Understand Your Medical Bill
Look up the CPT codes on your bill and find out what you were actually charged for — in plain language, with typical costs and common billing errors to watch for.
Office Visits & Consultations
The most common codes on your bill. These cover routine check-ups, follow-up visits, and new patient appointments. Upcoding (billing a higher-level visit than what occurred) is one of the most frequent billing errors.
Preventive Care & Annual Physicals
Preventive visits are often covered at 100% by insurance — but only if coded correctly. If your annual physical gets billed as a regular office visit, you could owe a copay you shouldn't.
Emergency Room & Hospital Visits
ER bills are notoriously confusing and expensive. Understanding the severity levels helps you spot when a visit was coded higher than it should have been.
Lab Work & Blood Tests
Lab charges often show up as separate line items from your doctor visit. These codes cover the most common blood draws and tests you'll see on a bill.
Imaging & Radiology
X-rays, MRIs, CT scans, and ultrasounds are some of the most expensive items on a medical bill. Prices vary dramatically by facility — the same MRI can cost $500 or $5,000.
Therapy & Behavioral Health
Therapy sessions are billed by duration. Make sure the code on your bill matches the actual length of your session — a 45-minute session should not be billed as a 60-minute one.
Heart & Cardiology
Heart tests like EKGs and echocardiograms are common additions to a checkup or ER bill. Know what each test does and what it typically costs.
Procedures & Surgery
From colonoscopies to knee surgery — these are higher-cost procedures where understanding the billing can save you hundreds or thousands of dollars.
Physical Therapy
Physical therapy is billed in 15-minute increments. Watch for "unbundling" — where a single session gets split into multiple line items that inflate the total.
Telehealth & Injections
Phone consultations and injections round out common billing items. Telehealth visits should generally cost less than in-person visits — check that your bill reflects this.
Skin & Dermatology
Skin biopsies, wart removals, and precancer treatments are common dermatology charges. Make sure the number of lesions on your bill matches what was actually treated.
Pregnancy & Obstetrics
Delivery bills are among the most expensive you'll encounter. These "global" codes bundle prenatal, delivery, and postpartum care — make sure you're not being double-billed for individual visits.
Breathing & Pulmonary
Breathing tests and nebulizer treatments are common for asthma, COPD, and respiratory infections. These are often add-ons to an ER or office visit bill.
How to Read Your Medical Bill
Find the CPT codes. Every medical bill lists procedure codes — usually 5-digit numbers. These are CPT codes, and they describe exactly what service was performed.
Look up each code above. Check if the description matches what actually happened during your visit. A "complex office visit" (99215) when you had a 10-minute check-up is a red flag.
Compare to typical costs. Each code has a Medicare rate and a typical charge range. If your charge is far above the range, ask your provider to explain.
Watch for high-error codes. Codes marked with a yellow dot above have higher rates of billing errors. Pay extra attention to these.
