOn, @List) + LEN(@SplitOn), LEN(@List));
            END; 

        INSERT  INTO @RtnValue
                ( Value )
                SELECT  Value = LTRIM(RTRIM(@List));
        RETURN;
    END;



GO

Then you can parse your parameter like this:

SELECT *
FROM YourDatabase.dbo.YourTable
WHERE YourColumn IN(SELECT value FROM dbo.SplitListToTable(@YourParameter, ','))
