¶1. John W. McDonough, D.O. (McDonough) requests review of a court of appeals' decision which held that an appeal of a necessity of treatment order must be served on the Department of Workforce Development (Department) and that service on the Labor and Industry Review Commission (Commission) was insufficient. The issue presented is whether McDonough, appealing a necessity of treatment order of the Department, can achieve service by serving the Commission rather than the Department with enough copies of the summons and complaint as there are defendants. We hold that, given the ambiguity presented by the interaction between the two statutes at issue, service for appeals from Department necessity of treatment orders can be achieved by timely serving either the Department or the Commission with enough copies of the summons and complaint as there are defendants. Because McDonough served enough copies of the summons and complaint with the Commission as there are defendants, we conclude that he achieved service. Accordingly, we reverse the decision of the court of appeals and remand the cause to the circuit court for proceedings on the merits.
¶ 2. McDonough provided medical services for a City of Wisconsin Rapids' (Wisconsin Rapids) employee who injured his shoulder while at work on November 17, 1995. Because the employee was injured while at work, his injuries were compensable under workers compensation, Wis. Stat. ch. 102. From January 3, 1996 through June 21, 1996, McDonough provided medical treatment to the Wisconsin Rapids employee. McDonough submitted a claim to Wisconsin Rapids' workers compensation insurance carrier, Wausau Business Insurance Company (Wausau Insurance). *275 Wausau Insurance refused to pay a portion of the claim, asserting that the treatment provided by McDonough after February 28, 1996, was not medically necessary.
¶ 3. In September 1996, McDonough filed a necessity of treatment dispute request with the Department 1 pursuant to Wis. Stat. § 102.16(2m) (1993-94). 2 On March 31,1997, the Department determined that the services provided by McDonough were not medically necessary. The order stated that it would become final within 30 days unless appealed to the circuit court pursuant to Wis. Stat. § 102.23(l)(a).
¶ 4. McDonough filed a summons and complaint with the Wood County Circuit Court on April 28,1997, within the 30 days allowed to seek judicial review. One copy of the authenticated summons and complaint was personally served on a Program Assistant in the Office of the Secretary of the Department on April 29, 1997; four copies were personally served on the Chairperson of the Commission on April 29, 1997; one copy was served by sheriff s service on the City Clerk of Wisconsin Rapids on April 30, 1997; and one copy was served by sheriffs service on a employee of the Legal Support Office at Wausau Insurance on May 5,1997.
¶ 5. The Department, Wisconsin Rapids, and Wausau Insurance moved to dismiss McDonough's claim for lack of subject matter jurisdiction, or competency to proceed, arguing that Wausau Insurance was not served with an authenticated summons and com *276 plaint within 30 days from the issuance of the Department's decision and order dated March 31, 1997, as required by Wis. Stat. § 102.23(l)(a). They argued that Wausau Insurance was a necessary and adverse party, and therefore, because McDonough failed to serve Wausau Insurance within 30 days after the Department's decision and order, the court had no subject matter jurisdiction to proceed. McDonough argued that service had been achieved on Wausau Insurance through timely service on the Commission, as required by the plain language of § 102.23(l)(b).
¶ 6. The Wood County Circuit Court, the Honorable Dennis D. Conway presiding, granted the defendants' motions and dismissed the case with prejudice. The circuit court determined that a necessary and adverse party, Wausau Insurance, had not been served within 30 days of the Department's order as required by Wis. Stat. § 102.23. Therefore, the circuit court determined that it did not have subject matter jurisdiction or competency to proceed.
¶ 7. McDonough appealed the circuit court's judgment pursuant to Wis. Stat. § 102.25. In an unpublished per curiam opinion, the court of appeals affirmed the circuit court's dismissal of McDonough's case. 3 The court of appeals determined that "department" should be read in place of "commission" throughout Wis. Stat. § 102.23 when a party is appealing a Department decision and order under Wis. Stat. § 102.16(2m)(e).
¶ 8. McDonough petitioned this court for review pursuant to Wis. Stat. § 808.10 and § (Rule) 809.62, which we granted.
*277 ¶ 9. The issue presented is whether a party appealing a necessity of treatment order of the Department pursuant to Wis. Stat. § 102.16(2m)(e) can achieve service by serving the Commission rather than the Department with enough copies of the summons and complaint as there are defendants. Section 102.16(2m)(e) states that judicial review of Department orders must be done in the same manner that compensation claims are reviewed under Wis. Stat. § 102.23. This issue requires that we interpret §§ 102.16(2m)(e) and 102.23(l)(b) and the interaction of these two statutes.
¶ 10. Statutory interpretation is a question of law that this court reviews de novo.
Jungbluth v. Hometown, Inc.,
¶ 11. Wisconsin Stat. § 102.16(2m)(e) provides: "A health service provider, insurer or self-insured employer that is aggrieved by a determination of the department under this subsection [regarding challenging a necessity of treatment dispute order] may seek judicial review of that determination in the same manner that compensation claims are reviewed under s. 102.23." At the direction of § 102.16(2m)(e), we turn to Wis. Stat. § 102.23 which provides for judicial review. The section pertinent to the issue in this case is § 102.23(1)(b):
*278 (b) In such an action a complaint shall be served with an authenticated copy of the summons. The complaint need not be verified, but shall state the grounds upon which a review is sought. Service upon a commissioner or agent authorized by the commission to accept service constitutes complete service on all parties, but there shall be left with the person so served as many copies of the summons and complaint as there are defendants, and the commission shall mail one copy to each other defendant.
¶ 12. The plain language of Wis. Stat. § 102.16(2m)(e) directs parties to rely on Wis. Stat. § 102.23 to appeal a Department necessity of treatment order to the circuit court. The plain language of § 102.23 requires that service be achieved by serving a "commissioner" with enough copies of the summons and complaint as there are defendants.
¶ 13. Although the statutes are plain on their face, statutes may be rendered ambiguous by their interaction with other statutes.
State v. White,
¶ 14. McDonough relies on the plain language of Wis. Stat. § 102.23 to argue the statute allows that *279 service in an appeal of a Department order can be achieved by serving the Commission with enough copies of the summons and complaint as there are defendants. The Department argues that Wis. Stat. §§ 102.16(2m)(e) and 102.23(1)(b) must be read in pari materia. That is, because the statutes relate to the same subject matter, they should be read together. When read together, the Department asserts, the word "department" should be read into § 102.23 where "commission" is used.
¶ 15. We agree, to some extent, with both parties. We hold that, given the ambiguity presented by the interaction of Wis. Stat. §§ 102.16(2m)(e) and 102.23(1)(b), service for appeals under § 102.16(2m)(e) can be achieved by timely serving either the Department or the Commission with enough copies of the summons and complaint as there are defendants.
See Wisconsin Finance v. Garlock,
¶ 16. We agree with the Department that when two statutes deal with the same subject matter, we read them
in pari materia. Gottfried, Inc. v. Dept. of Revenue,
¶ 17. The purpose of the Workers Compensation Act, enacted as Wis. Stat. ch. 102, "is to give prompt relief to injured employees who are entitled to compensation."
Cruz v. ILHR
Department,
¶ 18. The purposes of both Wis. Stat. §§ 102.16(2m)(e) and 102.23 can be achieved if they are read
in pari materia.
Reading "department" in place of "commission" throughout § 102.23 when a party is appealing a Department order under § 102.16(2m)(e) allows parties to promptly achieve judicial review and gives both statutes their full force and effect.
See Kaiser v. City of Mauston,
¶ 19. Our reading of the statutes in this way is also supported by common sense.
See State v. Clausen,
¶ 20. Reading Wis. Stat. §§ 102.16(2m)(e) and 102.23 in pari materia and relying on common sense, we conclude that a reasonable interpretation of the statutes is that reading "department" where § 102.23 says "commission" is appropriate for appeals from Department orders under § 102.16(2m). Accordingly, we hold that, given the ambiguity presented by the interaction of §§ 102.16(2m)(e) and 102.23(1)(b), service for appeals under § 102.16(2m)(e) can be achieved by timely serving the Department with enough copies of the summons and complaint as there are defendants.
¶ 21. Another equally reasonable interpretation of the two statutes as they interact is found by relying on the language of the statutes. In the present case, Wis. Stat. § 102.23 specifically requires the plaintiff to achieve service by serving a "commissioner" with enough copies of the summons and complaint as there are defendants. § 102.23(l)(b). There is nothing corn-
*282
plex or confusing about § 102.23 — the statute "plainly requires service on the commission."
Gomez v. LIRC,
¶ 22. When an ambiguity exists regarding the specific party to be served, procedural statutes must be construed liberally to achieve determination of the merits of the controversy, if such construction is possible. De
pt. of Transportation v. Peterson,
No. 97-2718, op. at 6 (S. Ct. June 8, 1999). Where a procedural statute is ambiguous, whether that ambiguity is created by a statute itself or the interaction of two or more statutes, "the ambiguity is to be resolved in favor of the person appealing the [agency's] award of damages."
Id.
at 7. Where the petitioner has complied with the language of § 102.23(1)(b) regarding the procedure for service, it would be extraordinarily harsh to cut off petitioners' right to a review of the Department's order.
See id.
(citing
Trojan v. Board of Regents,
¶ 23. As directed by the language of Wis. Stat. §§ 102.16(2m)(e) and 102.23, and the Department's order, McDonough complied with § 102.23 to appeal the Department's order under § 102.16(2m). Within 30 days after the Department issued its order, McDonough served four copies of a summons and complaint, one for each defendant, upon a commissioner. Faced with the ambiguity created by the interaction of the two statutes, but in accord with the language of the statutes, it was reasonable and logical for McDonough to achieve service by serving a commissioner with *283 enough copies of the summons and complaint as there are defendants.
¶ 24. Relying on the language of Wis. Stat. §§ 102.16(2m)(e) and 102.23(l)(b), we hold that, given the ambiguity presented by the interaction of the statutes, service for appeals under § 102.16(2m)(e) can be achieved by timely serving the Commission with enough copies of the summons and complaint as there are defendants. Accordingly, McDonough achieved service by timely serving a commissioner with enough copies of the summons and complaint as there are defendants.
¶ 25. If the legislature or Department disagree with our interpretation of the interaction between Wis. Stat. §§ 102.16(2m)(e) and 102.23(l)(b), both are free to clarify the procedures an aggrieved party must follow to appeal a necessity of treatment order made by the Department.
See Peterson,
slip op. at 7. The legislature, of course, is free to amend either or both statutes. The Department also can take steps to eliminate confusion.

Litigants should not be kept guessing as to which governmental entity to name and serve in proceedings for judicial review.
Sunnyview Village v. Administration Dept.,
¶ 26. In sum, we hold that, given the ambiguity presented by the interaction between the two statutes at issue, service for appeals from Department orders under Wis. Stat. § 102.16(2m)(e) can be achieved by timely serving either the Department or the Commission with enough copies of the summons and complaint as there are defendants. Because McDonough served enough copies of the summons and complaint with a commissioner as there are defendants, we conclude that he achieved service. Accordingly, we reverse the decision of the court of appeals and remand the cause to the circuit court for proceedings on the merits. 4
By the Court. — The decision of the court of appeals is reversed and the cause is remanded to the circuit court for proceedings on the merits.

McDonough v. Department of Workforce Development, No. 97-3711-FT, unpublished slip op. at 4 (Wis. Ct. App. Aug. 20, 1998).
Because we have determined that service for appeals from Department orders under Wis. Stat. § 102.16(2m)(e) can be achieved by timely serving either the Department or Commission with enough copies of the summons and complaint as there are defendants, and therefore, are remanding for judicial determination on the merits, we do not address other issues raised by the parties.
