for which Chapman was compensated and the subsequent aggravation of that injury by the mismatch of Chapman’s blood are separate and distinct injuries. The second injury, according to appellees, is governed strictly by the provisions of § 59-10-19.-1(B), supra, and not by § 59-10-25(C), supra.
In considering the validity of appellees’ argument we look to another section of the Workmen’s Compensation Act, § 59 — 10— 4(D), N.M.S.A.1953 (2d Repl.Vol. 9, pt. 1, 1974), which provides, in part:
"Nothing in the Workmen’s Compensation Act, however, shall affect, or be construed to affect, in any way, the existence of, or the mode of trial of, any claim or cause of action which the workman has against any person other than his employer, or another employee of his employer, including a management or supervisory employee, or the insurer, guarantor or surety of his employer.”
Section 59 — 10—19.1 (B), supra, obviously relates to torts of persons other than the employer, or another employee of the employer, or the insurer, guarantor or surety of the employer. Under certain specified circumstances, it extends the tort liability of the employer beyond that recognized in the law of torts, upon an election by the employee, but it in no way affects the tort liability of third persons furnished by the employer to render reasonable medical and hospital services to the injured employee. Normally, under the law of torts, absent a contractual or statutory obligation to furnish medical or hospital services, an employer is not liable for furnishing such services to employees. However, many cases, and we believe the better reasoned, place upon the employer in this situation the duty to use due care in selecting the doctor and hospital. Beyond this there is no liability of the employer for the tortious conduct of the doctor or hospital. Compare Annot., 16 A.L.R.3d 564 (1967) with Annot., 127 A.L.R. 1108 (1940) and Annot., 28 A.L.R.3d 1066 (1969).
However, § 59-10-19.1 (B), supra, extends this tort liability of the employer to cover the tortious conduct of the doctor and hospital, if the employer has made provisions for medical and hospital care of the employee at the time of the accident out of which arises the employee’s rights to compensation and medical and hospital care under the Workmen’s Compensation Act. Section 59-10-19.1 (B), supra, nowhere requires the employer to furnish either compensation or medical or hospital care for the employee as a result of the injuries he sustains by reason of this subsequent tor-tious act of the doctors or the hospital. It provides that the employee may elect to hold the employer responsible for the injuries he sustains as a result of this subsequent tortious conduct, and, if he so “elects to hold the employer liable for the injuries, the cause of action of the workman against the third person * shall be assigned to the employer, who may institute proceedings thereon in any court having jurisdiction, in the workman’s name.” This is not a subrogation to the extent of any amounts the employer may have paid. The entire cause of action of the injured workman is assigned to the employer and the injured workman may look to the employer for damages for his injuries, and not for benefits under the Workmen’s Compensation Act. The entire tenor of this statute relates to a shifting of tort liability from the tort-feasor to the employer under the circumstances prescribed and upon the election by the employee in the manner provided.
In our opinion, this rather unusual section of our Workmen’s Compensation Act, coupled with the foregoing quoted provisions from § 59-10-4(D), and the previously discussed provisions of § 59-10-25(C), clearly demonstrate a legislative intent that ordinary tort law, except as modified by said §§ 59-10-19.1 (B) and 59-10-25(C), shall govern the tortious acts of medical personnel and hospitals charged with the care and treatment of an employee for an accident sustained by him
