About  9th Street Internal Medicine in Philadelphia

Ninth Street Internal Medicine (NSIM) is an NCQA recognized Level Three Patient Centered Medical Home (PCMH).

We manage the health and wellness of patients ranging from age 18 through the senior years. We often see two or three generations of a family in our practice.

We emphasize preventive medicine, including age and gender specific cancer screening, immunizations, and evaluation of risk factors for future medical problems.

We use an electronic health record to assure that you receive the best possible care. You can view your medical records and email us securely about prescription refills, referrals, appointment issues, and NON-URGENT medical questions.

We practice medicine as a partnership between us and our patients. We encourage your active participation in your care. We always inform you about your test results and make recommendations to help you achieve the best possible health.

We coordinate the care you receive from specialists, inpatient hospitals and emergency rooms. Your care will no longer be fragmented between providers who do not communicate with each other. Our on-site care managers help update your medical records and arrange needed services after hospitalization so that you have the help you need to recover.

We believe quality matters. We strive to continually improve what we do and assure that all patients get the care they need according to the best scientific evidence available.

We believe in access to care when you need it the most. We can see you for a same day and next day urgent care appointment. These are available with shorter wait time and lower costs than the emergency room.

MDVIP Affiliation

Dr Lillian Cohn, Dr Kenneth Barmach and Dr David Verbofsky are our MDVIP affiliated physicians. They are affiliated with a national program of concierge physicians who focus on personalized wellness and prevention as well as management of chronic and acute disease – this program allows patients to pay an annual membership fee to be part of a smaller patient panel. Those patients also receive all the benefits of being part of the NSIM practice with the same credentials, partnerships and electronic records described above in the NSIM information section of this site.

COVID-19 Update

As your primary care providers, we at Ninth Street Internal Medicine and MDVIP would like to encourage everyone to receive the COVID-19 vaccine when it becomes available to them. We believe in both the safety and efficacy of this vaccine. If you would like to learn more about how mRNA vaccines work, we encourage you to visit https://www.cdc.gov/coronavirus/2019-ncov/vaccines/different-vaccines/mrna.html to learn more. Anyone who still has questions or reservations about getting the vaccine should schedule a phone appointment to discuss with your doctor. This vaccine is the best way for all of us to end this pandemic and get back to normal life!

We encourage everyone who is interested in receiving the vaccine to register with their local health department.

The vaccine is being offered in phases in an effort to get as many high-risk individuals vaccinated as quickly as possible. Please be patient as we go through these phases and understand there will be some variability based on your county of residence, and some of these phases will overlap. Currently we are in Phase 1a (healthcare workers and residents of long-term care facilities). Some areas are now starting Phase 1b (frontline essential workers, people over age 65, and younger adults with chronic medical conditions such as diabetes, cancer, kidney disease, heart disease, COPD, and others). There will be continued updates as vaccine is offered to additional groups, and checking your local health department website is the best way to know when it will be your turn.

We have applied through the Philadelphia Health Department to be a vaccine distributor, but we have not received any vaccine yet. We will send updates via email and the NSIM website if we are approved to distribute vaccine in the future. If you are offered the vaccine through your employer or pharmacy or local health department, you should get the vaccine that way. We will do our best to keep everyone updated as more information becomes available.
