We measure the time-dependent CP asymmetry in B-0 -> K-S(0)pi(0)gamma decays for two regions of K-S(0)-pi(0) invariant mass, m(K-S(0)pi(0)), using the final BABAR data set of 467x10(6) B(B)overbar pairs collected at the PEP-II e(+)e(-) collider at SLAC. We find 339 +/- 24 B-0 -> K-*0 gamma candidates and measure S-K(*)gamma=-0.03 +/- 0.29 +/- 0.03 and C-K(*)gamma=-0.14 +/- 0.16 +/- 0.03. In the range 1.1 < m(K-S(0)pi(0))< 1.8 GeV/c(2) we find 133 +/- 20 B-0 -> K-S(0)pi(0)gamma candidates and measure S-KS(0)pi(0)gamma=-0.78 +/- 0.59 +/- 0.09 and C-KS(0)pi(0)gamma=-0.36 +/- 0.33 +/- 0.04. The uncertainties are statistical and systematic, respectively.
