Cal. Code of Regs., tit. 8, § 10152
A disability is considered permanent when the employee has reached maximum medical improvement, meaning the condition is well stabilized and unlikely to change substantially in the next year with or without medical treatment.
Applied to evaluate Dr. Steinman's MMI opinion and disability status.
From the decision · page 5A disability is considered permanent when the employee has reached maximum medical
improvement, meaning his or her condition is well stabilized, and unlikely to change substantially
in the next year with or without medical treatment. (Cal. Code of Regs., tit. 8, § 10152.)
Zemke v. WCAB (1968) 33 CCC 358
A medical opinion must disclose the underlying basis for its conclusions to constitute substantial evidence.
Applied to assess the sufficiency of Dr. Steinman's opinion.
From the decision · page 6To the contrary, Petitioner states that the Applicant's left shoulder clearly has been stabilized for
well over a year, even without treatment, given that the Applicant had already been nearly 1 year
and 7 months removed from his last date of work; to support this conclusion, she relies upon the
fact that Applicant had not sought any medical treatment and that Applicant only had minimal
findings that resulting in of 2% whole person impairment. (Defendant's Petition, page 7, lines 14-
16.) However, Petitioner has neither established herself as a medical expert so as to definitively
conclude that Applicant's left shoulder has stabilized nor provided any authority that would
suggest that a "relatively" low whole person impairment rating directly correlates to an injured
worker's temporary disability status. More significantly, the Petitioner has not directed the Court's
attention to any medical reports within the admitted record that would explain how and why the
Applicant's left shoulder has stabilized beyond the following conclusory statement by Dr.
Steinman: "It is my opinion this patient has reached the point of maximum medical improvement."
And a medical opinion must disclose the underlying basis for its conclusions in order to constitute
substantial evidence. (Zemke v. WCAB (1968) 33 CCC 358, 361.)
Labor Code §§ 5903, 5952; Garza v. Workmen's Comp. App. Bd. (1970) 3 Cal.3d 312
An award, order, or decision by the WCAB must be supported by substantial medical evidence in light of the entire record.
Applied to evaluate medical evidence for temporary disability.
From the decision · page 6An award, order, or decision by the WCAB must be supported by substantial medical evidence in
light of the entire record. (Lab. Code § 5903, 5952; Garza v. Workmen's Comp. App. Bd. (1970)
3 Cal.3d 312, 317-319; LeVesque v. Workmen's Comp. Appeals Bd. (1970) 1 Cal.3d 627, 635-
637.) To be substantial medical evidence, a medical opinion must be framed in terms of reasonable
medical probability, it must not be speculative, it must be based on pertinent facts, an adequate
examination and history, and it must set forth reasoning in support of its conclusions. (Granados
v. Workers' Comp. Appeals Bd. (1970) 69 Cal.2d 399; McAllister v. Workmen's Comp. Appeals
Bd. (1968) 69 Cal.2d 408; Escobedo v. Marshalls (2005) 70 Cal. Comp. Cases 604 (Appeals Board
en banc).)
Garza v. Workmen's Comp. App. Bd. (1970) 3 Cal. 3d 312
The test of substantiality must be measured on the basis of the entire record, rather than isolating evidence that supports the board and ignoring other relevant facts.
Applied to weigh medical evidence in context of entire record.
From the decision · page 7The test of substantiality must be measured on the basis of the entire record, rather than by simply
isolating evidence, which supports the board and ignoring other relevant facts of record which
rebut or explain that evidence. (Garza, supra, 3 Cal. 3d at 503.)

When independent injuries result in concurrent periods of temporary disability, the 104-week, two-year limitation under Labor Code section 4656(c)(1) runs concurrently.
Applied to determine concurrency of temporary disability periods.
From the decision · page 7When independent injuries result in concurrent periods of temporary disability, the 104-week, two-
year limitation under Labor Code section 4656(c)(1) likewise runs concurrently. (Foster v. WCAB
