Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE claims_processing_stages ( claim_status_name VARCHAR, claim_stage_id VARCHAR )
TABLE: CREATE TABLE claims_processing ( claim_stage_id VARCHAR )

### Question ###
What is the name of the claim processing stage that most of the claims are on?

### Accurate SQL ###

SELECT t2.claim_status_name FROM claims_processing AS t1 JOIN claims_processing_stages AS t2 ON t1.claim_stage_id = t2.claim_stage_id GROUP BY t1.claim_stage_id ORDER BY COUNT(*) DESC LIMIT 1
