Chemeo Transport, Inc. (Chemeo) appeals the trial court's judgment awarding James Conn (Conn) damages for loss of his motor vehicle, loss of use of his motor vehicle and personal injuries. We reverse the awards for the loss of use and for the value of the motor vehicle. We affirm the award for personal injuries.
On September 28, 1982, Conn was driving his 1977 International tractor with trailer attached west on U.S. Highway 224 in Wells County. Conn struck a trailer, owned by Chemco and driven by one of Chemeo's employees, as it was backing onto the highway in order to turn around. Conn's tractor was totalled. Conn suffered cuts from flying glass and was taken to the Caylor-Nickel Clinic in Bluffton where he was treated and released. Subsequently, Conn began experiencing pain in his legs and back and he sought treatment from several doctors.
Following the accident, Conn entered into arbitration proceedings with his insurance carrier, Protective Insurance Company (Protective). Following arbitration, Conn received from Protective $40,500 for the value of the tractor and $2,500 for partial loss of use. At the time of the settlement, Conn signed a release in which he acknowledged Protective's right of subrogation and agreed to "take no action which would jeopardize the right of subrogation of the Protective Insurance Company to recover damages which Protective Insurance Company has paid to James Conn for damages to and loss of use of the 1977 International Tractor...." Record at 105.
Conn filed this action in the Cass Circuit Court on March 9, 1983, seeking damages *1113 from Chemeo for loss of the tractor, loss of its use and personal injuries. On September 27, 1984, Protective, pursuant to its right of subrogation, filed suit against Chemeo, with Conn also named as a plaintiff, in Marion County Superior Court seeking the same damages as sought by Conn in the Cass County action. The Marion County action was dismissed with prejudice on January 7, 1985. Based on the dismissal, Chemeo moved for summary judgment in the Cass Cireuit Court on the questions of damages for the loss of the tractor and damages for loss of use. The trial court denied Chemco's summary judgment motion and the jury returned awards of $33,-000 for the loss of the tractor, $30,000 for loss of use, and $27,000 for personal injuries. Chemeco then perfected this appeal.
Chemeo first argues that the Marion County Superior Court dismissal with prejudice was res judicata as to the issues of damages for loss of the tractor and loss of its use in the Cass Circuit Court action. The doctrine of res judicata prevents relit-igation of an issue where there has been a final adjudication on the merits of the same issue between the same parties. Gayheart v. Newnam Foundry Co., Inc. (1979)
Conn's argument that he was not a real party in interest to the Marion County action is based upon the fact that the action was actually brought by Protective pursuant to its right of subrogation. "In the Marion County case, Conn was named as a Plaintiff by Protective only through their right of subrogation and in no manner did Conn authorize the suit." Appellee's Brief at 17. However, as Conn apparently concedes, Protective did have the right, by way of its subrogation claim, to name Conn as a plaintiff in the Marion County action. Conn was a party of record in the Marion County action, and the parties of record are bound for the purposes of res judicata. Moxley v. Indiana National Bank (1982) 4th Dist.Ind.App.,
Conn's argument that the Marion County court was not a court of competent jurisdiction is premised upon the fact that the Cass County case was filed eighteen months pri- or to the filing of the Marion County action. In order to properly address Conn's argument, it is necessary to distinguish between subject-matter jurisdiction and jurisdiction of the particular case.
"*'... The subject matter of an action, when reference is made to matters of jurisdiction, means the nature of the action and the relief sought. If the court has jurisdiction of the class of actions to which the particular case under consideration belongs it has jurisdiction of the subject matter of the action. If the court does not have jurisdiction of the class of actions, the parties cannot confer such jurisdiction. The phrase 'subject matter of the action' is sometimes used to refer to the thing involved in a particular case but such is not its meaning when *1114 used in the rule regarding jurisdiction. (original emphasis)

... Jurisdiction of the particular case is different than jurisdiction of the subject-matter, although occasionally the courts speak of jurisdiction of the subject- matter of the particular case. A court may have jurisdiction of the subject-matter, that is, of the general class of cases to which the particular case belongs, but not jurisdiction of the particular case. Jurisdiction of the particular case may be given by consent, either express or implied'" Farley v. Forley (1973) 2d Dist.,157 Ind.App. 385 , 397-8,300 N.E.2d 375 , 383, quoting 1 Wiltrout, Indiana Practice § 122.
A judgment rendered by a court lacking subject-matter jurisdiction is void and may be attacked at anytime. In Re Chapman (1984) 3d Dist.Ind.App.,
Both the Marion County Superior Court and the Cass Circuit Court had jurisdiction over the class of actions to which the case at bar belongs. See 1.0. 88-4-4-3 (Burns Code Ed.Repl. 1985), 838-5-85.1-4 (Burns Code Ed.Supp. 1986). Conn's filing of his case in Cass County did not deprive the Marion County Superior Court of its ability to hear similar cases involving similar claims. By filing his cause of action in Cass Circuit Court, Conn vested exclusive jurisdiction of the porticular case in the Cass Circuit Court. See State ex rel. International Harvester Co. v. Allen Circuit Court (1976)
The requirements for the application of the doctrine of res judicata have been met in this case. The Marion County Superior Court was a court of competent jurisdiction and its dismissal was on the merits. Conn was a party of record in the Marion County action, and the issues of damages for the value of the tractor and damages for the loss of the tractor's use were present in both the Marion County and the Cass County actions. Conn may not relitigate these issues in the Cass County action.
Because we have determined that the Marion County dismissal with prejudice was res judicata as to the issues of damages for the tractor and damages for the loss of the tractor's use, we need not address Chemeo's argument that the trial court considered improper evidence and applied an inappropriate standard in determining the loss of use damages. We move then to Chemeo's argument that the trial court improperly admitted evidence of Conn's medical expenses as a result of the accident.
At trial, Conn was allowed to introduce into evidence a series of medical bills which he testified were incurred as a result of the accident. Chenico argues that Indiana law requires a showing of reasonableness and necessity before medical bills may be admitted as evidence and cites several Indiana cases supporting its proposition. We disagree with Chemeo's interpretation of those cases.
Chemeco cites City of Bedford v. Woody (1899)
The other cases cited by Chemeo in its brief do not address the question of the admissibility of the medical bills but rather the question of the proper measure of damages for medical expenses. See Herrick v. Sayler (1958) N.D.Ind.,
'[T)he law of Indiana will allow a plaintiff to recover neither the actual amount of medical bills charged to him nor the amount of medical bills paid by him, but rather, the reasonable and fair value of medical expenses necessarily incurred by him. The actual amount charged to the plaintiff or the amount actually paid by him may tend to prove the reasonable and fair value of the services rendered to him but are not conclusive on the issue." Id. at 29 (emphasis added).
Thus, the law in Indiana is not that medical bills must be shown to be reasonable and necessary before they are admissible, but that only reasonable and necessary medical expenses may be recovered.
Admissibility of evidence is, first and foremost, a question of relevancy. "When evidence is relevant, it should be admitted regardless of its weight." McMahan v. Snap On Tool Corp. (1985) 4th Dist.Ind.App.,
In this case, the material fact to be proved was the reasonable and necessary medical expenses incurred by Conn as a result of the accident. The actual amount paid by Conn, as shown by his medical bills, tended to prove the reasonableness component of the standard. Thus, the medical bills were relevant and were properly admitted.
We emphasize that, in this case, we are concerned only with the question of admissibility. Chemco has not challenged the sufficiency of the evidence supporting the award of damages for medical expenses. Chemeo only challenges the admissibility of the medical bills. Thus, we need not determine whether the medical bills alone were sufficient to prove Conn's reasonable and necessary medical expenses. 1
Chemco next argues that the trial court erred in admitting a memoran
*1116
dum of the Industrial Board indicating a payment of $3,500 to Conn from his workmen's compensation carrier. The memorandum was included in Conn's Exhibit # 8, which also included the medical bills objected to by Chemeo. However, while Chemeo objected to the admission of the medical bills, it made no objection to the admission of the memorandum. A specific objection must be made when evidence is offered for admission in order to preserve an error for review. Ind. Tri-City Plaza Bowl, Inc. v. Estate of Glueck (1981) 3d Dist.Ind.App.,
Finally, Chemco argues that the trial court improperly questioned witnesses. A trial court may direct questions to a witness to aid in the fact-finding process so long as such questioning is done in an impartial manner and the defendant is not prejudiced. Posey County v. Chamness (1982) 1st Dist.Ind.App.,
The trial court's award for personal injuries is affirmed. The trial court's award of damages for loss of the tractor and its award for loss of the tractor's use are reversed, and the cause is remanded to the trial court with instructions to enter judgment for Chemco upon those two issues.
Costs are hereby assessed against appel-lee James J. Conn.
Notes
. However, we note that there is Indiana authority indicating that medical bills alone are sufficient to establish reasonable medical expenses. See Summers v. Tarney (1889)
