Q:I am a relatively new prosthetist and was wondering if Medicare will cover repairs or adjustments made to a patient's prosthesis?

A: Any repairs or adjustments made to the prosthesis within the first 90 days of fitting are not paid for separately; Medicare considers that as included in the reimbursement for the prosthesis. After the initial 90 days, you would then use either L-7510 (repair) and/or L-7520 (labor per 15 minutes).

You will need to explain to Medicare in your additional documentation exactly what the repairs were for. Remember to always use the proper modifiers: RP (repair); RT or LT (specifies which leg); K1, K2, K3, or K4 (what functional level).

Q:Can you help me settle a dispute between myself and a colleague? How long is a provider required to keep proof-of-delivery documentation on file?

A: According to DMERC, suppliers are required to maintain proof of delivery documentation in their files for seven years.

Q:I billed a breast prosthesis to Medicare for the first time, and my claim was denied for CO-16. I contacted Medicare and was told my claim was missing the appropriate modifier. Which modifier do I use?

A: When billing for a breast prosthesis, you must use either the RT (right) or LT (left) modifier. If the patient had a bilateral mastectomy, you must use both modifiers on one line item and your number of units should be two.
