Permanent Disability / WPI Rating
AI Analysis
Significant WPI conflict: PTP 22%, QME 45%, AME 35% — a 23-point spread. Under CA Labor Code §4628(b), the AME opinion (Dr. Singh, 35%) is generally controlling when parties agreed to the AME panel. Dr. Singh's 15% apportionment to pre-existing condition will reduce the final PD award. The carrier will likely argue for the PTP's lower rating; the applicant will argue QME. Recommend confirming AME agreement and preparing to defend the 35% figure at MSC.
Dr. Wu QME 3/8/24
Dr. Singh AME 4/2/24
Dr. A. Martinez PTP 11/14/23

Supporting Evidence
3 items
Dr. Wu QME Report — WPI 45%, DRE Lumbar Category IV
QME concluded 45% whole person impairment based on MRI findings of L4–L5 disc herniation with L5 nerve root compression and confirmed radiculopathy. DRE Category IV classification reflects significant neurological findings.
Dr. Singh AME Report — WPI 35%, DRE Lumbar Category III
AME confirmed permanent impairment at 35% with 15% apportionment to pre-existing degenerative condition. DRE Category III reflects objective findings without the level of neurological deficit documented by the QME.
MRI Report — L4–L5 disc herniation with moderate foraminal stenosis
Imaging confirms L4–L5 disc herniation with moderate right-sided foraminal stenosis and objective evidence of L5 nerve root compression, providing radiographic basis for impairment ratings above DRE Category I.

Dr. Angela Martinez PTP Report — WPI 22%, DRE Lumbar Category II
Treating physician rated 22% WPI at Category II — significantly lower than QME and AME. PTP noted "clinically mild radiculopathy" and attributed most functional limitation to pre-existing degenerative changes rather than the industrial injury.
Employer IME Report — No ratable permanent impairment
Employer's independent medical examiner (Dr. R. Hoffman, orthopedics) opined that the industrial injury caused only a temporary exacerbation of pre-existing degenerative disc disease with no resulting permanent impairment attributable to the work injury.
