Low testosterone can affect energy, sexual health, mood, muscle strength, red blood cell levels, and bone health. But symptoms alone are not enough to diagnose it.
For Medicare, the most important point is this: testing and treatment may be covered when they are medically necessary, properly documented, and tied to a covered medical condition. Coverage can depend on the type of test, the treatment setting, the drug, your plan rules, and local Medicare policies.

Common Questions
What Is Low Testosterone?
Low testosterone is often called male hypogonadism or testosterone deficiency. It means the body does not make enough testosterone, sperm, or both.^1
Testosterone plays a role in sex drive, erections, muscle mass, bone density, red blood cell production, mood, and overall male development.^1
What This Means for You
Low testosterone is real, and it can be treatable. But “low T” should not be diagnosed from symptoms alone. Medical guidelines generally look for both symptoms and consistently low testosterone levels before diagnosis.^2
Types of Low Testosterone
Primary hypogonadism starts in the testicles. The testicles do not make enough testosterone even though the brain is sending signals.
Secondary hypogonadism involves the pituitary gland, hypothalamus, or brain signaling system. The testicles may be able to work, but they are not getting the right hormonal signals.
Common Symptoms and Warning Signs
Low testosterone may cause:
Low sex drive
Fewer morning erections
Erectile dysfunction
Fatigue or low energy
Low mood or motivation
Loss of muscle mass
Increased body fat
Low bone density or fractures
Anemia
Infertility
Breast tenderness or enlargement
Watch For
Some symptoms, such as tiredness, low mood, poor sleep, and weight gain, can also come from other conditions. Depression, sleep apnea, thyroid disease, diabetes, medication side effects, obesity, and heart disease can overlap with low testosterone symptoms.
Why Low Testosterone Matters
Low testosterone may affect quality of life, sexual health, strength, bone health, and red blood cell levels. It can also be a clue that something else is going on, such as a testicular condition, pituitary problem, medication effect, chronic illness, or metabolic issue.
Some research suggests true hypogonadism is much less common than general “low T” marketing may imply. One Medicare local coverage policy discusses estimates around 1.5% to 2.5% when low testosterone is defined by both sexual symptoms and a low testosterone level.^3
Causes and Risk Factors
Low testosterone can be linked to:
Testicular injury or infection
Pituitary or hypothalamus problems
Genetic conditions
Chemotherapy or radiation
Obesity
Diabetes or chronic illness
Sleep problems
Opioids, glucocorticoids, or other medications
Aging-related testosterone decline
Normal aging can lower testosterone levels, but aging alone does not automatically mean a person has a disease that Medicare will cover for testosterone treatment. Medicare coverage may depend on whether there is a documented medical cause.
Prevention and Screening
There is no standard Medicare preventive screening benefit just for low testosterone in every man. Testing is usually considered when symptoms, exam findings, or medical history suggest a possible hormone problem.
Healthy sleep, weight management, physical activity, diabetes control, and medication review may help address some factors that contribute to low testosterone or similar symptoms.
Why This Matters
Before starting testosterone therapy, it helps to ask: “Are we treating confirmed testosterone deficiency, or are we trying to explain symptoms that may have another cause?”
Testing is usually considered when symptoms, exam findings, medications, or medical history suggest a possible hormone problem.
How Low Testosterone Is Diagnosed
Diagnosis usually starts with a conversation about symptoms, medical history, medications, and risk factors. Blood testing is important.
The Endocrine Society recommends diagnosing hypogonadism only when symptoms or signs match testosterone deficiency and testosterone levels are clearly and consistently low.^2 It also recommends confirming low testosterone with repeat morning fasting testing.^2
A Medicare local coverage determination for treatment of males with low testosterone expects at least two separate fasting testosterone levels on two different days before 10 a.m., along with luteinizing hormone (LH) and/or follicle-stimulating hormone (FSH) testing to help identify the cause.^3
Other tests may include prolactin, hematocrit, prostate-specific antigen (PSA), thyroid testing, metabolic labs, or pituitary evaluation when clinically needed.
How Medicare May Cover Diagnosis
Medicare Part B covers medically necessary services and supplies used to diagnose or treat a medical condition.^4 This may include doctor visits, specialist visits, outpatient care, and diagnostic testing when ordered for a medical reason.
Medicare also covers many diagnostic laboratory tests, such as blood tests, when they are medically necessary and ordered by a qualified provider. Medicare.gov says you usually pay nothing for covered diagnostic lab tests, but some related services or noncovered tests may bring costs.^5
What This Means for You
Ask the doctor or lab whether the testosterone test and related hormone tests are expected to be covered, whether they are medically necessary, and what diagnosis code is being used.
Treatment Options
Treatment depends on the cause. For confirmed hypogonadism, a doctor may discuss testosterone replacement therapy (TRT).
Testosterone may come as:
Skin gels
Patches
Injections
Pellets
Nasal or buccal products
Certain oral products
Treatment is not right for everyone. Testosterone therapy can reduce sperm production, so men who want fertility should discuss other options with a specialist.^2
Doctors may also treat underlying issues, such as sleep apnea, obesity, diabetes, medication side effects, or pituitary disease.
Coverage may depend on symptoms, two low morning testosterone results, the cause of low testosterone, medical necessity, local Medicare rules, and plan requirements.
How Medicare May Cover Treatment
Medicare coverage for testosterone treatment is not automatic.
Medicare policy, LCD L39086, says testosterone treatment may be medically reasonable and necessary for symptomatic hypogonadism due to disorders of the testicles, pituitary gland, or brain, among other listed indications.^3 The same policy excludes some situations, including aging-related hypogonadism, “male menopause,” and idiopathic low testosterone not tied to a covered disorder.^3
This is a local coverage determination, not a national rule for every Medicare situation. Still, it is a helpful example of how Medicare may evaluate medical necessity.
What to Watch For
Before starting therapy, ask:
Is this diagnosis covered?
Do I have two low morning testosterone results?
Has the cause been evaluated?
Is this treatment billed under Part B or Part D?
Does my plan require prior authorization?
Follow-Up
Low testosterone treatment is not usually a “one visit and done” issue. Follow-up may include symptom review, repeat testosterone testing, hematocrit or hemoglobin testing, prostate monitoring when appropriate, blood pressure checks, and dose adjustments.
Recovery may also include lifestyle changes, strength-building, sleep improvement, or treatment of related conditions.
How Medicare May Cover Recovery and Follow-Up
Follow-up visits, lab monitoring, and specialist care may be covered under Part B when medically necessary. Usual Part B costs may apply unless the service is a covered lab test with no cost sharing.
If physical therapy, nutrition counseling, sleep testing, or other services are needed for related conditions, coverage depends on the service, medical necessity, and Medicare rules.
Medications
Many testosterone products used at home are more likely to fall under Medicare Part D, if the drug is on the plan’s formulary and plan requirements are met.
Part D plans may use prior authorization, step therapy, quantity limits, and other drug rules.^6 A formulary is the plan’s covered drug list.
Some testosterone treatments given in a doctor’s office or outpatient setting may involve Part B billing, depending on the product, setting, and local rules.
How Medicare May Cover Medications
Part D coverage varies by plan. One plan may cover a specific testosterone gel, while another may prefer injections or require prior authorization.
Part B may apply to certain drugs given in a medical setting, but the route and setting matter. Office-administered injections or pellets may be handled differently from prescriptions picked up at a pharmacy.
Before filling a prescription, ask the pharmacy or plan: “Is this covered, what tier is it on, does it need prior authorization, and are there lower-cost covered alternatives?”
What Medicare May Not Fully Cover
Medicare may not cover testosterone therapy for:
Normal aging alone
General vitality or energy
Bodybuilding or athletic performance
“Male menopause”
Borderline testosterone without documented symptoms and cause
Treatment from cash-pay or online clinics that do not bill Medicare
Coverage can also be denied if testing is incomplete, too frequent, not medically necessary, or missing the required documentation.
Medicare Advantage Considerations
Medicare Advantage plans must cover Medicare-covered services, but they can use networks, referrals, prior authorization, preferred labs, drug formularies, and different cost sharing.
A Medicare Advantage plan may also have its own rules for testosterone products. Always check the plan before scheduling treatment, using a lab, or filling a prescription.
Common Questions
Does Medicare Cover Testosterone Blood Tests?
Medicare may cover testosterone blood tests when they are medically necessary, ordered by a provider, and used to diagnose or treat a medical condition.^5
Does Medicare Cover Testosterone Therapy?
It may, but only when coverage rules are met. Documentation often matters, including symptoms, repeat low morning testosterone levels, cause evaluation, and medical necessity.^3
Is Testosterone Covered Under Part B or Part D?
It depends. Pharmacy-filled testosterone products are often Part D. Some office-administered treatments may involve Part B. The setting, drug form, and billing method matter.
Can Medicare Deny Testosterone for Age-Related Low T?
Yes, it may. At least one Medicare local coverage policy excludes aging-related hypogonadism and “male menopause” as covered indications.^3
What to Do Next
If low testosterone is suspected, start with a primary care doctor, urologist, or endocrinologist. Bring a list of symptoms, medications, past test results, and questions.
Ask these before treatment begins:
Do my symptoms fit testosterone deficiency?
Have we checked two morning testosterone levels?
Do we know the likely cause?
Is testosterone safe for me?
How will blood pressure, hematocrit, PSA, and symptoms be monitored?
Will Medicare or my plan cover the tests and treatment?

Key Takeaways
Low testosterone should be diagnosed with both symptoms and consistently low lab results.
Medicare may cover medically necessary testing and follow-up care.
Testosterone therapy coverage depends on diagnosis, documentation, local rules, drug form, and plan requirements.
Part D may cover many at-home testosterone products, but formulary and prior authorization rules may apply.
Always confirm coverage before starting treatment.
Low testosterone can feel confusing, especially when symptoms overlap with many other health issues. The best next step is a careful diagnosis, a clear treatment plan, and a coverage check before costs begin.
