Functional Neurologic Status - Karnofsky Performance Scale (KPS)


**Note 1**: The Karnofsky Performance Scale (KPS) allows patients to be classified according to their functional impairment. This classification can be used to compare effectiveness of different therapies and to assess prognosis for individual patients. The lower the Karnofsky scale value, the worse the predicted survival for most serious illnesses. **Note 2**: Record the KPS only as specifically documented in the patient's record by the physician. Do not attempt to determine the KPS from other information in the record. If the KPS value is expressed in terms of a range, use the higher value. For example, use code 80 if the physician states "The patient's Karnofsky score is between 70 and 80". **Note 3**: For reference only, the classification scale is listed here: 0 Dead 10 Moribund, fatal processes progressing rapidly 20 Very sick, hospitalization necessary; active supportive treatment necessary 30 Severely disabled; hospitalization is indicated although death not imminent 40 Disabled; requires special care and assistance 50 Requires considerable assistance and frequent medical care 60 Requires occasional assistance, but is able to care for most personal needs 70 Cares for self; unable to carry on normal activity or do active work 80 Normal activity with effort; some signs or symptoms of disease 90 Able to carry on normal activity; minor signs or symptoms of disease. 100 Normal; no complaints; no evidence of disease **Note 4**: In CS Version 2, V0201 and V0202, the range of codes 000-100 was shown in a single row in this table. This range code has been replaced by specific codes for the 11 allowable KPS values described in Note 3. Any case with a different code must be reviewed and recoded in CS Version 2, V0203.
