SQL & PL/SQL :: Rank / DECODE Most Popular / Most Used Term

I have this code which simply gives me the count of term.

SELECT
OUA_ID

,COALESCE (MAX( DECODE( TERM, 0603, TERM_COUNT, NULL ) ), 0 ) "TERM_0603_CNT"
,COALESCE (MAX( DECODE( TERM, 0702, TERM_COUNT, NULL) ), 0 ) "TERM_0702_CNT"
,COALESCE (MAX( DECODE( TERM, 0705, TERM_COUNT, NULL ) ), 0 ) "TERM_0705_CNT"
,COALESCE (MAX( DECODE( TERM, 0707, TERM_COUNT, NULL ) ), 0 ) "TERM_0707_CNT"

FROM(

SELECT DISTINCT
OUA_ID, TERM_COUNT, TERM
FROM(
SELECT OUA_ID, TERM ,PROVIDER_CDE, COUNT(*) TERM_COUNT
FROM TABLE
WHERE PROVIDER_CDE = 'BILL'
GROUP BY OUA_ID, TERM, PROVIDER_CDE)) GROUP BY OUA_ID

Gives:

OUA_IDTERM_0603_CNTTERM_0702_CNTTERM_0705_CNTTERM_0707_CNT
32710 0 3 7 0
45726 2 0 1 0

Is there a way i could used the rank function (with decode) to only display the 1ST (First) and 2nd(Second) most used term per OUA_ID?

So i get this:

OUA_ID1st MOST USED2nd MOST USED
3271 705 702
45726 603 705
