Mark A. Mashburn, MD in Baltimore: Otolaryngology for Adults and Referral Patients
Mark A. Mashburn is an otolaryngologist (ear, nose, and throat specialist) in Baltimore who sees adults for medical and surgical conditions, primarily through referral from primary care physicians or other specialists rather than direct self-referral. His practice focuses on the full range of ENT problems: hearing loss and balance disorders, nasal obstruction and sinus disease, throat complaints, and benign tumors of the head and neck.
What Mashburn Actually Is
Mashburn is a board-certified otolaryngologist operating as a specialist practice in Baltimore. Unlike walk-in urgent care clinics or primary care offices that handle minor ear and throat symptoms, he addresses complex or persistent problems that benefit from the diagnostic tools and surgical expertise an ENT specialist provides. His practice accepts both new patients and established ones, though new-patient appointments typically require a physician referral rather than self-scheduling. He does not operate a clinic open to the public without referral.
Services and Typical Procedures
Mashburn handles diagnostic and treatment services standard to otolaryngology:
- Hearing evaluation and hearing aid consultation
- Balance testing and vertigo management
- Nasal obstruction and deviated septum assessment, including septoplasty
- Chronic sinusitis workup and endoscopic sinus surgery
- Thyroid and laryngeal nodule evaluation
- Benign head and neck tumors
- Voice and swallowing disorders
Pricing is variable and depends on the specific procedure, whether surgery is performed (which involves facility fees), and your insurance coverage. A consultation visit for diagnosis typically runs $150 to $300 out-of-pocket depending on your deductible; surgical procedures are priced individually and include facility and anesthesia charges, which are significant. Insurance authorization and pre-certification are required for most procedures. Call his office to discuss expected costs before scheduling.
How Mashburn Compares to Other Baltimore ENT Options
Baltimore has multiple otolaryngologists in private practice and affiliated with Johns Hopkins, University of Maryland Medical Center, and Sinai Hospital. The key difference is referral requirement versus open access. Many private practices in the city, including larger group practices, accept self-referrals for initial appointments; Mashburn's practice typically requires a physician referral. This is not a barrier if you already have a primary care doctor, but it means you cannot walk in or call and immediately book. Conversely, practices that accept self-referral often have longer wait times for new-patient slots, sometimes 4 to 6 weeks.
Mashburn's practice size and structure favor focused, continuity-of-care relationships rather than high-volume throughput. For straightforward sinus problems or hearing aid fitting, a large group practice or hospital-affiliated clinic may offer quicker availability and more appointment slots. For complex diagnostic work or cases requiring his specific expertise, a smaller specialist practice often allows more unhurried evaluation.
Who Suits This Practice, and Who Does Not
Mashburn suits patients who:
- Have a referral from their primary care physician or another specialist
- Have persistent or complex ENT symptoms that have not resolved with primary care
- Need surgical consultation or evaluation for a head and neck condition
- Prefer continuity with one provider over rapid scheduling
- Have insurance coverage and are willing to manage the authorization and billing process
Mashburn is not a fit for:
- Patients seeking same-day or walk-in acute care for ear infection, sore throat, or earwax impaction (urgent care or your primary doctor is more appropriate)
- Patients without a referral who want to self-refer directly
- Those seeking a large clinic with evening or weekend hours
What the First Visit Involves
Typically, your primary care doctor or specialist submits a referral with a brief clinical history. Mashburn's office calls to schedule, usually offering appointments 1 to 3 weeks out. At your visit, expect a focused history and physical exam. Depending on your problem, he may perform office-based diagnostic testing: audiometry for hearing concerns, balance testing for dizziness, or nasal endoscopy for sinus or nasal complaints. The visit results in a diagnosis and a treatment plan, which may be medical (medications, hearing aids), watchful waiting, or a recommendation for surgery. If surgery is recommended, a separate pre-operative consultation and facility scheduling follow.
Hours, Location, and Logistics
Mashburn practices in Baltimore during standard business hours (typically Monday through Friday, 8 a.m. to 5 p.m., with variation). Confirm current hours by calling his office before scheduling. Parking depends on his office location; most private practices in Baltimore neighborhoods offer street parking or small lots. If affiliated with a hospital system, hospital parking applies. Contact the office for specific address and parking details.
Why Mashburn Merits a Spot in This Guide
Mashburn represents the category of specialist practice that many Baltimore patients need but underutilize: focused, referral-based care that provides unrushed diagnostic expertise for problems that do not belong in urgent care or primary care. His practice exemplifies how otolaryngology works in Baltimore outside the hospital system.
