Msg 156, Level 15, State 1, Line 26
Incorrect syntax near the keyword 'left'.
Query:

inner join rrscsql2.arhighdollar.dbo.tblPatInfoHistory p
on a.patID=p.patID and a.LogID=p.LogID

You have to introduce all of your CTEs first via a single WITH, and then you can use them in a final query:
with Cte_LatestPatInfo as
(select max(a.LogID) as LastPatRec, p.unitnum, p.PatNum, a.iplan from
rrscsql2.arhighdollar.dbo.tblarinfoHistory a
inner join rrscsql2.arhighdollar.dbo.tblPatInfoHistory p
on a.patID=p.patID and a.LogID=p.LogID
where a.Active = 1
and a.ReasonCode is not null
group by p.unitnum, p.PatNum, a.iplan),
cte_EOMDenials as
(select d.* from rrscsql2.Denials.dbo.tblDenialMonthEnd d
Inner join rrscsql3.Facilities.dbo.vwFacilities f
on d.UnitNum = f.UnitNum and f.Owner like '%LifePoint%'
Inner join rrscsql2.Denials.dbo.tblDispositionDictionary t
on d.disposition=t.disposition and DispositionType like'O%'
Where datediff(mm, monthending, GETDATE()) = 1
and DATEDIFF(mm,DischDate,monthending)>2)
select *,rc.Description from rrscsql2.arhighdollar.dbo.tblPatInfoHistory p
inner join cte_LatestPatInfo li
on p.PatNum=li.PatNum and p.UnitNum=li.UnitNum and p.LogID = li.LastPatRec
inner join rrscsql2.arhighdollar.dbo.tblarinfoHistory ah
on ah.LogID=p.LogID and ah.iplan = li.iplan and p.PatID=ah.PatID
left join rrscsql2.ARHighDollar.dbo.tblReasonCodes rc
on ah.ReasonCode=rc.ReasonCode
left join cte_EOMDenials d
on p.unitnum=d.unitnum and p.patnum = d.patnum and p.insplan=d.iplan

The statement does not seem to join two CTEs. If you want to join two ctes you can achieve it like the following example
;WITH CTE_1
as
( select field1, field2... from sometable),
CTE_2
as
(select field1, field2... from sometable),
select a.field1, a.field2, b.field1, b.field2
from CTE_1 a left join CTE_2 b on a.field1 = b.field1;
You will notice that the two ctes were defined first, separated by comma(,) then use in the select statement.
