Dr. Cassandra Lange, MD, FAAOS

Picture of Dr. Lange and her husband

Dr. Lange grew up in Cascade, Iowa. She graduated from Loras College in Dubuque, and married her husband David that same year. They both attended the University of Illinois, David is a veterinarian, and they have 5 children, whom they are extremely proud of, because they are good people. And as of this writing have 2 cats, 2 very pampered chickens, 2 horses, a donkey named Rosey, two sheep guardians named Merry and Pippin, and 50 sheep.

Dr. Lange completed a residency in Family Medicine, drawn to the breadth of that specialty and the long-term relationships with patients. It soon became apparent that a surgical specialty was where her heart was, and orthopaedics incorporated those aspects that drew her to primary care, maintaining wellness, and long-term relationships, only with power tools 🙂

patient information

Accepted Insurance

We accept most major insurances. Please have your insurance information handy when you call so we can verify we are in network.

New Patient forms

If you are a new patient we will have a few short forms for you to fill out in the waiting room prior to your first appointment.  Please arrive 20 minutes before your appointment time to allow time to fill out the forms.

Payment Policies

  • Co-pays, co-insurance, deductibles, and other fees for which you are responsible are due at the time of your appointment.

  • Self-pay services must be paid in full prior to treatment. A reasonable estimate will be provided at this time and any excess amount collected will be refunded.

  • You may make payments by credit card, cash, or check. Returned checks will result in a $25 fee billed to your account.

  • If you require assistance making the necessary payments, please let our staff know as soon as possible to determine if a payment plan can be arranged.

Insurance Policies

  • Your insurance plan is a contract between you and your insurance provider. We will file claims on your behalf for those insurers with whom we contract, assuming you have assigned benefits to your physician.

  • If your insurance provider fails to make payments within a timely period (60 days), payment in full is expected from the patient or responsible party.

  • Failure to respond to an insurer’s request for information can result in claim denial. Should this occur, the account balance will become the immediate responsibility of the patient.

  • Co-insurance and deductibles for procedures are due when the procedure is scheduled.

  • Certain contracts provide for a global period of care associated with certain procedures. Return visits to the physician during this period are provided without charge. Other services provided during the global period, including additional procedures, X-rays, cast/splint changes, braces and medical supplies are associated with additional fees.

  • Evaluation of new or separate problems is not covered by the global period.

  • Fracture treatment may be billed as a procedure and therefore subject to deductibles, co-insurance and a global period in the same manner as surgical treatment.
