Try this and tell me if it work with other sample data too.

create table #Patient_ledger (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


SELECT PATIENT_NBR PATIENT_NUMBER
    ,BILLNO
    ,BILLAMOUNT
    ,PAID_AMOUNT
    ,CASE 
        WHEN billamount = 0
            AND lag((BILLAMOUNT - PAID_AMOUNT), 1, 0) OVER (
                PARTITION BY PATIENT_NBR ORDER BY PATIENT_NBR
                ) = 0
            THEN 0
        ELSE SUM((BILLAMOUNT - PAID_AMOUNT)) OVER (
                PARTITION BY PATIENT_NBR ORDER BY PATIENT_NBR ROWS UNBOUNDED PRECEDING
                )
        END Balance
FROM #Patient_ledger

Drop table #Patient_ledger
