To Resolve This Error:
Solution 1: Try to rebuild Indexes and 
ANALYZE TABLE Table_Name VALIDATE STRUCTURE;

Solution 2:  Still You are getting the same Error...
Try this..   
BEGIN
            DBMS_REPAIR.SKIP_CORRUPT_BLOCKS
                 ( SCHEMA_NAME => 'SCOTT', OBJECT_NAME => 'DEPT',
                   OBJECT_TYPE => dbms_repair.table_object, 
                    FLAGS => dbms_repair.skip_flag);
 END;

Check this Query:
              SELECT OWNER, TABLE_NAME, SKIP_CORRUPT FROM DBA_TABLES WHERE OWNER = 'SCOTT'; 

OWNER	TABLE_NAME	SKIP_COR
SCOTT	ACCOUNT	DISABLED
SCOTT	BONUS	DISABLED
SCOTT	DEPT	ENABLED

 Create a Backup table same as this table.

• Then take the backup into backup table and drop the original.
• Rename backup to original.
• If the table is very big use Bulk collect to take backup.
• Run statistics for New Table.
