His Back Pain Persisted for 6 Months. Medicare Will Cover the Care, but He Still Owes 20%.

A 68-year-old man walks into his primary care office after six months of low back pain. His doctor mentions an option he did not know Medicare offered: ongoing chronic pain management, including regular visits to assess the pain, adjust treatment and coordinate care. He hears the word “covered” and relaxes somewhat.

Medicare Part B does cover qualifying chronic pain management for persistent or recurring pain lasting longer than three months. But covered is not the same as free. After the annual deductible, the patient generally owes 20% of the Medicare-approved amount each time covered Part B care is delivered. For someone whose back problem turns into months of appointments, imaging, physical therapy or injections, those percentages can begin stacking up.

Three Months Opens the Door

Medicare’s chronic pain management benefit applies when pain has persisted or recurred for more than three months. The covered services can include an assessment, medication management, development or revision of a care plan and coordination with other providers. The goal is not simply another office visit. It is to give patients with long-running pain a more organized way to manage it.

At six months, the patient in this case is well beyond the time threshold. That is the useful part of the rule. The less obvious part is how Medicare shares the bill. In 2026, the Medicare Part B deductible is $283. Once that has been met, Original Medicare generally pays 80% of the approved amount for covered Part B services and leaves the remaining 20% to the beneficiary. The deductible is annual. The coinsurance is not. If another covered service is billed the following month, another 20% share can follow.

The Monthly Visit Is Only Part of the Exposure

The chronic pain management visit itself may not be the bill that breaks the budget. The larger issue is what can gather around it. A persistent back problem may eventually involve a specialist, an MRI, physical therapy, injections or other outpatient treatment. Under Original Medicare, many of those services bring their own Part B cost sharing after the deductible.

There is no overall annual out-of-pocket maximum built into Original Medicare. That means someone can spend months moving through a perfectly reasonable treatment plan while continuing to pick up a share of each covered service. The distinction matters because “Medicare covers chronic pain management” sounds like a single new benefit. In practice, the monthly care plan can become the center of a much wider collection of Part B services. (Recurring coinsurance is one of several Medicare cost traps we mapped in a free guide here: Medicare’s Hidden Bills.)

Supplemental Coverage Changes the Math

Someone with Medigap Plan G faces a very different version of the same treatment year. After the Part B deductible is met, Plan G generally covers the Part B coinsurance that Original Medicare leaves behind. Medicare Advantage works differently again. Plans have an annual in-network out-of-pocket limit for covered Part A and Part B services, but the copays, networks and authorization rules depend on the individual policy.

That makes the pain diagnosis only half of the financial equation. The other half is what kind of coverage sits behind Medicare when the treatment plan begins expanding.

Before the Next Appointment, Put the Treatment Plan on Paper

Before months of care begin accumulating one service at a time, these three steps can make the likely cost much easier to see:

1. Ask what the monthly chronic pain management visit is expected to cost under Medicare and what your estimated share will be after the deductible.
2. See what else the doctor expects the plan to involve over the next several months, including imaging, specialists, therapy or injections, so those costs do not arrive as separate surprises.
3. Check what supplemental coverage you already have. If you use Medicare Advantage, confirm the relevant doctors and facilities are in network and review the plan’s cost sharing before scheduling additional services.

He walked into the office because six months of back pain had become too much to ignore. Medicare can help him manage what comes next, but the 20% share is worth seeing clearly before the visits start piling up.
