Answer 1

If you are able to put there also order discriminator, it could seems like this: (I consider also fact that there can be more DUE/DEPOSITS for one PATIENT_NBR)

IF OBJECT_ID('tempdb..#Patient_ledger') IS NOT NULL DROP TABLE #Patient_ledger
    CREATE TABLE #Patient_ledger 
    (ID INT IDENTITY, 
     PATIENT_NAME varchar(250),
     PATIENT_NBR bigint,
     BILLNO varchar(250),
     BILLAMOUNT bigint,
     PAID_AMOUNT bigint)

Insert into #Patient_ledger (PATIENT_NAME ,PATIENT_NBR ,BILLNO ,BILLAMOUNT ,
PAID_AMOUNT )

select 'ABC',1,'DUE_BILL_ABC_1',100,50
union all
select 'ABC',1,'DUE_BILL_ABC_2',160,90
UNION ALL
select 'ABC',1,'DEPOSIT_BILL_ABC',0,40
UNION ALL
select 'XYZ',2,'DEPOSIT_BILL_XYZ',0,70
UNION ALL
select 'XYZ',2,'DUE_BILL_XYZ_1',100,30


;WITH CTE AS (
SELECT PATIENT_NBR, 
       BILLNO,
       PAID_AMOUNT,
       BILLAMOUNT,
       BILLAMOUNT-PAID_AMOUNT AS BALANCE, 
       ROW_NUMBER() OVER (PARTITION BY PATIENT_NBR ORDER BY ID) AS RN
FROM #Patient_ledger)

SELECT a.PATIENT_NBR,
       a.BILLNO,
       a.BILLAMOUNT,
       a.PAID_AMOUNT,
       CASE WHEN ISNULL(LAG(a.BALANCE + ISNULL(x.ADDS,0)) OVER (PARTITION BY a.PATIENT_NBR ORDER BY a.RN),0) + a.BILLAMOUNT - a.PAID_AMOUNT < 0 
            THEN 0
            ELSE a.BALANCE + ISNULL(x.ADDS,0)
       END AS FINAL_BALANCE

FROM CTE a
CROSS APPLY (SELECT SUM(BALANCE) AS ADDS 
                FROM CTE f 
                    WHERE f.PATIENT_NBR = a.PATIENT_NBR AND f.RN < a.RN) x
