Sure it is. If 5% of asymptomatic cases require care that costs $200k, you come to $10k a person. This is entirely plausible in the US, particularly if you are amortizing the cost over the lifetime of the patient.
Can you cite any paper that suggests serious complications for asymptomatic patients is anywhere even remotely close to 5%? All I've seen is a handful of rare anecdotes, nothing to suggest it's a remotely likely outcome.
You're looking at actuarial estimates. Overestimating unknown-unknowns is more pragmatic than underestimating them. No, the article doesn't show how that particular sausage is made; we're all out here guessing.
