The correct spelling is Medicare, one word with a capital M
Medicare is spelled M-E-D-I-C-A-R-E. It is one word, not two, and the M is always capitalized because it is the official name of the federal health insurance program. You will see it written this way on government documents, insurance cards, and official websites.
The word comes from "medical care" but is written as a single term. Common misspellings include "Medicaid" (a different program entirely), "Medicare.gov" (which adds the website extension), and "medicaid" or "medicare" in lowercase (which is incorrect in formal writing, though search engines will still find what you mean).
When you are filling out forms, writing to Medicare, or searching for information, use the correct spelling. Government agencies and insurance companies match what you type to their records, so spelling matters when you are looking up your account or submitting documents.
Key Takeaways
- Medicare is spelled as one word with a capital M: M-E-D-I-C-A-R-E.
- Medicaid is a completely different program and is spelled differently — do not confuse the two.
- Correct spelling matters when you search for information, log into your account, or contact Medicare directly.
- Your Medicare card will always display the word spelled correctly, so you can use it as a reference.
Why Medicare is spelled as one word, not two
Medicare became a federal program in 1965 as part of the Social Security Act. The government created the name as a single word to distinguish it from other health programs and to make it a recognizable brand for the program itself. It is similar to how "Medicaid" is also one word — they are both official program names, not descriptions of what they do.
The one-word format is used consistently across all official materials: your insurance card, the Medicare.gov website, letters from Medicare, and enrollment forms. If you see it spelled differently, it is likely a typo or a third-party website that is not directly from the government.
Medicare versus Medicaid: the spelling difference matters
Medicare and Medicaid are two separate programs that are often confused because their names are similar. Medicare is a federal health insurance program for people 65 and older, regardless of income. Medicaid is a joint federal and state program for people with lower incomes, and it is available at any age.
The spelling difference is important because when you search for information or contact an agency, using the wrong name will send you to the wrong program. If you are looking for Medicare information and type "Medicaid," you will get results about a completely different program with different rules, coverage, and enrollment processes.
Check your insurance card or the letter you received when you turned 65 to confirm which program you are in. The name will be spelled correctly on official documents.
Where you will see Medicare spelled correctly
The official Medicare website is Medicare.gov. This is the primary source for accurate information about the program, and you can log into your account there to view your coverage, claims, and personal information. The website spells the program name correctly throughout.
Your Medicare card will display "MEDICARE" across the top. Your name, Medicare number, and coverage details appear below. Insurance companies that offer Medicare plans also use the correct spelling on their websites, bills, and customer service materials.
When you receive mail from Medicare or from your insurance company, the program name will be spelled correctly. If you receive a letter that spells it differently, it may be a scam or a third-party vendor trying to sell you something. Always verify by going directly to Medicare.gov or calling Medicare at 1-800-MEDICARE (1-800-633-4227).
How to search for Medicare information online
When you search for Medicare information, type the word exactly as it is spelled: Medicare. Most search engines will correct minor typos, but using the correct spelling from the start will give you faster results from official sources.
If you are looking for a specific topic — such as prescription drug coverage, enrollment important date, or how to file a claim — type "Medicare" followed by what you need. For example: "Medicare prescription drug coverage" or "Medicare enrollment important date." This will take you to Medicare.gov and other official resources.
Avoid clicking on links from websites you do not recognize, even if they appear high in search results. Scammers sometimes create websites with names similar to Medicare to trick people into giving personal information. Always look for the official Medicare.gov domain in the web address.
Common spelling mistakes and how to avoid them
The most common mistake is spelling it as two words: "Medi care" or "Medi-care." This is incorrect. It is always one word: Medicare. Another frequent error is capitalizing it in the middle of a sentence as "MediCare" — only the M should be capitalized.
Some people also confuse it with Medicaid by adding a "d" at the end. Remember: Medicare is for people 65 and older. Medicaid is for people with lower incomes. The spelling difference helps you keep them straight.
If you are unsure, look at your insurance card or an official letter from Medicare. Copy the spelling exactly as it appears there. You can also visit Medicare.gov and see how the program spells its own name throughout the website.
Frequently Asked Questions
Is it Medicare or Medicaid?
They are two different programs. Medicare is for people 65 and older. Medicaid is for people with lower incomes at any age. The spelling difference reflects the different programs — Medicare (no "d") versus Medicaid (with a "d").
Does it matter how I spell Medicare when I search online?
Most search engines will correct minor spelling mistakes, but using the correct spelling — Medicare, one word, capital M — will give you faster and more accurate results from official sources like Medicare.gov.
What if I see Medicare spelled differently on a website?
If a website spells it differently, it may not be an official source. Check the web address to see if it is Medicare.gov. If you are unsure, call Medicare directly at 1-800-MEDICARE (1-800-633-4227) to verify.
Can I use lowercase "medicare" when I search?
Search engines will understand what you mean, but official documents and formal writing always use a capital M. When you fill out forms or contact Medicare directly, use the correct capitalization: Medicare.
