In an effort to improve the therapy payment system, Medicare now requires that Functional Reporting be completed for all Part B outpatient therapy claims for physical therapy (PT), occupational therapy (OT), and speech-language pathology (SLP) services regardless of practice setting. Section 3005 (g) of the Middle Class Tax Relief and Jobs Creation Act (MCTRJCA) amended Section 1833 (g) of the Social Security Act to require a claims-based collection system for outpatient therapy services. A six month testing period ran from January 1, 2013 to June 30, 2013. The July 1, 2013 deadline for Functional Reporting on claims has passed and if practitioners are not submitting G-codes with the respective severity modifiers they are or will begin seeing claim rejection letters.
Functional Limitation Reporting under Medicare presents a significant challenge to health care practitioners. The coding is complex and burdensome. However, for reimbursement purposes it is essential not only to include G-codes and severity modifiers on claims, but also to understand the complexities of coding.
For claims submission, practitioners must continue to report a nonpayable therapy code unless a beneficiary is under a home health plan of care (POC) (GP for a PT POC; GO for an OT POC; and GN for a SLP POC). Practitioners must also now report a G-code from 42 different Functional Limitation G-codes. These include six sets for PT and OT combined and eight sets for SLP services. The G-code sets contain the beneficiary’s current status, projected goal status, and a discharge status. The practitioner selects the G-code set that most closely relates to the primary functional limitation being treated regardless of discipline. The practitioner should choose the G-code set that is most clinically relevant to a successful outcome; would yield the quickest / greatest functional progress; or reflects the greatest priority for the beneficiary. Finally, “Other PT/OT/SLP” code sets should be used when one of the other sets do not describe the functional limitation.
Along with these G-codes, reporting requires the inclusion of severity modifiers for the functional limitation. The severity modifiers must reflect the beneficiary’s percentage of functional impairment. There are seven modifiers ranging from 0 percent impaired to 100 percent impaired (e.g., CH – 0 percent impaired; CN – 100 percent impaired). The practitioner should use a score from any functional assessment tool to assess severity, and clinical judgment should be used to assign the appropriate modifier. As an example, a practitioner may choose a CH modifier to indicate that the services are not intended to treat a functional limitation. The same modifier may be used for projected goal status and current status where the practitioner does not expect improvement (e.g., maintenance therapy).
G-codes and modifiers must be reported: 1) at the outset of a therapy episode of care; 2) at least once every ten (10) treatment days (coinciding with progress reporting period); 3) when an evaluative procedure is furnished and billed (e.g., billing of Current Procedural Terminology (CPT) codes 92506; 97001; 97002); 4) at the time of discharge from the therapy episode of care; 5) at the time where the reporting of a functional limitation is ended and need for further therapy is necessary; and 6) at the time reporting is begun on a different function limitation within the same episode of care. Generally, one functional limitation should be reported at a time, except where the beneficiary has reached the goal or progress set on the initially reported function limitation, but the need for treatment continues. A second functional limitation reporting would then be required using another set of G-codes, resulting in two or more functional limitations during one therapy episode of care.
Beyond these requirements, it is also imperative that practitioners document how a reporting decision was made so that the same decision making process can be used at the next assessment interval. As always, documentation to reflect accurate billing, coding and functional reporting is crucial to avoid claims being rejected and/or subsequent audits.
