Katherine S. Maul MD, FCCP in Baltimore: Pulmonology in Canton

Katherine S. Maul MD, FCCP is a pulmonologist in Baltimore's Canton neighborhood who diagnoses and treats chronic respiratory diseases, sleep disorders, and lung conditions ranging from asthma and COPD to interstitial lung disease and occupational lung exposures. She holds board certification through the American Board of Internal Medicine in pulmonary disease and critical care medicine, credentials that require ongoing continuing medical education beyond the initial MD and fellowship training.

What this practice actually is

Maul operates as an independent pulmonology specialist, not as part of a hospital-based clinic or large health system. This setup means referrals from primary care physicians typically flow directly to her practice rather than through a hospital network. She accepts patients with established diagnoses who need ongoing management, acute respiratory symptoms, second opinions, and sleep study interpretation. The practice is small and focused, without the infrastructure of a hospital pulmonology department but also without the scheduling delays that sometimes accompany those larger settings.

Services and what to expect

A typical first appointment with Maul includes a detailed history focused on breathing symptoms, occupational or environmental exposures, smoking history, and medication review. Pulmonary function testing (spirometry) may occur on the first visit or be scheduled after, to measure lung capacity and airflow. For suspected sleep apnea, she orders home sleep studies or in-lab polysomnography. She interprets these tests and adjusts diagnoses and medications based on results.

Common conditions managed in her practice include COPD (which is treated with inhalers, pulmonary rehabilitation referrals, and exacerbation prevention), asthma (controller and rescue inhalers, potential biologic therapies), interstitial lung diseases (which may require chest imaging and sometimes lung biopsy coordination), and occupational lung disease (silicosis, asbestosis, hypersensitivity pneumonitis). Sleep apnea treatment involves either CPAP (continuous positive airway pressure) therapy initiation or referral to sleep medicine if complex sleep disorders are suspected.

Pricing and insurance information is not published online. Maul accepts Medicare and most commercial insurance plans; confirm coverage before scheduling. Out-of-pocket costs depend on your plan's deductible and coinsurance. Pulmonary function testing typically costs between 200 and 400 dollars at the time of service if uninsured, but this varies by facility and should be verified directly.

How this practice compares locally

Baltimore has pulmonology coverage through Johns Hopkins Medicine (including Johns Hopkins Bayview Medical Center), University of Maryland Medical Center, Mercy Medical Center, and independent specialists like Maul. Johns Hopkins pulmonology typically has longer appointment waits (4 to 8 weeks for non-urgent referrals) because of high volume and research commitments, but offers immediate access to inpatient critical care if complex cases require hospitalization. University of Maryland pulmonology offers similar breadth but with variable wait times depending on the specific provider. Independent practices like Maul's usually have shorter wait times (1 to 3 weeks) and a more continuity-focused model where the same doctor sees you across multiple visits, but if you need inpatient pulmonary critical care, coordination with a hospital becomes necessary.

Choose Maul if you have a stable chronic respiratory condition, need a focused specialist with straightforward scheduling, or want consistent one-on-one care. Choose Johns Hopkins if you have a complex case, suspect rare lung disease, or need rapid access to a hospital pulmonary ICU. Choose University of Maryland if you prefer an academic medical center but want more scheduling flexibility than Johns Hopkins typically offers.

Who this practice suits and does not suit

This practice suits adults with diagnosed or suspected chronic pulmonary conditions, occupational lung disease histories, sleep apnea, or medication-resistant asthma. It also suits patients who prefer long-term continuity with one provider. It does not suit patients in acute respiratory distress (who need an emergency department), those requiring pulmonary critical care (ICU-level mechanical ventilation), or those needing lung cancer staging and oncology coordination (which typically happens within a hospital system). Pediatric respiratory conditions are generally managed by pediatric pulmonologists at Johns Hopkins or University of Maryland Children's Hospital rather than adult specialists.

What the first visit involves

Bring your primary care referral, a list of current medications, and your insurance card. The visit takes 45 to 60 minutes. Maul asks detailed questions about when symptoms started, what triggers them, how they affect your daily activity, past medical history, and occupational history. She performs a physical exam including lung auscultation with a stethoscope. Depending on your presentation, she may order spirometry (breathing tests) on-site or at a nearby lab, chest X-ray imaging, or sleep study equipment. She explains findings in plain language and reviews treatment options before you leave.

Hours, parking, and location logistics

Maul's office is located in Canton, Baltimore's residential neighborhood east of downtown near Fells Point. Street parking is available but sometimes limited during business hours; arrive 10 to 15 minutes early. Verification note: exact hours are not publicly posted; call the practice to confirm current schedule, as pulmonology practices sometimes reduce hours during summer or for continuing medical education. The office is not directly accessible by bus; the nearest MTA light rail stop is a 10-minute walk away.

Katherine Maul's independent practice fills a practical gap for Baltimore patients who need expert pulmonology without hospital system wait times and prefer continuity of care over rotating providers.
