Physician Ranking: health care transparency or scam?
Written by Patricia King, JD   
Over the last year, the once-esoteric topics of physician ranking and “high performance networks” have been fighting words for physicians, health insurers and the New York Attorney General.  On the one hand, advocates of consumer-driven healthcare hope that when consumers have solid data comparing health care providers’ quality of care and cost effectiveness, they will make sound choices that will bring U.S. health care costs down.  On the other hand, physician ranking systems built on inaccurate and incomplete data offer no benefit to consumers, and unfairly penalize physicians who are inappropriately placed in a lower tier.


Physician Ranking:  Necessary tool for health care transparency, or scam on doctors and the public?

Medical society litigation

The first lawsuit challenging insurance company physician ranking plans was filed in November 2006 by the Washington State Medical Association against Regence BlueShield. Regence settled the suit in August 2007, agreeing to hold off on physician tiering programs until a new program can be developed with physician input.  While the Washington case was being settled, a similar lawsuit was being filed in Connecticut.  The Fairfield County Medical Society sued United Healthcare and Cigna, challenging a system in which certain physicians were designated as “elite” and patients were charged lower copays to see the favored physicians.  The Connecticut doctors claimed that the ranking system, derived from claims data, bore no relationship to quality of care and simply reflected the insurers’ desire to save money.  This case is still pending.    

Most recently, the Massachusetts Medical Society sued the Commonwealth’s Group Insurance Commission (GIC), Tufts Health Plan and Unicare for defamation and fraud in May 2008, claiming that the system for assigning physicians to one of three tiers based on quality and cost efficiency was arbitrary.   Under the GIC’s Clinical Performance Initiative (CPI), the plans measure “quality” according to the physician’s compliance with clinical guidelines.  In challenging the fairness of this measure, the complaint alleges that “the clinical measures used are just a small fraction of the standards of quality care in a particular specialty, but are used because they purportedly lend themselves to evaluation through claims data.” Ref. 1  The complaint further states that there is no effective appeal process for physicians who believe their ranking is inaccurate.  The tiering report received by physicians identified the percentile ranks, number of quality measures and conditions, the “Top 5 Clinical Measures” for that physician, and charts comparing the physician to his/her peers.  The underlying data was de-identified, so there was no way for the physician to link it to patient records to challenge the quality score.  The complaint gives a number of examples of problems with the quality data, such as the following reported by a cardiologist:

Of 125 quality measures, 33 involved Tufts patients, for whom he received credit for performing the appropriate testing or therapy in 29 cases.  The MMS member reviewed his own files and determined which Tufts patients the claims data likely referred to.  Upon further review, he noted that with respect to 3 of the 4 missed opportunities, he had never seen the patient, but had merely read echocardiograms, and the care was inappropriately attributed to him.  With respect to the fourth patient, the missed measure involved care being managed by the patient’s primary care physician. Ref. 2

The complaint also gives examples of specialists whose cost-efficiency score suffered because of the acuity level of their patients (such as a medical director of a multiple sclerosis center, and a glaucoma specialist whose practice required more expensive testing than typical for ophthalmologists generally). 

An especially interesting aspect of the Massachusetts lawsuit is that the Medical Society named not only health plans, but also the GIC, as defendants.  The GIC is a state agency that established the requirement for physician tiers.  The GIC’s website states that it endorsed the Consumer-Patient Disclosure Project’s “Patient Charter” (described below).  Its Executive Director notes the Medical Society’s lawsuit, and comments that “It is regrettable that the MMS has chosen to be confrontational about the CPI initiative rather than continuing to work with us to bring quality and efficiency information to patients and providers alike.” Ref.3

New York’s Attorney General joins the fray

In July 2007, the New York Attorney General sent similar letters to CIGNA Healthcare, Inc., Aetna Health, Inc., and UnitedHealthCare, Inc. expressing concern that their physician ranking programs could confuse or deceive consumers.  The Attorney General’s office listed three main concerns (excerpted from the UnitedHealthCare letter):

  • Consumers may be steered to doctors based on faulty data and criteria.
  • Consumers may be encouraged to choose doctors because they are cheap rather than because they are good.  This could undermine the integrity of the doctor-patient relationship.
  • UnitedHealthcare’s profit motive may affect the accuracy of its quality rankings because high-quality doctors may cost United- Healthcare more money.  This is a conflict of interest. Ref. 4    

The Attorney General’s shot across the bow was extremely effective.  By October 29, CIGNA had entered into an agreement resolving these concerns, followed quickly by Aetna, UnitedHealthCare, Empire Blue Cross and many others.  The insurers agreed to accept the Attorney General’s Doctor Ranking Model Code, which was developed in collaboration with the American Medical Association, the Medical Society of the State of New York, and consumer groups including the Consumers Union.  The Model Code requires insurers to:

  • Not base ratings solely on cost, and identify the degree to which ratings are based on cost;
  •  Use established national standards to measure quality and cost efficiency, including measures endorsed by the National Quality Forum (NQF);
  • Use measures to improve the accuracy of physician comparisons, such as risk adjustment and valid sampling;
  • Disclose to consumers how doctors are ranked, and establish a consumer complaint process;
  • Disclose to physicians how rankings are designed, and provide a process to appeal disputed ratings; and
  • Retain a Ratings Examiner to report to the Attorney General every six months on the insurer’s compliance with the Model Code.  The Ratings Examiner must be a national standard setting organization, such as the National Committee on Quality Assurance (NCQA).

The beginnings of a consensus?

The same time that insurers were signing agreements with the New York Attorney General, a coalition of consumer, labor and employer organizations were putting the finishing touches on a similar project.  Known as the Consumer-Purchaser Disclosure Project, a collaboration of the AARP, the AFL-CIO, the Leapfrog Group, the National Business Coalition on Health and others endorsed a set of principles known as the Patient Charter for Physician Performance Measurement, Reporting and Tiering Programs.  The Patient Charter calls for:

(i)  reliance on NQF measures as a first choice, and then measures approved by national accrediting bodies such as NCQA and the Joint Commission;

(ii) provider and consumer input on supplemental measures, if any are to be used;

(iii) a transparent provider rating method; and

(iv) coordinated data collection by independent third parties.    

With New York’s Model Code and the Patient Charter, there are now carefully-drawn guidelines for constructing a physician ranking program.  Programs that do not adhere to the guidelines, such as tiering programs based solely on cost, will be vulnerable to medical society challenges.  On the other hand, programs that can show they meet most elements of the Model Code or the Patient Charter will have a strong defense against claims that their methodology is arbitrary and just a façade for saving medical claims expense.
