The Appeal Clock Started the Day the Denial Posted. Most DME Teams Find Out Too Late
Medicare gives you 120 days to ask for a redetermination. That sounds like plenty until the denial sits in a work queue for a month and the proof of delivery turns out to be in someone's email.
Check this today: open your oldest unworked Medicare denial and count the days since the remittance date. If it is past day 90, you are no longer planning an appeal. You are racing one.
A denial is a decision, not a verdict
Picture a Tuesday morning. A billing lead pulls up a denied CPAP claim from late summer. The reason code points to missing documentation. She's pretty sure the sleep study and the signed order are somewhere in the patient file, so she asks intake to dig them out. Intake finds the order. The proof of delivery is a photo on a driver's phone. By the time all of it is in one place, the date on the remittance advice is six weeks old.
Nothing about that story is unusual. Medicare denials are appealable, and a meaningful share of them are overturned when the right records get in front of a reviewer. The trouble is the calendar. The appeal process is a ladder with a hard deadline on every rung, and the first rung is the one suppliers miss most.
"The denial didn't cost you the claim. The week it sat in a queue did."
The ladder, in plain terms
Original Medicare has five appeal levels. Most DME disputes get settled in the first two or three, so those are the ones worth building a routine around.
Those windows are counted from when you receive the notice, and Medicare presumes you received it five days after the date printed on it. Don't lean on that cushion. Treat the remittance date as day one and you'll never be surprised.
| Level | Who decides | Filing window | Where suppliers stumble |
|---|---|---|---|
| 1. Redetermination | The DME MAC | 120 days from the initial determination | Highest riskLate filing, one form covering several claims, no supporting records attached |
| 2. Reconsideration | Qualified Independent Contractor (QIC) | 180 days from the redetermination notice | HighNew evidence arrives without an explanation of why it wasn't submitted earlier |
| 3. ALJ hearing | Administrative Law Judge | 60 days from the QIC decision | ModerateClaim value falls under the minimum amount in controversy, which CMS adjusts every year |
| 4–5. Council and federal court | Departmental Appeals Board, then a federal judge | Set by notice at each level | RareSeldom worth it for a single DME claim |
Two details trip people up. First, the redetermination request is not a corrected claim. If the denial came from a typo in a modifier or a wrong date, a clerical-error reopening is often faster than a full appeal, and it has its own window (generally one year from the initial determination). Second, some rejections can't be appealed at all. Claims that come back unprocessable, such as those carrying remark code MA130, need to be fixed and resubmitted as new claims.
What a slow appeal really costs
Suppliers tend to count the cost of an appeal as staff time. That's the smaller number. The bigger one is the claims that never get appealed because the window closed while everyone assumed someone else had it.
Run it on a modest month. Say your team sees 60 Medicare denials, and 20 of them are the kind a good record would overturn. If even a quarter of those age out before anyone files, that's five paid claims written off for no reason other than timing. At an average DMEPOS claim of a few hundred dollars, you lose real money, and you also keep the same upstream gap that caused the denial in the first place.
There's a quieter cost, too. Each overturned denial is a lesson about what the original submission lacked. Teams that file late don't get the lesson, because they never open the file.
The timeline most teams don't draw
Put the dates on a single line and the pressure points show up fast. The longest stretch of the process is the one you control the least, which is why the first 30 days matter so much.
What a reviewer actually wants to see
A redetermination is a paper review. Nobody calls to ask what you meant. If the record doesn't answer the denial reason on its face, the denial stands. In practice that means the strongest appeals do three things: they answer the specific reason code, they include only legible records, and they tell the reviewer where to look.
Handwritten notes that can't be read get set aside. A signature log without the matching page gets set aside. A twelve-page fax with the one relevant page buried at the end gets skimmed. Short and indexed beats thorough and unsorted.
"An appeal packet is a cover letter plus proof. The reviewer shouldn't have to hunt for the proof."
Fix the file before the file needs fixing
Every item on that checklist is something intake could have confirmed on the day the order arrived. That's the uncomfortable pattern in most appeal work: the evidence existed, and it just wasn't attached to the right claim at the right moment. Teams that track their appeal win rate by denial reason often find that the same three or four codes account for most of their volume. Those codes are a map of where intake is leaking.
Start small. Pick the top denial reason from the last quarter, pull ten of those files, and ask where the missing document should have been caught. You'll probably land on a handoff rather than a person.
1. Put the deadline in the denial queue, not in someone's head
Add a "days remaining" column and sort by it. A queue ordered by dollar value hides the claim that's about to expire.
2. Build the packet as claims arrive, not as they deny
If proof of delivery and the signed order are indexed to the claim at intake, an appeal is a ten-minute job instead of a two-day scavenger hunt.
3. Review overturned appeals once a month
Each win tells you what the original submission was missing. Feed that back to intake as a rule, not a reminder email.
