Short answer. Yes. Article 235 of the Revised Penal Code imposes the maltreatment penalty on the officer in addition to his liability for the physical injuries or damage caused — so a guard who maltreats a detainee faces separate, additional liability for whatever physical injuries result, on top of the maltreatment penalty itself.

Liability for injuries is explicitly separate
Article 235 imposes its penalty in addition to his liability for the physical injuries or damage caused, upon any public officer or employee who overdoes himself in the correction or handling of a prisoner or detention prisoner, by imposing punishments not authorized by the regulations or inflicting them in a cruel and humiliating manner. The article's own wording keeps liability for the resulting physical injuries distinct from, and additional to, the maltreatment penalty itself.
The aggravated version, for extorting a confession
The article sets a heavier penalty where the maltreatment's purpose is to extort a confession or obtain information from the prisoner: prisión mayor in its minimum period, temporary special disqualification and a fine not exceeding One hundred thousand pesos (₱100,000), in addition to his liability for the physical injuries or damage. Even in this more serious version, the article repeats the same structure — the officer's liability for physical injuries stands apart from, and alongside, the maltreatment penalty.
Why maltreatment and physical injuries are kept separate
Maltreatment under Article 235 punishes the abuse of the officer's position over a prisoner under his charge — the unauthorized or cruel manner of correction or handling itself. Physical injuries are a distinct harm the maltreatment may cause, and the article's repeated in addition to language means the officer does not get to treat the maltreatment penalty as covering the injury as well; both consequences are tracked and imposed separately.
The current fine amount
The ₱100,000 fine figure in the confession-extortion version reflects the amount as amended by Republic Act No. 10951, which revised fines throughout the Revised Penal Code in 2017. Older copies of the Code may show a different, lower original fine, so it is worth checking which version of the text a particular source is giving you before relying on the amount.
