How Maryland compares with the U.S.

Compared with the U.S. as a whole, Maryland has more clinicians in Home Health Aide (7.6x), clinicians in Rehabilitation Counselor - Orientation and Mobility Training Provider (7.0x) and clinicians in Military Health Care Provider (6.4x) per 100,000 residents.

It has fewer Rehabilitation Practitioners (6% of the U.S. rate), Developmental Therapists (7%) and Peer Specialists (9%) per 100,000 residents.

Maryland has 2,598 active clinicians per 100,000 residents, compared with 2,198 for the U.S.

What these numbers mean

Clinicians per 100,000 residents compares places of different sizes. We count active clinicians who list a practice address in the area in the federal NPI registry (NPPES) and divide by the number of people who live there, according to the U.S. Census Bureau. The U.S. rate is the same calculation for the whole country.

A higher number does not mean it is easier to get an appointment, that wait times are shorter, or that care is better. It also does not show how many clinicians are accepting new patients or which insurance plans they take. A lower number does not by itself mean there is a shortage.

84% of clinicians in Maryland listed in the CMS Medicare file (27,602 of 32,891) accept Medicare assignment. That is lower than the U.S. share of 92%.

Only 32,891 of 161,202 active clinicians in Maryland appear in the CMS Medicare file, so this share describes that smaller group.

What is Medicare assignment?

A clinician who accepts Medicare assignment agrees to take the Medicare-approved amount as full payment for services that Original Medicare covers. You usually still pay your deductible and coinsurance. This comes from the CMS Doctors and Clinicians file and applies to Original Medicare only. Medicare Advantage plans have their own provider networks. It does not show whether a clinician is taking new patients.

Some clinicians are listed as "may accept assignment," which means they can decide case by case. Clinicians without an assignment flag, or who are not in the CMS file, are not counted as accepting assignment. That does not mean they refuse Medicare. Ask the office before your visit.

27% of clinicians in Maryland listed in the CMS Medicare file (8,832 of 32,891) have a CMS telehealth indicator, meaning their recent Medicare claims include telehealth services. That is higher than the U.S. share of 21%.

About the telehealth indicator

The telehealth indicator comes from CMS. It marks clinicians whose recent paid Medicare claims include services delivered by telehealth. It means a clinician has provided some services by telehealth, not that every visit can be done online. A clinician without the indicator may still offer telehealth, for example to patients who are not on Medicare. Ask the office which visits can be done by video or phone.

These figures summarize public federal data. They do not measure quality of care, appointment availability, or whether a clinician accepts your insurance or new patients. Registry addresses can be out of date. Please confirm details directly with the office and your plan. This information is not medical advice.
