In both the CR and the SR individuals choose their insurer as well as the provider within the insurer’s network. Enrollment mechanisms between the two systems, however, are quite distinct. While anyone is free to enroll in the CR, it is mandatory for formal sector workers and self-employed workers who earn one minimum salary per month. The CR enrolled 13,335,932 persons in 2001 and 17,234,265 persons in 2008.

In both the CR and the SR individuals choose their insurer as well as the provider within the insurer’s network. Enrollment mechanisms between the two systems, however, are quite distinct. While anyone is free to enroll in the CR, it is mandatory for formal sector workers and self-employed workers who earn one minimum salary per month. The CR enrolled 13,335,932 persons in 2001 and 17,234,265 persons in 2008.

Between 1993, when the reform was passed, and 2002, there arose the need to implement monitoring and supervision mechanisms to enforce the enrollment of self-employed workers in the CR. This has largely been achieved through two distinct methods. First, law 797 of 2003 linked pension and health insurance contributions. This affected enrollee evasion, as individuals wishing to have a pension must also have health insurance. It also affected contribution evasion, since the income level used to calculate pension contributions is also used to calculate CR contributions. Second, decree 1703 of 2002 instituted sanctions on employers if they did not ensure that self-employed workers (e.g. consultants) participated in the CR. Finally, between 2006and 2007 the Integrated Payroll Contributions Settlement system was instituted, obliging all companies and the self-employed to settle their social security payments through electronic fund transfers.

While the expansion of the SR was taking place, a unique and innovative enrollment qualification criteria was used designed to give priority to targeted groups based on income level and degree of vulnerability/likely need for care, while taking into consideration the available funds. Priority was given to special populations such as orphans and the elderly, regardless of SISBEN score, which is the proxy-means test used to identify the most vulnerable members of a community. Preference was then assigned to the poor who were either pregnant, under the age of 5, displaced by violence, or disabled. The rest of the population was ordered by SISBEN score, with a score of 1 representing the most destitute and a score of 5 representing the least destitute. Once the ranked list was published, individuals signed up with an EPSS of their choice. If an individual did not sign up, he or she had to wait until the next round of affiliations to do so. Enrollment of those who were eligible was ongoing as additional funds become available. Also, after all level 1 and 2 individuals were covered, municipalities that had resources left over could begin to cover level 3 individuals. This process was slightly altered by Accord number 415 of 2009, which states that the non-affiliated, eligible population can sign up with the SR at any point during the year. In 2002 the SR enrolled 11,444,003 persons. By 2009, this number had risen to 23,804,788.

An important issue is the monitoring of fraud within the SR. Starting in 2000, the government began monitoring and updating the subsidized scheme databases. This led to the expulsion of many fraudulent enrollees. By 2005, a complete database of SR enrollees had been set up and included their names, identification numbers, and the name of their EPSS. This database was completed in 2009.

Beginning in 2004, there was an expansion of partial subsidies to SISBEN level 3 individuals. The UPC for this plan equals approximately 42% of the CR UPC. While this plan expands coverage to those who remain uninsured, it offers a smaller benefits package. As of March 2009 there are 1,115,789 individuals covered by partial subsidies.

Lack of automatic mobility between the SR and CR upon a change in labor standing among the poor is thought to be a disincentive for Colombians to move into formal employment. The fear existed primarily among subsidized regime enrollees who would not be able to easily rejoin the SR if they lost their formal sector employment. To deal with this concern, in 2005 the government stated that a person can be reinstated into the SR within the year in case of subsequent eligibility changes. Furthermore, at the end of the year the process of re-enrolling in the SR will be quicker and easier. This change should lead to expansions in the formal workforce and higher levels of CR enrollment as more people are willing to leave the SR.

Population coverage has increased significantly since the 1993 reform, with a substantial part of the growth taking place after 2002. In 1990, 15.7% of the population had health insurance coverage. By 2008 the percentage of those covered had risen to 89.36%. This is a 570% increase in coverage over an 18 year span. The populations that were most affected by the reform were the bottom 2 income quintiles. Figure II shows that coverage for quintile 1 increased by 540% while quintile 2 increased by 250% between 1992 and 2003. Figure 2 also shows that there was a drop in coverage between 1997 and 2000, with an eventual recovery in 2003. This effect was primarily caused by a severe macroeconomic recession between 1998 and 2000. The recession not only reduced formal employment, affecting enrollment in the CR as well as the solidarity contribution to the SR, but it also reduced general tax transfers to the SR. With the recession ended and renewed political support for health coverage, the growth trend continued its upward movement.

Chile: National Health Fund (FONASA)

Enrollment into FONASA or ISAPREs tends to be tied to income, with lower income individuals joining FONASA and higher income individuals enrolling in an ISAPRE. In 2003, the mean income of ISAPRE members was four times higher than that of FONASA members. Formal sector workers must enroll by allocating 7% of their monthly income or pension (2,000USD monthly maximum) to healthcare. Those who do not work in the formal sector have the option to enroll by allocating 7% of their monthly income, but are not required to do so. These groups can enroll with either FONASA or an ISAPRE of their choice. The indigent and the unemployed are entitled to free coverage by FONASA.

These groups can enroll with either FONASA or an ISAPRE of their choice. The indigent and the unemployed are entitled to free coverage by FONASA.

FONASA divides its beneficiary population into four categories based on income. Category A is composed of the indigent, category B is composed of the very low income population, category C is composed of the lower-middle income population, and category D is composed of the higher-middle income population. Copayment rates are based on these categories.

In 2005, FONASA enrollees numbered 11,329,481, about 70% of the population. ISAPRE enrollees accounted for 2,660,338 during the same year, equaling 17% of the population. In 2006 there were 15 ISAPREs, but over two thirds of members belonged to the three largest: Banmedica, Consalud, and ING Salud. Open ISAPREs are available to the population at large, while closed ISAPREs are only available to particular groups of individuals such as professional associations.

BNHI provides each participant in the program with a smart card that contains their basic medical data. They can use this card at any clinic or hospital in the country, with a small co-pay. The smart card is a valuable tool for maintaining data on patients, and reducing insurance fraud, overcharges, and duplication of medical services.

Health insurance is obtained either through private insurers or the National Health Insurance Scheme (NHIS). About 5 million people are enrolled in the 3 NHIS Programs, which represents just about 3% of the population. In the Formal Sector Program, employees in the formal sector who pay premiums are covered, in addition to their spouse and up to 4 dependants. Companies that employ more than 10 workers are responsible for enrollment of their employees.

Companies that employ more than 10 workers are responsible for enrollment of their employees.

In the Informal Sector Program, the self-employed and individuals living in rural communities enroll themselves. The self-employed must join with at least 500 other members who are occupation based (ie: taxi drivers) to qualify. Rural dwellers have a similar modus operandi, but participants need to belong to the same community rather than the same occupational group. These Social Health Insurance Schemes are self-governed, with elections held to determine who will represent the community. In order to stay enrolled, members are expected to make a monthly contribution actuarially determined based on the benefits package of their choice. Participants requiring specialist or longer treatment would need to pay for the balance from what they are entitled from the common pool. These schemes are expected to cover more than 60% of the rural and self-employed population, though due to poor data collection, the exact population enrolled is difficult to determine.

The enrollment levels in private insurance is uncertain, but based on submissions from private insurers to NHIS, less than 1 million people are privately insured.

The NHIS utilizes 61 Health Maintenance Organizations (HMOs) as health managers for paying healthcare providers, quality assurance, and registration of enrollees and sensitization of participants as part of improving transparency of the system. HMOs contract with the NHIS to manage the enrollment of individuals in health insurance schemes; to collect their payments; pay the healthcare providers; and to provide basic quality management of the health insurance scheme that covers formal employees.

Enrollment in the SP takes place on a per-family basis. A family is composed of the father and/or mother, children and adopted children younger than eighteen or minors younger than eighteen who are dependents and live in the same household, those older than sixty-four years of age who live in the same household, single student children up to age twenty-five, and disabled children. Upon enrollment, families receive a pamphlet with their rights and duties that outlines the health interventions and services to which they are entitled.

Enrollment in the SP takes place on a per-family basis. A family is composed of the father and/or mother, children and adopted children younger than eighteen or minors younger than eighteen who are dependents and live in the same household, those older than sixty-four years of age who live in the same household, single student children up to age twenty-five, and disabled children. Upon enrollment, families receive a pamphlet with their rights and duties that outlines the health interventions and services to which they are entitled. The SP was intended to be rolled out at the health center level. Regions were permitted to enroll individuals only if they had sufficient facilities and human resources to provide adequate care under the program. Enrollment took place at the municipal level, which meant that many municipalities without adequate facilities were not initially able to accommodate large-scale enrollment. State ministries of health are responsible for promotion of the SP program. Voluntary affiliation takes place on a quarterly basis, but enrollees must wait until the following trimester to begin receiving services. Due to the voluntary nature of the program, enrollees must choose to re-enroll annually.

At the start of the program, the primary strategies for enrollment focused on large-scale affiliation campaigns for vulnerable families. Strategies that have been used to aid in the enrollment and re-enrollment process have included the following: coordinating enrollment activities with other programs targeted to poor populations; promoting enrollment in public gathering places like markets and health clinics; communicating with state and local governments to help identify priority populations; collaborating with local governments to speed the processing of official documentation; re-enrollment invitations through mass-mailings to current enrollees; using mass-marketing campaigns to motivate re-enrollment; and launching special brigades for special enrollment campaigns in localities with low levels of enrollment or re-enrollment. However, due to the fact that there were annual quotas on the number of new enrollees, certain states limited the size of their communication campaigns.

During the first years of the SP targeted populations were given priority affiliation. These included those living in rural regions, those who belonged to poverty alleviating programs such as Oportunidades, and indigenous populations. As of 2009, special targeted populations included newborns and pregnant women. Moreover, the last few years have seen the growth of unemployment leading many families to lose their rights to public services such as IMSS or ISSSTE, which has led to an expansion of the enrollment goals for SP beyond what had previously been established.

During the two years of the pilot program between 2001 and 2003, 614,000 families were affiliated. By the end of 2006, this number had increased to 4 million families. In terms of percentages, in 2005 the SPSS covered approximately 14% of the previously uninsured population. By 2009, this number had reached in excess of 90% of the uninsured.
