How New Castle compares with the U.S.
768 active clinicians list a practice address in New Castle, DE in the NPI registry.
New Castle has fewer than 10,000 residents, so rates per 100,000 people change a lot with each clinician and are not compared here.
98% of clinicians in New Castle listed in the CMS Medicare file (192 of 196) accept Medicare assignment. That is similar to the Delaware share of 94%.
Only 196 of 768 active clinicians in New Castle 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.
18% of clinicians in New Castle listed in the CMS Medicare file (36 of 196) have a CMS telehealth indicator, meaning their recent Medicare claims include telehealth services. That is lower than the Delaware share of 25%.
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 Registry addresses can be out of date.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.
