The first thing to know about billing in Washington is that the metro is three jurisdictions in a trench coat. A practice in Bethesda, Arlington or Alexandria bills patients who live in the District, Maryland and Virginia, and each of those has its own Medicaid managed care arrangement, its own licensing board and its own quirks. A front desk that treats every address as the same state sends claims to the wrong place. The academic names are familiar: Georgetown, George Washington and Howard train physicians, MedStar runs a large share of the hospitals, Children's National anchors pediatrics, and Inova and Kaiser Permanente hold big pieces of the northern and Maryland suburbs.
The commercial book leans toward federal employees and contractors. Federal employee health plans, the regional Blue plan and large employer coverage make up much of it, TRICARE adds military families, and Medicare Advantage is growing in the older close-in suburbs. Medicaid is a real business too, because the District covers many residents through managed care organizations. Patients with good coverage tend to have high deductibles, so patient balances matter as much as payer claims. Credentialing is slow, and a physician who moves between the District and a suburb often finds the plan still has the old address on file.
Independent practices that keep going here tend to be dermatology, orthopedics, physical therapy, behavioral health, pediatrics and concierge-style primary care. The hospital systems keep buying, and the cost of living makes experienced billing staff expensive to hire and easy to lose to a bigger employer. When you look for outside help, build the form around where your patients actually live. Then add which payers you bill most, how many providers you have, what software you use, and how much of your AR is older than ninety days.
