Functional Limitation Reporting, G-Codes & Severity Modifiers

The following information is for therapy G codes 2019.

The functional data reporting and collection system is effective for therapy services with dates of service on and after January 1, 2013. However, a testing period will be in effect from January 1, 2013, through June 30, 2013, to allow providers to use the new coding requirements in order to assure that their systems work. During this time period claims without G-codes and modifiers will be processed.

Effective for the dates of services from July 1, 2013 Medicare will begin returning and rejecting claims, as applicable, that do not contain the required functional G-code / modifier information.

Therapy G codes 2019 – Severity/Complexity Modifiers

For each non-payable G-code shown above, a modifier must be used to report the severity/complexity for that functional measure. The severity modifiers reflect the beneficiary’s percentage of functional impairment as determined by the therapist, physician, or NPP furnishing the therapy services. The beneficiary’s current status,
the anticipated goal status, and the discharge status are reported via the appropriate severity modifiers. The seven modifiers are defined in the following table:

CH – 0 percent impaired, limited or restricted

CI – At least 1 percent but less than 20 percent impaired, limited or restricted

CJ – At least 20 percent but less than 40 percent impaired, limited or restricted

CK – At least 40 percent but less than 60 percent impaired, limited or restricted

CL – At least 60 percent but less than 80 percent impaired, limited or restricted

CM – At least 80 percent but less than 100 percent impaired, limited or restricted

CN – 100 percent impaired, limited or restricted

Therapy G codes 2019 – Required Reporting of Functional G-codes and Severity Modifiers

The functional G-codes and corresponding severity modifiers listed above are used in the required reporting on specified therapy claims for certain Dates of Service (DOS). Only one functional limitation shall be reported at a given time for each related therapy plan of care (POC). However, functional reporting is required on claims throughout the entire episode of care; so, there will be instances where two or more functional limitations will be reported for one beneficiary’s POC, just not during the same time frame. In these situations, where reporting on the first reported functional limitation is complete and the need for treatment continues, reporting is required for a second functional limitation using another set of G-codes. Thus, reporting on more than one functional limitation may be required for some beneficiaries, but not simultaneously.

Specifically, functional reporting, using the G-codes and modifiers, is required on therapy claims for certain DOS as described below:

• At the outset of a therapy episode of care, i.e., on the DOS for the initial therapy service;

• At least once every 10 treatment days — which is the same as the newly-revised progress reporting period — the functional reporting is required on the claim for services on same DOS that the services related to the progress report are furnished;

• The same DOS that an evaluative procedure, including a re-evaluative one, is submitted on the claim (see below for applicable HCPCS/CPT codes);

• At the time of discharge from the therapy episode of care, if data is available; and,

• On the same DOS the reporting of a particular functional limitation is ended, in cases where the need for further therapy is necessary.
