If Medical Revenue Service called, texted or sent you a letter

Medical Data Systems, Inc., doing business as Medical Revenue Service (“MDS”), is a real Vero Beach, Florida company that collects hospital and medical bills for hospitals and health systems. If you were contacted by phone from 888-773-2255, 877-521-6773, or 772-770-2255, or by text from short code 60204, those numbers match contact information MDS publishes, but that alone does not prove a particular call or text is genuine, because caller ID can be faked. If you are unsure, hang up and call back on a number from meddatsys.com, or call the billing office number printed on your own hospital bill, rather than a number given to you during the contact.

The company's website is meddatsys.com, and its payment portal at payment.meddatsys.com asks for the EID, which the portal describes as a 10-character code printed on the letter, text or email you received, plus the last four digits of your Social Security number to pay without creating an account — a payment page asking for something different is worth double-checking before you enter anything.

Before paying anything, a few practical steps:

• Ask MDS (or the hospital) for an itemized bill and the name of the hospital or medical provider the balance is for.
• Check the bill against your insurance company's Explanation of Benefits (EOB) to see what your plan already paid and what you actually owe.
• Ask the hospital directly about financial assistance or charity care — nonprofit hospitals subject to Internal Revenue Code §501(r) must maintain a financial-assistance policy, although eligibility and procedures vary.
• If you want to dispute the debt, put it in writing. A timely written dispute matters: under the FDCPA, a collector that receives one generally must stop collecting the disputed amount until it sends you verification. If the federal Fair Debt Collection Practices Act applies, 15 U.S.C. §1692g generally gives you 30 days after you receive the collector's validation notice to tell the collector in writing that the debt, or part of it, is disputed and to request verification; keep proof that you sent it. MDS also says it performs early-stage billing as some hospitals' “Extended Business Office.” Whether the FDCPA applies to a particular letter or call can depend on the role MDS was acting in; the label or billing stage alone does not answer that question.
• If you pay or settle a balance, get a written $0-balance or paid-in-full letter and keep it.
• Check your credit reports at annualcreditreport.com to see whether the account was reported, and dispute anything inaccurate with the credit bureau.

Medical collections and your credit report

Equifax, Experian, and TransUnion changed how medical debt appears on credit reports in two steps. As of July 1, 2022, medical collection debt paid in full is no longer included on credit reports, and the wait before an unpaid medical collection can appear was extended from six months to one year. In April 2023, medical collections with an initial reported balance under $500 were also removed. An unpaid medical collection of $500 or more can still appear after the one-year wait.

Separately, a Consumer Financial Protection Bureau rule finalized in January 2025 that would have banned medical debt from credit reports entirely was vacated by a federal court in the Eastern District of Texas on July 11, 2025, so that particular federal ban is not currently in effect. Some states have their own, separate protections for medical debt on credit reports; check with your state attorney general's office for what applies where you live.

MDS's own website does not clearly say whether, or when, it reports collection accounts to the credit bureaus. Its privacy notice does say it may disclose information about you to third parties “such as credit bureaus.” The company does not publish a separate mailing address or hours for credit-reporting disputes.

One example from the Better Business Bureau's file, filed August 29, 2026, shows why it is worth following up after you pay: a consumer reported paying a settlement on August 14, 2026, and receiving a $0-balance letter from MDS dated August 18, 2026, but found that a credit-bureau dispute over the account had not been updated to reflect it. That is one consumer's account of their own experience, not a verified finding about MDS's practices generally.

Complaint volume is concentrated in Georgia

Georgia accounts for a large share of the complaint record against Medical Data Systems. Of the 3,008 complaints in the CFPB's public database, 1,154 — well over a third — were filed by consumers in Georgia, far more than any other state (North Carolina is next, at 353). Court filings show a similar pattern: of the 120 most recent federal dockets naming the company, 31 were filed in the Northern District of Georgia, more than any other single federal court.

Public records reviewed for this page do not identify which Georgia hospitals or health systems use MDS as a billing or collection vendor. If you received a letter or call from MDS about a Georgia medical bill, the letter itself should name the hospital or provider the balance is for — that is the fastest way to confirm who you actually owe.

Company background

Medical Data Systems, Inc. does business as Medical Revenue Service. The company's own site says it was “Founded in 1985” and was “an early pioneer of Secondary Collections,” describing itself as trusted by three of the ten largest health systems in the country by bed count. A 2015 company press release says the firm was founded by G. David Miller and his wife Amy in Sebring, Florida, and that Gary Ball joined as a partner in 1997, becoming Chairman and CFO, around the time the office moved to Vero Beach. The Florida registry lists Rick Masterson as President and Gary Ball and Giles D. Miller as Co-Chairmen; the Better Business Bureau's file also lists Clifford Lahman as CFO and Kesha Reaves as Manager.

MDS describes its services as: SWIFT text-and-pay; an “Extended Business Office” handling self-pay and residual patient balances plus insurance follow-up before an account becomes bad debt; primary and secondary collections; system-conversion assistance; and “Accelerated Management Solutions.” The company's own site says it combines “artificial intelligence with layers of robotic process automation” and that it “maintains the SOC2 Type II Certification” — both are the company's own claims about itself, not independently verified for this page. The company's home page names client testimonials from St. Luke's University Health Network, BJC, and Childress Regional Medical Center.

MDS's Nevada-licenses page states NMLS numbers #934576 and #1912070, and a Nevada compliance-manager number, CM12950 — these are the company's own stated license numbers. The BBB file lists a Florida Office of Financial Regulation license number, CCA0900156; check its current status directly with the Florida OFR. A separate consumer notice on the company's site says that for New York City (the five boroughs), MDS provides Spanish-speaking telephone agents and Spanish translations of its letters.

Florida's corporate registry (Sunbiz) lists Medical Data Systems, Inc. as an active Florida profit corporation, document number K47033, filed November 23, 1988. Its principal and mailing address there is 958 20th Place, 3rd Floor, Vero Beach, FL 32960 (updated January 6, 2026), which matches the company's own contact page. The BBB file still shows an older Vero Beach address, 2001 9th Ave, Suite 312. The company's privacy notice gives a third address, 755 West NASA Boulevard, Melbourne, FL 32901-3009, for written requests to opt out of information sharing.

Similarly named businesses that are not Medical Data Systems

The names “Medical Revenue Service” and “Medical Data Systems” are similar to several unrelated businesses, and it is easy to confuse them:

• A listing on RevDex for “Medical Revenue Services” (plural), with a P.O. Box 5188, Martinsville, VA 24115 address and phone (877) 765-4604, is a different business — not MDS.
• MRS BPO, LLC, a New Jersey collection agency (with its own 2 posts on USAComplaints filed under “Mrs Bpo Llc”), is a separate, unrelated company.
• Med-Data, Inc. (also known as MedData) — a different company reported to have had a publicized data exposure and related class-action litigation — is not the same company as Medical Data Systems, Inc. No comparable data-breach report was found for MDS.
• Other billing companies using “Medical Revenue Services, LLC” or similar names, including the site medicalrevenueservice.com, are separate businesses.

The simplest consistency check is whether the phone number matches 888-773-2255, 877-521-6773, or 772-770-2255, and that any website referenced is meddatsys.com. A match is a useful check, but it does not by itself prove an incoming call or text is genuine; dial the number yourself from meddatsys.com or your hospital bill.

Complaint record: USAComplaints, then CFPB and BBB, reported separately

USAComplaints has no complaints of its own about this company yet. That does not by itself prove or disprove anything about MDS's practices — it simply means no reader has filed a report here naming this company so far.

Separately, the Consumer Financial Protection Bureau's public complaint database lists 3,008 complaints against Medical Data Systems, Inc. between July 13, 2013 and September 25, 2026 — 497 in the last 12 months and 1,040 in the last three years. Most (2,527) are categorized under debt collection, with 471 under the two credit-reporting product categories combined. The most common issues logged are: attempts to collect a debt not owed (1,048), written notification about the debt (618), incorrect information on a credit report (239), threatened negative or legal action (203), false statements or representation (186), and communication tactics (160). By state, complaints came overwhelmingly from Georgia (1,154), followed by North Carolina (353), Texas (238), Florida (192), South Carolina (190), Pennsylvania (135), and Alabama and Nevada (86 each). The company's responses are recorded as closed with explanation on 2,985 complaints, with 23 still in progress; 2,950 were timely and 58 were not. The CFPB notes that complaints in its database are not verified; a complaint shows what a consumer reported, not what happened.

Separately again, the Better Business Bureau's Vero Beach file gives the company an A rating while noting it is not BBB accredited, citing “305 complaint(s) filed against business” as a reason for the rating. BBB shows 305 complaints in the last three years, with 61 closed in the last 12 months, and an average of 1 out of 5 from 19 customer reviews. Of the ten complaints BBB displays in detail, all were filed in 2026 and marked “Answered” — eight billing issues, one product issue, and one service issue.

None of these three figures — USAComplaints' 0, the CFPB's 3,008, or the BBB's 305 — describe the same population of consumers or the same time period, and none are added together here.

Litigation record

Court records show a long history of federal lawsuits naming Medical Data Systems, Inc. or Medical Revenue Service, mostly alleging violations of the federal Fair Debt Collection Practices Act (15 U.S.C. §1692) and occasionally the Fair Credit Reporting Act (15 U.S.C. §1681). In a CourtListener search run on September 27, 2026 for federal cases with “Medical Data Systems” or “Medical Revenue Service” in the case name, among the 120 most recent dockets, filings span February 2018 through September 2026 (earlier dockets go back to at least 2010, plus a 2002 bankruptcy adversary proceeding), and 110 of those 120 are already closed — typically within about three and a half months, and 85 within six months. As with any lawsuit, a filing is an allegation, not a finding, and when an individual case closes, the court record usually does not show whether or on what terms it was resolved. Recent examples include Sullivan v. MDS (D. Kan., filed September 16, 2026), Gresham v. MDS (N.D. Ga., filed July 29, 2026), and Williams v. Medical Revenue Service (N.D. Ga., filed July 10, 2026).

Two older cases resulted in published court decisions, described in the Court Cases section below: Carn v. Medical Data Systems, Inc. (In re Cambron), a 2007 federal district court ruling, and Lait v. Medical Data Systems, Inc., a 2018 Eleventh Circuit appeal.

Searches run for this page on September 27, 2026 found no CFPB, FTC, or state attorney general enforcement action naming Medical Data Systems.

Is Medical Revenue Service (Medical Data Systems, Inc.) Legitimate?

Medical Data Systems, Inc., doing business as Medical Revenue Service, is a real, long-operating company: the Better Business Bureau's file shows a business-started date of November 1988, and the company has appeared as a named party in federal court cases going back at least to the 2000s. Its own site states it has been assisting hospitals with revenue-cycle and receivables work “since 1985” and says, in its own words, “We are licensed all required states” — that licensing claim is the company's own statement, not independently verified for this page.

The public complaint counts are 3,008 in the CFPB database since 2013 and 305 on BBB in the last three years. CFPB complaints are unverified consumer submissions, and the public records do not show how many accounts MDS handles, so a complaint rate cannot be calculated or compared. Searches run for this page on September 27, 2026 found no CFPB, FTC, or state attorney general enforcement action naming the company, and no reported data breach involving MDS itself (as distinct from the unrelated company Med-Data/MedData).

To protect yourself: confirm any contact using the phone numbers and website listed on this page rather than a number given to you during a call or text; ask for an itemized bill naming the hospital or provider; get everything in writing; and use your rights to dispute the debt and request verification before paying.
