Lab. Code, 5952(d)
An award, order, or decision of the Appeals Board must be supported by substantial evidence.
The WCJ's denial was based on lack of substantial medical evidence.
From the decision · page 2An award, order, or decision of the Appeals Board must be supported by substantial
evidence. (Lab. Code, § 5952(d); Lamb v. Workmen's Comp. Appeals Bd. (1974) 11 Cal.3d 274,
281 [39 Cal.Comp.Cases 310]; Garza v. Workmen's Comp. Appeals Bd. (1970) 3 Cal.3d 312, 317
[35 Cal.Comp.Cases 500].) To be substantial evidence a medical opinion must be based on
pertinent facts, on an adequate examination and an accurate history, and it must set forth reasoning
in support of its conclusions. (Escobedo v. Marshalls (2005) 70 Cal.Comp.Cases 604 (Appeals
Board en banc).) Review of the trial record indicates that PTP Dr. Green did not address the cause
of applicant's orthopedic symptoms in any of his reports admitted into evidence. (See App. Exhs.
1, 2, and 3.) In his initial report Dr. Komberg stated:
Escobedo v. Marshalls (2005) 70 Cal.Comp.Cases 604 (Appeals Board en banc)
A medical opinion must be based on pertinent facts, an adequate examination and an accurate history, and must set forth reasoning in support of its conclusions.
The reports from PTP and secondary treating physician did not meet these requirements and were rejected as substantial evidence.

Insurance Company of North America v. Workers' Comp. Appeals Bd. (Kemp) (1981) 122 Cal.App.3d 905 [46 Cal.Comp.Cases 913]
A finding of cumulative injury must be based on expert medical opinion.
Applicant's trial testimony alone was not substantial evidence of cumulative injury AOE/COE.
From the decision · page 3The reports from Dr. Green and Dr. Komberg do not comply with the requirements as described
in Escobedo v. Marshalls, supra, and do not constitute substantial evidence. Also, a finding that
an applicant sustained a cumulative injury must be based on an expert medical opinion. (See
Insurance Company of North America v. Workers' Comp. Appeals Bd. (Kemp) (1981) 122
Cal.App.3d 905 [46 Cal.Comp.Cases 913].) Where issues exist regarding diagnosis, prognosis or
treatment that is beyond the bounds of ordinary knowledge, medical proof is required. (See
Bstandig v. Worker's Comp. Appeals Bd. (1977) 68 Cal.App.3d 988, 996 [42 Cal.Comp.Cases
114].) Thus, applicant's trial testimony is not substantial evidence as to the issue of whether
applicant sustained a cumulative injury AOE/COE.
Bstandig v. Worker's Comp. Appeals Bd. (1977) 68 Cal.App.3d 988, 996 [42 Cal.Comp.Cases 114]
Medical proof is required where issues regarding diagnosis, prognosis or treatment are beyond ordinary knowledge.
Applicant's trial testimony was insufficient to establish injury AOE/COE without medical proof.
From the decision · page 3The reports from Dr. Green and Dr. Komberg do not comply with the requirements as described
in Escobedo v. Marshalls, supra, and do not constitute substantial evidence. Also, a finding that
an applicant sustained a cumulative injury must be based on an expert medical opinion. (See
Insurance Company of North America v. Workers' Comp. Appeals Bd. (Kemp) (1981) 122

applicant sustained a cumulative injury AOE/COE.
Del Rio v. Quality Hardware (1993) 58 Cal.Comp.Cases 147 (Appeals Board en banc)
If the injury claim is denied, it is appropriate to obtain a medical-legal report to determine injury AOE/COE.
The Appeals Board ordered further medical-legal evaluation to properly litigate the injury AOE/COE issue.
From the decision · page 4determine that a claim is or is not barred by the post termination defense, an initial finding of injury
AOE/COE must be made. In turn, it is appropriate when there is a disputed injury claim, to have
applicant undergo a medical-legal evaluation. Otherwise stated, if the injury claim is promptly
accepted, there is no necessity for a medical-legal report, but if the claim is denied it is appropriate
that a medical-legal report be obtained. (Del Rio v. Quality Hardware (1993) 58 Cal.Comp.Cases
147 (Appeals Board en banc).) Here, without a medical-legal examination/report, there is
insufficient evidence in the record upon which the issue of injury AOE/COE may be determined.
