Criteria: Table 16-10 Determining Impairment of the Upper Extremity Due to Sensory Deficits or Pain Resulting from Peripheral Nerve Deficits (482), Table 16-15 Maximum Upper Extremity Impairment Due to Unilateral Sensory or Motor Deficits or to Combined 100% Deficits of the Major Peripheral Nerves (492),Table 16-11 Determining Impairment of the Upper Extremity Due to Motor and Loss-of-Power Deficits Resulting from Peripheral Nerve Disorders Based on Individual Muscle Rating (484).
Guidance: Rate per Section 16.5d Impairment Rating of Entrapment / Compression Neuropathies (491-495). According to Table 16-15 Maximum Upper Extremity Impairment Due to Unilateral Sensory or Motor Deficits or to Combined 100% Deficits of the Major Peripheral Nerves (492) the maximum loss for the ulnar nerve is 7% upper extremity impairment for sensory deficits and 36% upper extremity impairment for motor deficits. Sensory deficits are graded by Table 16-10 Determining Impairment of the Upper Extremity Due to Sensory Deficits or Pain Resulting from Peripheral Nerve Deficits (5th ed., 482) If the entire ulnar nerve is involved this sensory deficit is multiplied by the maximum loss of 7% upper extremity impairment. Motor deficits are graded by Table 16-11 Determining Impairment of the Upper Extremity Due to Motor and Loss-of-Power Deficits Resulting from Peripheral Nerve Disorders Based on Individual Muscle Rating (484). If the entire ulnar nerve is involved this motor deficit is multiplied by the maximum loss of 36% upper extremity impairment. These impairments are combined.
