Klingon insurance programs do class that as a complication of battle and therefore an honourable death.
Unfortunately for the Klingons the Ferengi insurance underwriters class most deaths as non accidental and therefore don't pay out, they realized most Klingons are happy enough to be told it was honourable even if they receive no compensation.
Klingon insurance also has Act of God's clauses, but because they killed their gods they never pay out.
Long story short, never get Klingon healthcare or give them powers of attorney, they're not a financially minded people.
