Criteria: Table 15-2 Digit Regional Grid: Upper Extremity Impairments (391-394), Table 15-6 Adjustment Grid: Summary (406), Table 15-7 Functional History Adjustment: Upper Extremities (406), Table 15-8 Physical Examination Adjustment: Upper Extremities (408), Table 15-9 Clinical Studies Adjustment: Upper Extremities (410-411).
Accurately define diagnosis, and assess history, physical examination findings, and clinical studies, as explained in Section 15-1 (385-386). Impairment is based on Diagnosis-Based Impairment (DBI) and specific diagnoses associated with injury. Rate only for the most significant causally-related diagnosis for a digit. Assure accuracy of adjustment factors, net adjustment calculation, and grade modification. Impairment values are converted from UEI to WPI using Table 15-11 (420). Note revisions provided in “Corrections and Clarifications” (AMA Press, August 2008) on page 18 to Table 15-7 Functional History Adjustment and modifications to Section 15.3b explaining that if a physical finding is used to determine class placement that specific finding should not be considered again for adjustment. If consistent motion impairment deficits that result in greater impairment rate via Range of Motion. Figure 15-2 (388) summarizes findings. If multiple digits involved, convert digit to hand impairment using Table 15-12 (421-423) and add these hand equivalents. Hand impairment may be converted to whole person impairment using Table 15-11 (420). Figure 15-2 (388) summarizes findings.
