ATCM 93120 Phase 2 is a specific billing code for remote patient monitoring that doctors use when they check on your health data between office visits

ATCM 93120 Phase 2 refers to a medical billing code — specifically, it's part of the remote patient monitoring (RPM) system that Medicare and insurance companies use to pay doctors for watching your health information from a distance. The "93120" is the code itself, and "Phase 2" means this is the second tier of monitoring intensity, used when a patient needs more frequent check-ins than the basic level.

If your doctor has enrolled you in remote monitoring, they're collecting data from devices you use at home — things like blood pressure cuffs, glucose monitors, or weight scales — and reviewing that information regularly. Phase 2 means your doctor is spending more time on your care than Phase 1 would require, so the billing reflects that additional work.

Key Takeaways

  • ATCM 93120 Phase 2 is a billing code that lets doctors get paid for monitoring your health data from home devices between office visits.
  • Phase 2 is used when you need more frequent monitoring than Phase 1, typically for conditions that require closer watching.
  • Your insurance or Medicare covers the cost of the monitoring service itself, though your out-of-pocket costs depend on your specific plan.
  • You'll need a device that connects to the monitoring system — your doctor's office will tell you which one and how to use it.
  • The monitoring happens continuously, but your doctor reviews the data on a schedule and contacts you if something needs attention.

How Phase 2 monitoring differs from Phase 1

Phase 1 remote monitoring is the entry level — it's used when a patient needs basic oversight of one or two conditions. Phase 2 steps up the intensity. Your doctor is expected to review your data more often, spend more time analyzing it, and be more ready to adjust your treatment if the numbers show a problem.

The difference matters mainly to your doctor's billing. To you, it often means you're checking in more frequently or your condition is more complex. If you have multiple chronic conditions or one that's newly diagnosed and unstable, Phase 2 is more likely to be the right fit.

What devices and data are involved in Phase 2

The devices depend on what your doctor is monitoring. Common ones include blood pressure monitors, pulse oximeters (which measure oxygen levels), weight scales, glucose meters for diabetes, and heart rhythm monitors. Some devices sync automatically to your doctor's system; others require you to enter readings manually through an app or website.

Your doctor's office will provide the device or tell you which one to buy and how to set it up. They'll also give you instructions on how often to take readings — this might be daily, several times a day, or on a specific schedule. The data flows to your doctor's monitoring system, where it sits until they review it according to their schedule.

Who pays for Phase 2 remote monitoring

Medicare covers ATCM 93120 Phase 2 as long as your doctor is enrolled in the program and you meet the medical criteria. Most private insurance plans cover it too, though coverage varies by plan. Your out-of-pocket cost — if any — depends on your deductible, copay structure, and whether your plan has already met your deductible for the year.

The device itself may or may not be covered. Some insurance plans pay for it; others expect you to buy it. Ask your doctor's office before you start monitoring — they usually know what your plan covers and can tell you upfront whether you'll have a cost.

How often your doctor reviews your data in Phase 2

There's no single schedule — it depends on your condition and your doctor's protocol. Some practices review Phase 2 data daily; others do it several times a week. Your doctor is supposed to be more responsive in Phase 2 than Phase 1, which is why the billing code is different.

You won't necessarily hear from your doctor every time they look at your data. Most practices only contact you if something is outside the normal range or if a trend concerns them. If your readings are stable and expected, you might not hear anything for weeks, which is actually a good sign — it means your condition is under control.

What happens if your data shows a problem

When your doctor or their staff sees a reading that's too high, too low, or trending the wrong way, they'll reach out. This might be a phone call, a message through your patient portal, or a text, depending on how urgent the situation is. They may ask you to take another reading, adjust your medication, change your diet or activity, or come in for an office visit.

In a true emergency — like a dangerously high blood pressure or a heart rhythm problem — they should contact you right away. For less urgent issues, you might get a call within a business day or two. Make sure your doctor's office has your correct phone number and knows the best way to reach you.

How to get your free guide with Phase 2 monitoring

Your doctor has to order it — you can't start on your own. If you have a chronic condition that might benefit from remote monitoring, ask your doctor whether Phase 2 makes sense for you. They'll assess whether you meet the medical criteria and whether you're comfortable using the devices.

Once your doctor orders it, their office will handle the enrollment with your insurance and set you up with the device. They'll show you how to use it, explain how often to take readings, and tell you what to do if you have questions. The whole setup usually takes a week or two from the time your doctor places the order.

Frequently Asked Questions

Do I have to pay anything out of pocket for Phase 2 monitoring?

That depends on your insurance plan. Medicare covers it, and most private plans do too, but you may have a copay or coinsurance. The device itself may or may not be covered — ask your doctor's office before you start. They can tell you what your plan covers and what you might owe.

What if I don't want to do remote monitoring?

You can decline. Remote monitoring is optional, and your doctor can't force you into it. If you prefer to manage your condition with office visits only, that's your choice. Just let your doctor know so they can plan your care accordingly.

Can Phase 2 monitoring replace my office visits?

No. Remote monitoring is meant to work alongside office visits, not replace them. You'll still see your doctor in person on whatever schedule they recommend. Phase 2 just gives them more information between those visits so they can catch problems earlier.

What if the device stops working or I can't use it?

Tell your doctor's office right away. They can troubleshoot the problem, send you a replacement device, or switch you to a different type of monitoring. Don't just stop taking readings — let them know what's happening so they can adjust your care plan.

How long will I be on Phase 2 monitoring?

That depends on your condition. Some people stay on it long-term; others move to Phase 1 or stop monitoring once their condition is stable. Your doctor will review whether you still need Phase 2 at your office visits and adjust as needed.
