How long do I have to appeal?

It depends on your coverage: 180 days for most employer and marketplace plans, 120 days for Original Medicare, about 90 days for Medicaid (varies by state), and only 65 days for Medicare Advantage. Set your deadline clock before you do anything else.

Denial code 193: what it means — and how to fight it

Denial code 193 (shown on your EOB as CO-193 or PR-193) means: “Original payment decision is being maintained. Upon review, it was determined that this claim was processed properly.” In plain English: They looked again and kept the same answer. That doesn't end it — you can still take it to the next appeal level, including outside review.
