Insurance not insuring

 Now, an update in our investigation in partnership with clear health costs into what women are paying for mammograms and other medical tests. We heard from hundreds of you, including breast cancer survivors who want to know why follow-up tests are sometimes not covered by insurance. It's another case of medical price roulette. And Anna Warner investigates. Kristen Hoffman fought breast cancer a year ago. Now she's battling to get her insurance company cigna to pay for her mammograms. You just feel like you're getting the runaround, and sometimes you don't have the bandwidth to fight the battle. The affordable care act requires insurance companies to pay for regular screening mammograms for women 40 and over, but many breast cancer survivors need diagnostic mammograms. Similar tests read more quickly and insurance companies often won't pay for them. I was got smacked when I got the bill. Her bill $470 for a test she needs every six months. This year she's out nearly $900. It doesn't seem that it's a fair process and not just as a breast cancer survivor, but as just a woman out there trying to get basic access to things we should not have to fight for. Other women told us similar stories with one breast cancer survivor writing, "Who has this kind of money?" It deters you from continuing with necessary follow up appointments and tests. That's really heart wrenching and heartbreaking that they're being put in the situation. Molly Guthrie with the Susan G Koman Foundation says her group has helped pass legislation in some states to expand coverage. They have to make a decision. Are they gonna feed their kids? Are they gonna pay their electric bill or they gonna get this exam that they know that they need? Most states don't have it. That doesn't seem right. It's all preventative. We're all in this together and everybody should get the equal services. Signal would not comment directly on Hoffman's case. It told us tonight that diagnostic tests are covered, but plans are not required under the affordable care act to cover 100% of the cost, which means the patient will often be footing some or all of that cost. And Nora, we want to remind viewers to share their medical pricing stories with us at CBS news dot com slash health costs or EMAIL health costs at CBS news dot com. I know you're reading those emails. Thank you Anna, for staying on this.
