While a medical expert need not be a specialist in a particular field in order to testify regarding accepted practices in that field, the witness nonetheless should be possessed of the requisite skill, training, education, knowledge, or experience from which it can be assumed that the opinion rendered is reliable. Where the witness opines outside his area of specialization, a foundation must be laid tending to support the reliability of the opinion rendered.
