Managing Diabetes at Home
Whether you or a loved one was just diagnosed or have been managing diabetes for years, having the right equipment makes a real difference. This guide covers every device and supply you might need — what it does, what Medicare covers, and how to set up effective monitoring at home.
Understanding Your Equipment Needs
Managing diabetes at home requires a small ecosystem of devices and supplies. The good news: most of them are covered in whole or in part by Medicare. The challenge is knowing what exists, what you actually need, and how to get it covered.
Type 1 vs. Type 2 — same tools, different intensity.
People with Type 1 diabetes typically need a full insulin delivery system (pump or multiple daily injections) plus continuous glucose monitoring. People with Type 2 may use oral medications, injectable medications, or insulin — and their monitoring needs vary. This guide covers all options. Your diabetes care team will help you figure out what's right for you.
The Main Categories of Diabetes Equipment
📡 Blood Sugar Monitoring
- →Continuous Glucose Monitor (CGM) — sensor under the skin reads glucose every 5 min
- →Blood Glucose Meter — traditional fingerstick device for spot checks
- →Test Strips & Lancets — consumables for the glucose meter
💉 Insulin Delivery
- →Insulin Pump — wearable device delivering a continuous insulin dose
- →Insulin Pen — pre-filled or refillable pen for injections
- →Syringes — traditional vial-and-syringe injections
👟 Foot Care
- →Therapeutic/Diabetic Shoes — extra-depth to prevent pressure sores
- →Custom Molded Inserts — redistribute pressure, reduce ulcer risk
- →Wound Care Supplies — for managing diabetic foot wounds at home
🧴 Everyday Supplies
- →Alcohol Swabs — clean skin before injections or sensor insertion
- →Sharps Container — safe disposal of needles and lancets
- →Glucose Tablets — fast-acting sugar for treating low blood sugar
📋 Before ordering anything: Talk to your doctor or diabetes educator. You need a prescription for most diabetes equipment. Getting the prescription right the first time prevents billing headaches and delays.
Equipment by Type — What to Know
Here's a deeper look at each category. You don't need all of this — your care team will recommend what's right. But knowing the options helps you have better conversations with your doctor.
Continuous Glucose Monitor (CGM)
Real-time glucose readings without fingersticksA CGM uses a tiny sensor inserted just under your skin (usually the abdomen or back of the arm) to measure glucose levels in the fluid around your cells. It sends readings to your smartphone, a small receiver, or a smartwatch every few minutes — and can alert you when glucose is too high, too low, or moving in a dangerous direction. This is a game-changer for people who have hypoglycemia unawareness (don't feel the symptoms of low blood sugar) or anyone who wants tighter glucose control.
Popular systems include the Dexcom G7, Abbott FreeStyle Libre 3, and Medtronic Guardian 4. Each uses a disposable sensor that lasts 10–15 days.
Typical cost (without insurance)
$100–$200/month for sensors + transmitter
Medicare Part B
Covers therapeutic CGMs at 80% after deductible. Sensors and transmitters included. Rx required.
What to know
Must be prescribed by a doctor. The CGM must qualify as a "therapeutic" device (not just an adjunct). Ask specifically for a therapeutic CGM prescription.
Blood Glucose Meter + Test Strips + Lancets
For spot-checking blood sugar with a fingerstickA traditional glucose meter is a small handheld device. You prick your fingertip with a lancet to get a small drop of blood, apply it to a test strip inserted into the meter, and get a reading in seconds. Even if you use a CGM, you may need a meter for calibration or backup. Meters are inexpensive — often free from the manufacturer — but test strips add up quickly.
Typical cost
Meter: often free. Test strips: $30–$100/month. Lancets: $10–$20/month.
Medicare Part B
Covers one meter + strips (300/quarter for insulin users; 100/quarter for non-insulin users). Lancets covered. Rx required.
What to know
The meter brand must be compatible with the test strips your Medicare-enrolled supplier stocks. Ask before switching brands.
Insulin Pump
Continuous automated insulin deliveryAn insulin pump is a small wearable device — about the size of a pager — that delivers insulin continuously through a thin tube (infusion set) inserted under the skin. It replaces multiple daily injections by delivering a steady background dose (basal rate) and allowing you to program doses for meals (bolus doses). Advanced systems can even auto-adjust based on CGM readings (called a "closed-loop" or "hybrid closed-loop" system). Pumps are typically for Type 1 diabetes or Type 2 patients with complex insulin needs.
Typical cost
$4,000–$8,000 for the device. Supplies (infusion sets, reservoirs): $100–$200/month.
Medicare Part B
Covers pump + supplies at 80% when deemed medically necessary. Insulin used in the pump is also covered under Part B (not Part D).
What to know
Requires detailed documentation of medical necessity from your doctor. The pump must be from a Medicare-enrolled DME supplier.
Insulin Pens & Syringes
For multiple daily injection therapyInsulin pens are pre-filled (disposable) or refillable devices that make injections easier and more precise than drawing from a vial with a syringe. You dial in your dose and press a button — no measuring required. Traditional syringes are still commonly used, especially when cost is a factor. Both approaches require insulin pen needles or syringes, which are purchased separately.
Typical cost
Pens: insulin cost varies. Needles: $15–$30/month. Syringes: $10–$20/month.
Medicare Part D
Insulin (vials or pens) and pen needles are covered under Part D. Syringes are also Part D. Not Part B (unless used in a pump).
What to know
Insulin pen needles and syringes can be purchased at any pharmacy. Check Part D formulary for insulin brand coverage.
Therapeutic (Diabetic) Shoes & Custom Inserts
Foot protection to prevent ulcers and amputationsDiabetes can reduce sensation in your feet (neuropathy) and slow wound healing — a dangerous combination. A small pressure point from an ill-fitting shoe can turn into an ulcer, then an infection, then a potential amputation. Therapeutic shoes are designed with extra depth and width to reduce pressure points. Custom inserts (orthotics) are molded to your foot shape to redistribute pressure away from vulnerable areas.
Typical cost
Shoes: $150–$400/pair. Custom inserts: $300–$600 per set.
Medicare Part B
Covers 1 pair of therapeutic shoes + 3 pairs of inserts per calendar year. Doctor must certify foot condition. 80% after deductible.
What to know
Must be fitted by a podiatrist, orthotist, prosthetist, or pedorthist. Your doctor signs the prescription form. Not all shoe stores qualify.

Medicare Coverage for Diabetes Supplies
Medicare covers more diabetes equipment than many people realize — but the rules vary by item. Here's a clear breakdown.
B What Medicare Part B Covers
Part B covers diabetes equipment and supplies as Durable Medical Equipment (DME). You pay 20% after the annual deductible. The supplier must be Medicare-enrolled and accredited.
Blood Glucose Monitors & Test Strips
Covered under the DMEPOS benefit. Quantity limits apply: up to 300 test strips + 300 lancets per 3 months for insulin users; up to 100 per 3 months for non-insulin users.
Continuous Glucose Monitors (Therapeutic CGM)
Covered when the CGM is categorized as "therapeutic" (replaces fingerstick testing). Prescription required. Sensors and transmitters covered as supplies.
Insulin Pumps + Insulin for the Pump
The pump and all supplies (infusion sets, reservoirs) are covered under Part B when medically necessary. Insulin used IN a pump is covered under Part B — not Part D.
Diabetic Shoe Benefit
1 pair of therapeutic shoes + 3 pairs of custom inserts per calendar year. Or 1 pair of shoes with built-in depth inserts if custom inserts aren't needed. Doctor must certify diabetes diagnosis + foot condition.
Insulin Pens & Syringes — NOT Part B
Regular injected insulin and injection supplies (pens, syringes, pen needles) are covered under Part D (prescription drug coverage) — NOT Part B. Exception: insulin in a pump is Part B.
C CGM Coverage Criteria (What Makes a CGM "Therapeutic")
Medicare distinguishes between two types of CGMs:
✅ Therapeutic CGM (covered)
Used to make treatment decisions (insulin dosing, meals, activity). Replaces fingerstick testing. Examples: Dexcom G7, Abbott FreeStyle Libre 3.
⚪ Adjunctive CGM (not covered under Part B)
Used as supplemental information alongside — not instead of — fingerstick testing. Not a recognized Medicare category.
To qualify: You must have diabetes, be on insulin or prone to hypoglycemia, and your doctor must certify the need. The CGM must be from a participating supplier.
S Diabetic Shoe Benefit — Step by Step
- 1.Your doctor (primary care or podiatrist) certifies that you have diabetes AND at least one of the following: peripheral neuropathy, previous foot ulcer, callus formation, foot deformity, or previous amputation.
- 2.The doctor completes a Certifying Physician Statement (CMS-10055).
- 3.You visit a qualified fitter: a podiatrist, orthotist, prosthetist, pedorthist, or certain physicians.
- 4.The fitter measures and fits the shoes, then bills Medicare directly.
- 5.Medicare covers 80% of the approved amount. You pay 20% (or $0 if you have Medicaid or a good Medigap plan).
Benefit resets each calendar year on January 1.
A Medicare Advantage Plans
⚠️ If your loved one has a Medicare Advantage plan (like Humana, UHC, or Aetna), the rules may differ from Original Medicare:
- →You must use in-network DME suppliers — out-of-network may not be covered.
- →CGMs and insulin pumps may require prior authorization before you can get them.
- →Some MA plans offer enhanced benefits for diabetes — better CGM coverage, $0 insulin, etc.
- →Call the number on the back of the card before ordering. Ask: "Is this CGM covered?" and "Do I need prior authorization?"
Setting Up Effective Home Monitoring
Getting the right equipment is only half the battle — knowing how to use it, when to check, and what the numbers mean is what keeps you safe.
📡 Setting Up and Using a CGM
Inserting the sensor: Most CGMs use a small auto-inserter. Clean the site with an alcohol swab, press the device against your skin, click the button. The sensor stays in place for 10–15 days.
Connecting to your phone or receiver: Most CGMs use Bluetooth. Download the companion app, follow the pairing instructions. Readings appear on your phone automatically.
Setting alerts: Configure high and low glucose alarms. A low alert at 70–80 mg/dL and a high alert at 180–200 mg/dL is a common starting point — adjust with your care team.
Reading the arrows: The CGM shows your current glucose AND a trend arrow. A single down arrow means glucose is falling slowly; two down arrows means falling fast. Act on trend arrows — don't wait for alarms.
🩸 When to Check Manually with a Meter
Even with a CGM, there are times when a fingerstick glucose test is still the right call:
- →When CGM readings don't match how you feel (CGM may lag behind blood glucose by 10–15 minutes)
- →Before and after exercise, when glucose shifts rapidly
- →If you're about to drive or make an important decision based on glucose levels
- →When treating a low blood sugar episode — confirm recovery with a meter
- →If your CGM sensor is ending its wear period or malfunctioning
📱 Apps and Sharing Data with Your Doctor
Modern CGM systems generate a powerful report called the Ambulatory Glucose Profile (AGP) — a standardized one-page summary of 14+ days of glucose data. Your doctor uses this to adjust medication. Share it before every appointment.
Apps to know:
- • Dexcom Clarity — cloud-based reports for Dexcom users
- • LibreView — Abbott FreeStyle Libre data sharing
- • Sugarmate — connects multiple CGMs, Apple Watch support
- • mySugr — diabetes logbook + bolus calculator
Share with your care team:
- • Most CGM apps have a "share" or "follow" feature for family members
- • Your doctor can see your data through clinic-linked portals
- • Download AGP reports as PDF before appointments
- • Ask your diabetes educator to walk through your data with you
🎯 A1C and Time-in-Range — What to Aim For
A1C is a blood test measuring your average glucose over the past 2–3 months. Your home monitoring should support hitting your A1C goal. Most adults with diabetes aim for under 7% — but your doctor may set a different target based on your age, history, and risk tolerance.
70–180 mg/dL
Target glucose range for most adults with diabetes
>70% TIR
Time-in-range goal — 17+ hours/day in target range
<7% A1C
Common A1C target — discuss your personal goal with your doctor
When to Get Help — Warning Signs
Knowing when to call your doctor versus when to go to the ER could save your life or prevent a hospitalization. Here are the key warning signs for the three most dangerous diabetes complications at home.
🚨 Low Blood Sugar (Hypoglycemia) — Below 70 mg/dL
Symptoms:
- • Shakiness, trembling
- • Sweating, chills, clamminess
- • Fast heartbeat
- • Confusion, difficulty concentrating
- • Irritability, anxiety
- • Pale skin, headache
- • Weakness, fatigue
- • Seizures or loss of consciousness (severe)
What to do:
If conscious and able to swallow:
Eat 15g fast-acting carbs (4 glucose tablets, 4 oz juice, 4 oz regular soda). Wait 15 min. Recheck. Repeat if still below 70. Eat a snack once above 70.
Call 911 immediately if:
Unconscious, having a seizure, unable to swallow, or blood sugar stays low after two treatment attempts.
⚠️ High Blood Sugar (Hyperglycemia) — Above 240 mg/dL
Symptoms:
- • Increased thirst and frequent urination
- • Blurred vision
- • Fatigue, sluggishness
- • Headache
- • Fruity-smelling breath (sign of DKA — emergency)
- • Nausea, vomiting, stomach pain (DKA)
When to act:
240–350 mg/dL — Call your doctor:
Drink water. Check for ketones if you have a ketone meter. Follow your sick-day insulin protocol. Call your care team for guidance on correction doses.
Call 911 or go to ER if:
Blood sugar over 350 mg/dL, moderate/large ketones, vomiting, confusion, fruity breath, or rapid breathing. These are signs of DKA (diabetic ketoacidosis) — life-threatening.
🦶 Diabetic Foot Red Flags — Act Quickly
Foot problems in people with diabetes can escalate rapidly because of reduced sensation (neuropathy) and poor circulation. Check your feet every day — including between the toes.
Go to ER or call 911:
Wound that smells foul or has dark/black tissue. Foot that is hot, swollen, and red — especially with fever. Signs of bone infection. Rapid spread of redness up the leg.
Call your doctor same day:
Any new sore, blister, or wound on your foot. Redness, warmth, or swelling in one area. A cut that's not healing after a few days. Ingrown toenail that's becoming infected.
Mention at your next appointment:
New calluses, dry cracked skin, changes in foot shape, or areas of numbness. Ask your podiatrist about custom orthotics if you have callus formation.
📌 Post these numbers somewhere visible: Your diabetes care team's direct line, your endocrinologist or PCP, and 911. For CGM users — silence low glucose alarms during the day is never the right answer. If an alarm is going off frequently, that's a conversation to have with your doctor, not a reason to turn off the alert.
