By now, youíve probably heard plenty on the ins and outs of functional limitation reporting — everything from why an integrated functional limitation reporting solution is the best solution to how to incorporate G-codes and severity modifiers into your documentation workflow. Today, letís talk G-code basics.

What's a G-code?
Effective July 1, CMS will require therapists to complete functional limitation reporting through the use of new G-codes and corresponding severity modifiers for all eligible Medicare patients at the initial examination, at minimum every 10 visits (or progress note) and at discharge in order to receive reimbursement.

What are the severity modifiers?
With each G-code, use one of the following modifiers (in a seven-point scale) to report the severity and complexity for that functional limitation. You base this assessment on the score of an outcome measurement tool as well as your skilled clinical knowledge as a therapist.
In addition to reporting these new G-codes and modifiers, you must also include the therapy modifiers (GO, GP, and GN) to indicate that the therapy services are furnished under an OT, PT, or SLP plan of care, respectively.
