Criteria: Table 15-3 Wrist Regional Grid: Upper Extremity Impairments (395-397), 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). Diagnosis is specified in Table 15-3 (396) under the Category of “Ligament / Bone / Joint”. 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 more than 1 diagnosis can be used, the highest causally-related impairment should be used. In rare case, if significant, consistent motion impairment deficits that result in greater impairment rate via Range of Motion. Figure 15-2 (388) summarizes findings.
