Kaiser Permanente is investigating a flurry of medical bills it erroneously sent out to patients.

Kaiser officials say accounting problems caused an unknown number of patients to get bills for medical services they never received.

Patients were further stunned because the notices gave them just a few days to pay.

Kaiser has set up a number for patients with this problem: 1-800-201-2123
