Spinal Cord Stimulator Revision Coding

I have a scenario that I'm not sure of.

Patient has had a spinal cord stimulator trial. Trial has two arrays stimulating the cervical area. The current battery accommodates two arrays.

The provider will be doing a permanent implant in an outpatient care setting. When the provider does the permanent implant, provider will be removing the current battery and replacing with a battery that will accommodate 4 arrays. MD will use the same two leads for the cervical area and add two additional for the lumbar area.

We normally bill

63650

63650-59

63685

95972

Any suggestions on the new scenario?
