To reduce CPU cost being used by SORT

We are using a query and in its execution plan it utilizes 182% CPU cost while performing a sort. Please advice on how to reduce it. query structure: SELECT DISTINCT'Dupility' as Rery_Cls,'LINE' Rery_Tpe,b.clpe, b.Check_Ref_ID, min(a.claim_id) oriim,convert(varchar,getdate(),101) Load_Date,c.year_month_num load_month,0 as include_flag, 0 as isreviewedfrom DBO.PR_PaieDups a with(nolock, index(PR_PaidCls1))join DBO.PR_Paps b with(nolock, index(PR_Paups1))on a.subscriber_id = b.subscriber_id--Subscriberjoin dw.dbo.date c with(nolock) on convert(varchar,getdate(),101) = convert(varchar,c.date_id,101)left outer join CIes z on b.claim_id = z.claim_nbr and z.recovery_class = 'Dupllity'left outer join tbl_ble1 y on b.claid = y.claim_nbr and y.re_css = 'Dupllity'where a.from_date = b.from_date--From Date (DOS)and a.se_id = b.seer_id--Provider IDand a.billed_amount = b.billed_amount--Billed Amountand a.procode = b.procde--Proc Codeand a.tos = b.tos--TOSand a.rede = b.revode--Rev Codeand a.pos = b.pos--POSand a.mod_1 = '' and b.mod_1 = ''--null modifiersand a.mod_2 = '' and b.mod_2 = ''and a.mod_3 = '' and b.mod_3 = '' and a.mod_4 = '' and b.mod_4 = ''and a.root_claim_id < b.root_claim_id--original claim ID is less than the duplim IDand b.claicd = 'H'--Facility Claimsand b.pait > 0and a.claidate

See what happens if you remove all or some of the WITH query hints.

Thank you. We cheked but though the RID look up decreased by 1%, the sort which is taking 182% CPU, still remains the same.
