T85.42XA is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like displacement of breast prosthesis and implant. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

Patient Education


Breast Reconstruction

If you need a mastectomy, you have a choice about whether or not to have surgery to rebuild the shape of the breast. Instead of breast reconstruction, you could choose to wear a breast form that replaces the breast, wear padding inside your bra, or do nothing. All of these options have pros and cons. What is right for one woman may not be right for another.

Breast reconstruction may be done at the same time as the mastectomy, or it may be done later on. If radiation therapy is part of the treatment plan, your doctor may suggest waiting until after radiation therapy.

If you're thinking about breast reconstruction, talk to a plastic surgeon before the mastectomy, even if you plan to have your reconstruction later on.

A surgeon can reconstruct the breast in many ways. Some women choose to have breast implants, which are filled with saline or silicone gel. Another method uses tissue taken from another part of your body. The plastic surgeon can take skin, muscle, and fat from your lower abdomen, back, or buttocks.

The type of reconstruction that is best for you depends on your age, body type, and the type of cancer surgery that you had. A plastic surgeon can help you decide.
