Dr. Kenneth M. Greene in Baltimore: Internal Medicine at Mercy Medical Center
Dr. Kenneth M. Greene is an internist at Mercy Medical Center, the Johns Hopkins-affiliated teaching hospital in West Baltimore. He provides adult primary care, acute illness management, and chronic disease follow-up within the inpatient and outpatient framework of a major academic medical center, placing him among Baltimore's internal medicine physicians who practice within a hospital system rather than a standalone office.
What Dr. Greene actually provides
As an internist in a hospital-based practice, Dr. Greene diagnoses and manages conditions including hypertension, diabetes, heart disease, respiratory illness, infection, and metabolic disorders in adult patients. He carries the medical knowledge and board certification that the specialty requires, but his work is embedded in Mercy's institutional setting, meaning patients access him through hospital scheduling, billing, and care coordination systems rather than an independent practice office. This arrangement places him in a different operational category than solo or small-group internal medicine practices elsewhere in the city.
Access and new-patient status
Mercy Medical Center accepts most major insurance plans, including Medicare, Medicaid, and commercial networks. New-patient appointments must be requested through Mercy's central scheduling system, typically by calling the main hospital line or using the Johns Hopkins patient portal if you are an established Johns Hopkins patient. Lead times for non-urgent appointments average two to four weeks depending on availability and physician demand. The hospital does not maintain a walk-in clinic for internal medicine; all visits are appointment-based. Patients without established coverage should verify insurance eligibility before scheduling.
How he fits within Baltimore's internal medicine landscape
Baltimore's internal medicine options split roughly into three tiers: private practices (often solo or small groups with their own offices), community health centers (Federally Qualified Health Centers like Chase Brexton and Harbor Health that serve uninsured and underinsured populations on a sliding-fee scale), and hospital-based physicians like Dr. Greene. Hospital-based internists offer direct access to hospital resources, specialists, and electronic records, but typically involve longer wait times for routine visits and navigation of institutional bureaucracy. Private practitioners such as those in Canton or Federal Hill may offer same-day sick appointments and shorter waits. Community health centers are the low-cost entry point for uninsured or Medicaid-eligible patients. Dr. Greene's setting suits established patients with insurance who benefit from academic medical continuity and specialist access within Johns Hopkins.
Insurance and costs
Mercy Medical Center operates under Johns Hopkins Health System fee schedules. Office visit copays depend on your specific plan; typical copays for internal medicine visits range from $20 to $50 for in-network patients. Deductibles and coinsurance apply per your policy. Uninsured patients should contact Mercy's financial assistance office before the visit to explore payment plans or income-based discounts; the hospital has an established uninsured discount program. Medicaid and Medicare patients are accepted and billed according to state and federal rates.
First visit and typical appointment flow
New patients should arrive 15 minutes early with photo ID, insurance card, and a list of current medications and any significant medical history. The appointment begins with nursing intake, followed by time with Dr. Greene for history, physical examination, and assessment. If lab work is needed, results are typically available within one to three business days through the hospital system. Follow-up appointment scheduling happens at the end of the visit. Prescription renewals and routine questions can often be handled by phone or through the patient portal if you are established with Johns Hopkins.
Location, parking, and logistics
Mercy Medical Center is located at 301 St. Paul Place in downtown West Baltimore, directly adjacent to Baltimore's medical district and the University of Maryland Medical Center. Parking is available in the adjacent Mercy Medical Center garage (parking fees apply; verify current rates with the hospital). The site is accessible by MTA bus lines 3, 10, and 64. Street parking is limited and metered. For disability or medical mobility concerns, valet parking and accessible parking spaces are available at the main entrance. The hospital operates standard business hours for outpatient scheduling, typically Monday through Friday 8 a.m. to 5 p.m., with limited weekend clinic hours; confirm specific scheduling by calling ahead.
Dr. Greene's position within Johns Hopkins' teaching mission and Mercy's comprehensive care system reflects Baltimore's hospital-centered medical structure and makes him a practical choice for patients seeking internal medicine within an integrated academic system.
