How about something like
SELECT
ORD.Name,OUD.UserDataCode,
CASE WHEN OUD.UserDataCode = 'RX_BridgingMedicationName' THEN OUD.Value ELSE NULL END [Medication Name]
CASE WHEN OUD.UserDataCode = 'RX_Bridgingreason' THEN OUD.Value ELSE NULL END [Bridging Reason]
FROM CV3ORDER ORD
JOIN CV3OrderUserData OUD ON OUD.OrderGUID = Ord.GUID
AND OUD.ClientGUID = Ord.ClientGUID
