Not Covered on Medicare Denial Guide — Barley

Medicare Benefit Limit Reached: What to Do Next

Thu, 26 Mar 2026 00:00:00 +0000

What This Means

Your notice carries one of two codes, and which one it is decides whether the coverage comes back: CARC code CO-119, “Benefit maximum for this time period or occurrence has been reached,” or CO-35, “Lifetime benefit maximum has been reached.” A CO-119 maximum is tied to a time period or occurrence, so it can start fresh when a new one begins; a CO-35 lifetime maximum does not renew. Either way, this does not mean the care was unnecessary — it means you have used all the coverage Medicare provides for this service.

Medicare Denied a Free Preventive Service

Thu, 26 Mar 2026 00:00:00 +0000

What This Means

Medicare covers many preventive services — like screenings, vaccines, and your annual wellness visit — at no cost to you, as long as you see a provider who accepts Medicare assignment. If you were denied coverage or charged money for a service you believe should have been free, something may have gone wrong with how it was billed.

A claim denial or unexpected charge may reflect a coding mistake, a screening that converted to treatment, a separate service, or a coverage rule. Check the code and your medical record before assuming the charge is wrong. On a denial notice you may see CARC 96 (non-covered charges).

Medicare Denied Claim: Covered Under Different Part

Thu, 26 Mar 2026 00:00:00 +0000

What This Means

Medicare did not deny the service itself. Instead, the claim was submitted to the wrong part of Medicare. The service may be fully covered — it just needs to be billed to the correct place. On your notice this usually appears as CARC code CO-109, “claim/service not covered by this payer/contractor; you must send the claim/service to the correct payer/contractor,” or, when the service should have gone to your Medicare Advantage plan, CO-24, “charges are covered under a capitation agreement/managed care plan.”

Medicare Denied Claim: Wrong Care Setting

Thu, 26 Mar 2026 00:00:00 +0000

What This Means

Medicare denied your claim because the service was provided in a location or care setting that doesn’t match Medicare’s requirements for that type of service. On your MSN or EOB this typically appears as CARC CO-5 (procedure code inconsistent with the place of service) or CO-58 (treatment rendered in an inappropriate or invalid place of service). Medicare has specific rules about where certain procedures and treatments can be performed in order to be covered.

Medicare Denied Your DME — Appeal Guide & Checklist

Thu, 26 Mar 2026 00:00:00 +0000

What This Means

A durable medical equipment (DME) denial almost always turns on one of Medicare’s three conditions of payment: a standard written order from your treating practitioner, a face-to-face visit within the 6 months before that order for items on CMS’s required list (power wheelchairs and scooters, hospital beds, oxygen equipment, and many braces), and medical records that show the item meets Medicare’s coverage test (42 CFR 410.38). Act now: call the supplier and ask exactly which requirement the denial cites, then have your doctor’s office send the missing order, visit note, or records with your appeal — within 120 days of receiving your Medicare Summary Notice (MSN) for Original Medicare (receipt is presumed 5 days after the date on it, 42 CFR 405.942(a)) or 65 days from the date on your denial notice for Medicare Advantage.

Medicare Drug Plan Won't Cover Your Medication

Thu, 26 Mar 2026 00:00:00 +0000

What This Means

Your Medicare Part D plan is refusing to cover this drug either because it is not on the plan’s formulary — the plan’s own list of covered drugs — or because a formulary restriction (prior authorization, step therapy, or a quantity limit) has not been met. The fix for both runs through a formulary exception: your prescriber sends the plan a supporting statement explaining why the covered alternatives would be less effective for you or would cause adverse effects, and the plan must decide within 72 hours of receiving that statement — 24 hours if your prescriber tells the plan that waiting could put your health at serious risk (CMS exception rules). Do one thing now: call your prescriber’s office and ask them to submit an exception request with that supporting statement — the plan’s decision clock does not start until it arrives.

Medicare Says Another Insurance Should Pay First

Thu, 26 Mar 2026 00:00:00 +0000

What This Means

Medicare’s response indicates that another insurer may be responsible before Medicare pays. First check which coverage applied to this service on the date you received it. Under Medicare Secondary Payer rules, having other insurance does not always mean that insurance pays first.

X12 reason code 22 identifies possible coverage by another payer; code 20 identifies liability-insurance coverage for an injury or illness. Ask the billing office to explain the full response, including any remark codes. These codes alone do not establish what you owe.

Medicare Says This Service Is Not Covered

Thu, 26 Mar 2026 00:00:00 +0000

What This Means

Medicare reviewed your claim and determined that the service you received is not a covered benefit. This means Medicare will not pay for it.

There is an important difference between two types of non-covered services:

Blanket exclusions: Some services are excluded from Medicare by law, such as routine dental care, most vision and hearing services, cosmetic surgery, and long-term custodial care (Medicare.gov: what’s not covered). These generally cannot be appealed. However, some exclusions now have exceptions — for example, weight-loss drugs (Wegovy, Zepbound) were previously excluded but are now covered through the Medicare GLP-1 Bridge program starting July 2026.
Situational denials: Some services are covered only in certain circumstances. For example, a service might be covered for one diagnosis but not another, or it might require specific conditions to be met. These denials may be worth appealing.

Why This Happens

The service falls under a statutory exclusion. Medicare law specifically lists certain services it does not cover, including routine dental, vision, hearing aids, and cosmetic procedures.
The diagnosis doesn’t match coverage requirements. Medicare may cover a service for certain conditions but not others. The diagnosis codes on your claim may not have triggered coverage.
The service was coded incorrectly. Sometimes a covered service is billed with the wrong code, making it appear non-covered. A billing correction could resolve this.
A newer treatment isn’t recognized yet. Medicare may not yet have a coverage determination for newer procedures or technologies.

Should You Appeal?

Appeal outlook: Mixed

Whether an appeal makes sense depends on the type of non-covered service:
