Andrew Catanzaro, MD in Baltimore: Infectious Disease Care with Adult and Pediatric Expertise
Andrew Catanzaro, MD, is an infectious disease specialist serving adult and pediatric patients at an office-based practice in Baltimore, with referral-based and established-patient care for conditions ranging from respiratory and bloodstream infections to post-travel illnesses and immunocompromised patient management.
What This Practice Actually Is
Infectious disease physicians diagnose and treat infections caused by bacteria, viruses, fungi, and parasites, and they manage immunocompromised patients and complex cases that primary-care doctors refer. Catanzaro's practice combines general infectious disease coverage with a noted capacity for pediatric infectious disease, a less common focus in Baltimore that expands the number of local families able to stay within the city for specialized care rather than traveling to pediatric-only centers.
Scope of Services and Referral Requirements
The practice handles acute infections (pneumonia, sepsis, cellulitis, urinary tract infections), chronic or recurrent infections, post-hospitalization complications, travel-related illnesses (malaria evaluation, dengue, traveler's diarrhea assessment), and immunocompromised patient care including those with HIV, cancer-related immunosuppression, or transplant-related needs. Both adult and pediatric patients are seen; however, many pediatric infectious disease cases are managed by pediatric specialists at Johns Hopkins Children's Center and University of Maryland Medical Center's pediatric services, making an office practice with pediatric capacity relatively less common in Baltimore.
A referral is typically required to establish care, usually from a primary-care physician, hospitalist, or emergency department provider. Existing patients can often schedule follow-ups directly.
Comparison to Baltimore Infectious Disease Options
Baltimore's infectious disease workforce is concentrated at academic medical centers. Johns Hopkins Bayview Medical Center, Johns Hopkins Hospital, and University of Maryland Medical Center all house infectious disease divisions that take referrals and manage inpatient and outpatient care, but appointments at these centers often have longer wait times (4-8 weeks for routine cases) and are embedded in large hospital systems where scheduling reflects institutional capacity. University of Maryland's infectious disease clinic typically handles 2-4 week lead times for non-urgent referrals.
Catanzaro's private-practice model allows for more direct scheduling of established patients and sometimes faster access for acute issues within the office structure, though wait times for new consultations should be confirmed. For pediatric infectious disease specifically, the academic centers remain primary referral destinations for families seeking sub-specialist care, but Catanzaro's cross-generational practice reduces the need for some families to coordinate care between adult and child specialists.
Insurance and Payment
The practice accepts major commercial insurance plans; patients should verify coverage and out-of-pocket costs with their insurance carrier before the first visit. The specific fee-for-service costs are not publicly disclosed; copays and deductibles depend on the patient's plan.
First Visit Expectations
New-patient visits typically include a detailed infection history (symptom timeline, exposures, recent travel, sick contacts), a physical examination, and often laboratory or imaging orders on the same day if infection is suspected. Patients should bring insurance information, a list of current medications, and any recent lab results or culture reports from hospitalizations or urgent care visits. For pediatric patients, vaccination records and relevant birth history (prematurity, congenital conditions) support clinical decision-making.
Hours and Logistics
The practice operates at an office location in Baltimore; specific hours should be verified directly, as scheduling adjusts seasonally and specialists often reserve time for hospital consultations. Parking is typically available at the office; street parking in surrounding neighborhoods should be confirmed if lot space is full.
Why This Practice Matters for Baltimore
Infectious disease expertise at the specialist level in a private office setting reduces referral bottlenecks for uncomplicated outpatient infections and offers families with pediatric patients a local alternative to hospital-based pediatric divisions for straightforward diagnosis and management.
