Is Health Care One Word or Two? Healthcare vs. Health Care Explained

Both health care and healthcare are accepted spellings, but the preferred form depends on the dictionary, publication, and style guide you follow.

Health care is the traditional two-word spelling and remains common in medical, academic, and institutional writing.

Healthcare is an increasingly common one-word spelling. Cambridge lists it as a standard word, and the Associated Press adopted healthcare as one word in 2026.

Examples:

• Access to affordable health care is important.
• She works in the healthcare industry.
• The hospital provides several health care services.

The safest rule is to choose the form required by your style guide and use it consistently.

Quick Answer

Use either:

• health care
• healthcare

Both refer to services intended to maintain, improve, or restore people’s physical or mental health.

However:

• Health care remains the main form listed by Merriam-Webster.
• Healthcare is accepted by Cambridge and is now preferred by AP style.
• Health-care may occasionally be hyphenated before another noun, but the hyphen is often unnecessary.

For general writing, either health care or healthcare can be correct. Consistency matters more than switching between them.

What Does Health Care Mean?

Health care refers to services, treatments, and professional efforts intended to maintain, restore, or improve a person’s health.

Merriam-Webster defines it as efforts made to support someone’s physical, mental, or emotional well-being, especially when those efforts are provided by trained professionals.

Health care may include:

• medical examinations
• hospital treatment
• mental health services
• preventive care
• emergency treatment
• prescription medicine
• rehabilitation
• nursing care

Examples:

• Everyone should have access to reliable health care.
• The country is reforming its health care system.
• Preventive health care can identify problems early.
• She has worked in health care for ten years.

Is Health Care Two Words?

Yes. Health care as two words is a standard and widely accepted spelling.

Merriam-Webster enters the term as health care, and the American Medical Association regularly uses the two-word form in phrases such as health care professionals and health care definitions.

Examples:

• health care system
• health care provider
• health care costs
• health care services
• health care policy

This spelling is especially common in medical organizations, academic writing, policy discussions, and publications that follow a traditional house style.

Is Healthcare One Word?

Yes. Healthcare is also a standard word.

Cambridge lists healthcare as a noun referring to the activity or business of providing medical services. The one-word spelling is common in British English, corporate writing, job titles, and modern news or business content.

Examples:

• She works in healthcare.
• The company develops healthcare technology.
• Rising healthcare costs concern many families.
• He is a healthcare consultant.

The one-word form has become increasingly familiar because the two elements are often treated as one established concept.

Health Care vs. Healthcare

The two spellings usually have the same meaning.

Form	Status	Common Use
Health care	Standard traditional form	Medical, academic, and institutional writing
Healthcare	Standard modern form	AP style, British English, business, and general writing
Health-care	Possible hyphenated form	Occasionally used before another noun

Compare:

• The government is reviewing health care costs.
• The government is reviewing healthcare costs.

Both sentences are understandable and grammatically acceptable.

The main difference is editorial style rather than meaning.

Why Do Dictionaries Disagree?

Compound terms often change spelling over time.

A phrase may begin as two words, later appear with a hyphen, and eventually become one word.

Examples of this process include:

• web site → website
• data base → database
• on line → online

Health care is currently used in more than one accepted form. Merriam-Webster favors the open form, while Cambridge recognizes the closed form healthcare.

This does not mean that one dictionary is wrong. Dictionaries may record different regional traditions, editorial preferences, and patterns of usage.

What Does AP Style Recommend?

The Associated Press previously preferred health care as two words.

In 2026, AP changed its guidance and adopted healthcare as one word. The change reflected the increasing frequency and acceptance of the closed spelling.

Therefore, writers following current AP style should use:

healthcare

Examples:

• healthcare costs
• healthcare workers
• the healthcare industry
• healthcare reform

This change is especially relevant to journalists, news websites, and publications that follow the AP Stylebook.

What Does Medical Style Prefer?

Medical organizations may continue to use health care as two words.

The American Medical Association uses phrases such as:

• health care professional
• health care organization
• health care definitions

This makes health care a sensible choice for writers following AMA conventions or matching the terminology used by a particular medical publication.

Always check the publication’s own guidelines before changing its preferred spelling.

Is Health-Care Hyphenated?

Merriam-Webster notes that health care is sometimes hyphenated when it appears before another noun.

Examples include:

• health-care provider
• health-care system
• health-care costs

However, many current styles use either:

• health care provider
• healthcare provider

The hyphenated form is therefore possible but less necessary than it once was.

Do not write:

• health-care, when the term stands alone

Less natural:

• Access to health-care is important.

Better:

• Access to health care is important.
• Access to healthcare is important.

Health Care as a Noun

Use health care as a noun when naming the service or field.

Examples:

• She works in health care.
• The community needs better health care.
• They cannot afford private health care.
• Access to health care varies by region.

The one-word form can be used in the same position:

• She works in healthcare.
• The community needs better healthcare.

Health Care Before Another Noun

The term often modifies another noun.

Examples:

• health care worker
• health care system
• health care plan
• health care facility
• health care policy

With the one-word style, write:

• healthcare worker
• healthcare system
• healthcare plan
• healthcare facility
• healthcare policy

Both patterns are common.

Avoid mixing them within the same document unless you are preserving an official name.

Inconsistent:

• The healthcare system employs many health care workers.

Consistent:

• The healthcare system employs many healthcare workers.
• The health care system employs many health care workers.

Is It Healthcare Provider or Health Care Provider?

Both are correct.

Use healthcare provider when following the one-word style:

• Contact your healthcare provider.

Use health care provider when following the traditional two-word style:

• Contact your health care provider.

The phrase may refer broadly to a person or organization that provides medical services. In precise medical writing, naming the specific professional may be clearer:

• doctor
• nurse
• pharmacist
• hospital
• physical therapist

The AMA notes that the general word provider can be unclear when a more specific term is available.

Is It Healthcare Worker or Health Care Worker?

Both forms are accepted.

Examples:

• She is a healthcare worker.
• She is a health care worker.

Use the spelling preferred by your employer, publication, or style guide.

If the organization officially uses a title such as Health Care Workers Association, preserve that spelling even if the rest of your document uses healthcare.

Is It Healthcare System or Health Care System?

Both are correct:

• healthcare system
• health care system

Examples:

• The country has a public healthcare system.
• The country has a public health care system.

The meaning does not change.

Writers following current AP style will generally choose healthcare system, while organizations following Merriam-Webster or AMA-style conventions may choose health care system.

Common Mistakes

Assuming only one spelling can ever be correct

Both health care and healthcare are accepted.

The preferred form depends on style.

Switching spellings unnecessarily

Inconsistent:

• Healthcare costs affect the entire health care industry.

Consistent:

• Healthcare costs affect the entire healthcare industry.
• Health care costs affect the entire health care industry.

Adding an unnecessary hyphen

Less common:

• health-care services

Usually simpler:

• health care services
• healthcare services

Ignoring an official name

Always preserve the spelling used in the official name of a company, department, organization, or publication.

How to Remember the Difference

Think of the two forms as style choices rather than different meanings.

• Health care emphasizes care related to health.
• Healthcare treats the entire field as one established concept.

A useful memory rule is:

Both forms can be correct—choose one style and keep it consistent.

Final Answer

Health care can be written as two words, and healthcare can be written as one word.

Health care is the traditional spelling and remains common in medical and institutional writing.

Healthcare is a widely accepted modern spelling and became the preferred AP style in 2026.

Correct:

• health care services
• healthcare services
• health care workers
• healthcare workers

The meaning is the same.

Remember:

Health care and healthcare are both correct—follow your style guide and stay consistent.
