Our Allentown–Lehigh Valley listings cover the Lehigh Valley and the towns around it: Lehigh County, Berks County, Northampton County, Bucks County, Montgomery County, Carbon County, Schuylkill County and Monroe County. That takes in Allentown, Bethlehem and Easton, plus Reading and Wyomissing to the southwest, Lehighton to the north and Sellersville and Quakertown to the south.
Much of the specialist care here comes through two names you'll see over and over: LVPG and St. Luke's. Around Reading, Reading Hospital's Miller Regional Heart Center appears, and Penn has offices in Sellersville and Limerick. Independent groups include Digestive Disease Associates and Respiratory Specialists.
Allentown and Bethlehem have the most listings. Berks County patients can start with Wyomissing, West Reading or Reading. In Carbon County, look in Lehighton and Palmerton. Pottstown and Royersford serve the southern edge of the area. Offices for the same group can be far apart, so check the town before you call.
LVPG Pulmonary and Critical Care Medicine is the largest lung care group in our listings here, centered in Allentown with an office in Palmer Township. Respiratory Specialists appears too, and St. Luke's has pulmonary offices in Bethlehem and Easton. Wyomissing, Fountain Hill and Sellersville are other places to look.

A pulmonologist is a doctor who diagnoses and treats conditions of the lungs and airways. People see one for asthma that's hard to control, COPD, a cough that won't go away, lung nodules found on a scan, pneumonia that keeps coming back, sarcoidosis, pulmonary fibrosis and sleep apnea [2]. Most people see one after a referral from their primary care doctor.
Start with the kind of care you need. Many pulmonologists also work in other areas:
If you're not sure, a general pulmonologist is the right first stop. They'll refer you on if you need a subspecialist.
Check credentials. The American Board of Internal Medicine certifies doctors in pulmonary disease, critical care medicine and sleep medicine. You can look up any doctor's certification for free on the ABIM website [1]. Our listings show the credentials doctors report in the federal NPI registry, but we don't verify board certification.
Ask about testing. Most lung care starts with tests. Ask whether the practice does breathing tests (pulmonary function tests) and sleep studies in the office, or sends you elsewhere. For sleep apnea, ask if they offer home sleep tests.
Know if you qualify for lung cancer screening. Experts recommend a yearly low-dose CT scan for adults ages 50 to 80 who have a 20 pack-year smoking history and still smoke or quit within the past 15 years [3]. Medicare covers this screening once a year for people who qualify [4].
Confirm insurance before you book. Practices change the plans they accept, so call the office or check your insurer's directory. HMO plans usually need a referral first. Medicare Part B covers medically necessary specialist visits; you typically pay 20% of the Medicare-approved amount after your deductible [5].
Know when not to wait. Breathing trouble that comes on suddenly or makes it hard to talk, or someone who stops breathing, needs emergency care, not an appointment [6]. Call 911.
It depends on your insurance. Most HMO plans require a referral from your primary care doctor before they'll cover a specialist visit. PPO plans and traditional Medicare usually don't. Even without a requirement, many lung practices ask for your recent chest X-ray, CT scan or test results, so call ahead and ask what to bring.
Expect questions about your breathing, cough, sleep, smoking history, work and home exposures, and medications, plus a physical exam. Many first visits include breathing tests that measure how well your lungs move air. The doctor may order a chest CT, blood work or a sleep study. Bring your inhalers and any recent scans.
Many do. Sleep medicine is a separate board certification, and many pulmonologists hold it. A sleep doctor can order a sleep study, at home or in a lab, and manage treatment such as a CPAP machine. Ask the practice whether they treat sleep apnea before you book, since not every lung doctor does.
The U.S. Preventive Services Task Force recommends a yearly low-dose CT scan for adults ages 50 to 80 who have smoked at least 20 pack-years and still smoke or quit within the past 15 years. A pack-year is one pack a day for one year. Medicare covers yearly screening for people ages 50 to 77 who qualify.
Look the doctor up on the American Board of Internal Medicine's free "Verify a Physician" tool. It shows whether a doctor is certified in pulmonary disease, critical care medicine or sleep medicine. Our listings show the credentials doctors report to the NPI registry, but we don't verify certification ourselves.
