How to use bitwise operator in existing sql query? - sql

Question

Here is my sql query. I have column name "ExpenseBucketCoverage" in claim table in which I am storing bitwise operators store multiple values in one column like below
MED_COPAY = 1, MED_DED= 10, MED_COINS = 100, RX_COPAY = 1, RX_DED= 10, RX_COINS = 100
I want to replace hard coded value like MED_COPAY, MED_COINS, MED_DED, RX_DED, RX_COINS & RX_COPAY in query by using ExpenseBucketCoverage column value. Can some one please tell me how can I do that?
Someone has suggested me below soultion
retrieve data from claim and left joining the first matched record in eligibility. And then add custom code to loop through the datarows to split the rows by covered expense bucket, and set the service category code in-memory column based on the ExpenseBucketCoverage value for the claim.
SELECT
e.categoryid,
c.servicetype,
'II' AS RepordType,
e.TPAId AS TPA_Id,
e.EmployerCode,
e.SubscriberId,
e.MemberID,
c.ServiceFrom,
c.ServiceTo,
CASE
WHEN e.categoryid IN( 'MED_DED', 'RX_DED' ) THEN
deductible
WHEN e.categoryid IN( 'MED_COINS', 'RX_COINS' ) THEN
isnull(coins,0)
WHEN e.categoryid IN( 'MED_COPAY', 'RX_COPAY' ) THEN
copay
ELSE 0
END AS ClaimAmount,
'' AS AccountTypeCode,
'1' ClaimsCrossoverAutoPay,
e.CategoryId,
CASE c.ServiceType
WHEN 'H' THEN
CASE e.PayeeIndicator
WHEN 'N' THEN '0'
WHEN 'Y' THEN '1'
END
WHEN 'P' THEN '0'
END AS PayProvider,
CASE c.ServiceType
WHEN 'H' THEN
CASE PayeeIndicator
WHEN 'N' THEN '0'
WHEN 'Y' THEN '1'
END
WHEN 'P' THEN '0'
END AS ReimbursementMethod,
CASE c.ServiceType

END AS ProviderId,

c.ClaimNumber + e.CategoryId as 'ExternalClaimNumber',
