insert into values with where clause

I am trying to programmatically enter values into my table.

I cannot use a straight Select @variables. I have to use the keyword Values.

How can I create a where clause when using Values in the insert into.

I am trying to avoid duplicates

  DECLARE @MyID INT
  DECLARE @Phone varchar(10)
  DECLARE @MyDATE DateTime
  DECLARE @Agent as varchar(50)
  DECLARE @Charge as varchar(50)
  DECLARE @Vendor as varchar(50)

  SET @MyID = 215199999
  SET @Phone = '9999999999'
  SET @MyDATE = '2010-12-04 11:56:12.000'
  SET @Agent = 'fbrown'
  SET @Charge = 'NO'
  SET @Vendor = 'NO'

  INSERT INTO [MyDB].[dbo].[Accounts]
  (MyID,Phone,MyDate,Agent,Charge,Vendor)
  VALUES (
  @MyID
  ,@Phone
  ,@MyDATE
  ,@Agent
  ,@Charge
  ,@Vendor 
  ) WHERE MyID NOT IN (@MyID)

Answer

IF NOT EXISTS(SELECT 1 FROM [MyDB].[dbo].[Accounts] WHERE MyID = @MyID)
    INSERT INTO [MyDB].[dbo].[Accounts]
        (MyID, Phone, MyDate, Agent, Charge, Vendor)
        VALUES 
        (@MyID, @Phone, @MyDATE, @Agent, @Charge, @Vendor)
