AI Analysis

Under CA Labor Code §4628(b), the AME's opinion (Dr. Singh, 35% WPI) is generally controlling where parties agreed to an AME panel. The 23-point spread between PTP (22%) and QME (45%) opinions elevates dispute risk significantly. Dr. Singh's 15% apportionment to pre-existing condition will reduce the final PD award. Confirm AME agreement status before proceeding to MSC.

AI Analysis

The L4–L5 disc herniation (M51.16) is the primary compensable injury and the basis for the permanent disability dispute. The right knee contusion resolved without permanent impairment. No additional diagnoses were raised by any provider. The QME's DRE Lumbar Category IV classification (vs. PTP's Category II) is the root cause of the WPI conflict.
