Cost estimates

These ranges are network rate estimates across all the insurance plans that Dr. Hoelzer accepts.

Note: These are just estimates. We advise verifying the exact costs with your provider.

Mammogram (screening) $141 – 645

Amino’s cost estimates are estimates of the total amount that you and your health insurance company might pay for a procedure—this is what we call the “network rate”. Our cost estimates can help you prepare for the financial impact of medical care and help you make more confident decisions about where to get treated.

Same-day biopsy rate

Dr. Hoelzer’s same-day biopsy rate is similar to the rate we predicted for her mix of cases and patients.

same-day biopsy rate

As a patient, you may prefer a doctor who has a higher rate of same-day biopsy following mammogram, because early diagnosis of conditions detected by biopsy is important for effective treatment.

Decision factor

Compared to predicted rates calculated for each doctor’s unique mix of cases and patients

  • Lower than our predicted rate
  • Higher than our predicted rate
  • Similar to our predicted rate

When a breast tissue biopsy is indicated following a suspicious finding on mammogram, our data indicates that about a third of all biopsies occur on the same day. As a patient, you may prefer a doctor who has a higher rate of same-day biopsy following mammogram, because early diagnosis of conditions detected by biopsy is important for effective treatment.

To help you understand how Dr. Hoelzer’s rate of same-day biopsy for mammogram compares to a typical doctor who performs mammograms:

  1. We first measure the actual same-day biopsy rate for Dr. Hoelzer’s patients whose mammograms included a suspicious finding that merited a biopsy.
  2. We then analyze the typical practices of all other doctors in the United States who perform mammograms, using a data-driven model to predict the rate of same-day biopsy for patients like Dr. Hoelzer’s.

By comparing these two numbers, you can see whether Dr. Hoelzer’s rate of same-day biopsy is lower than, similar to, or higher than predicted.

This prediction adjusts based on the types of patients the doctor sees, so a doctor who treats sicker patients may have a different predicted rate than a doctor who treats healthier patients.
