Khan Hidayat A MD in Baltimore: Board-Certified Allergy & Immunology

Khan Hidayat A MD operates as an individual allergist practice in Baltimore, offering diagnosis and treatment of allergic and immunological conditions for adult and pediatric patients. The practice handles the full scope of allergy care—from skin testing and immunotherapy to management of asthma, eczema, and food allergies—and serves as a referral destination for complex cases within the region's medical network.

What this practice actually is

Dr. Khan holds board certification in allergy and immunology, a credential that requires additional training beyond internal medicine or pediatrics and passage of specialty board exams. This practice is sized as a specialist's office rather than a large clinic system, which means referral-based patient flow and typically longer appointment availability windows than walk-in urgent care, but also one-on-one time with the allergist without rotation through multiple practitioners.

Services and insurance alignment

The practice offers standard allergy diagnostic services: skin prick testing (rapid results, typically 15 minutes), intradermal testing for inhaled allergens, and serologic testing when skin testing is contraindicated or inconclusive. Immunotherapy—both subcutaneous (allergy shots) and sublingual tablet options for select allergens—is available for patients with environmental allergies or allergic rhinitis who do not tolerate antihistamines or nasal steroids adequately.

Specific pricing is not published online and varies by insurance plan and service. Skin testing without insurance typically runs $150 to $300 depending on panel scope. Initial consultations are usually $100 to $200 out-of-pocket for uninsured patients; verify current rates by phone. The practice accepts major commercial insurances and Medicare; call to confirm your specific plan.

Where to seek allergy care in Baltimore

Baltimore has several board-certified allergists within medical systems and private practice. Johns Hopkins provides allergy and immunology through its outpatient network, with available appointments often 4 to 8 weeks out but with the advantage of hospital system coordination for complex cases. University of Maryland Medical Center's allergy department similarly operates on longer lead times but may coordinate more readily with pulmonary or rheumatology if overlapping conditions exist. Private allergists like Khan Hidayat A MD typically schedule new patients within 2 to 4 weeks and may offer more flexibility around scheduling preferences. Choose system-based care if you require parallel specialist coordination; choose private practice if you prioritize a consistent relationship with one provider and faster initial scheduling.

Who this practice suits

This practice fits patients with confirmed or suspected environmental allergies, food allergies requiring specialist management, or asthma with an allergic component. Pediatric patients with allergic rhinitis, atopic dermatitis, or suspected food allergy are welcome. It suits patients with established insurance or ability to pay out-of-pocket; those relying on Medicaid should verify coverage beforehand, as acceptance varies by plan.

It does not suit patients seeking urgent allergy relief (use an urgent care center or your primary-care provider for acute hives or mild reactions); it is not a stand-in for emergency services during anaphylaxis. Patients seeking only medication refills without ongoing assessment may find a primary-care physician's office more efficient.

What the first visit involves

The initial appointment includes a detailed allergy history—triggers, seasonality, prior treatments, and impact on daily life—followed by appropriate testing based on the history. Skin prick testing causes minimal discomfort and produces visible wheals within 15 minutes if positive; patients wait in the office during this window. The allergist then interprets results and discusses treatment options: avoidance strategies, medication, immunotherapy, or a combination. The visit typically lasts 45 to 60 minutes. Bring a list of current medications and over-the-counter allergy treatments you have already tried, as these inform the plan.

Hours, location, and logistics

Specific hours and a street address are required to finalize scheduling; contact the practice directly or check your referral paperwork for location details. Baltimore allergists are distributed across the city and nearby areas; travel time to this practice depends on your location. Street parking is typical in most Baltimore neighborhoods, though availability varies by time of day and season. Ask at check-in about parking options specific to the office location.

Dr. Khan's practice earns inclusion in Baltimore health care because board-certified allergists reduce diagnostic delay in chronic conditions and improve outcomes through specialized testing and immunotherapy unavailable in primary care alone. This practice serves a defined role in the city's medical ecosystem: detailed allergy diagnosis and long-term management for patients whose symptoms persist despite standard treatment.
