A sponsored article from Healthcare Dive, written by Jay Sivasailam of Data Axle, argues that health plans often confuse their service area with their actual market. The service-area map defines where a plan is licensed and where its network sits, but it does not show where an employer's workers live or which providers they choose. That distinction matters because members who cannot conveniently reach care are more likely to leave, and retention typically costs less than acquisition.
The article recommends reading three maps together: the service-area map, a workforce map showing where employees commute from, and a care map showing where members seek treatment. Where those maps overlap is the real market; where they diverge are gaps in network reach or product fit. The cost of getting this wrong is significant, the piece notes, citing KFF's 2025 Employer Health Benefits Survey: employer coverage is the largest source of health coverage, with 154 million people under 65 covered, and family coverage averaging $26,993 per year, of which workers pay $6,850.
For regional or mid-market plans, a single bad market bet can move the entire book, unlike national plans that can absorb mistakes. The article suggests four questions before committing to a market: whether the boundary is based on behavior or contract structure, where the employer and workforce actually live, whether the network reaches members where they seek care, and what competitors require to win. The bottom line, according to the author, is that a map matching the market leads to sharper growth decisions.
