If the provider documented that the facet syndrome spanned both the lower thoracic region and upper lumbar region, i.e. T11 - L2, the diagnosis could be reported as M53.85. I would only code the M53.80 code if the provider documented facet syndrome without indication of any spinal region.
Wasps are actually beneficial insects for humans and the environment. They are one of the major natural scavengers, and they eat insects such as flies and caterpillars that are often considered pests to humans.
The stinger is barbed, so once it pierces the skin, it cannot be retracted. Wasps and other bees do not have a barbed stinger so they are capable of multiple stings. But I think the question here is more on the capability of a wasp or bee being able to deliver a sting after it has died.
