Tentacles of an octopus as well limbs of a lizard are analogous structures.
Analogous structures or organs perform the same function in different organisms that bear no resemblance to each other anatomically. Analogous structures are formed as a result of convergent evolution, i.e. different structures evolving for the similar function and thus having similarity. Tentacles of an octopus as well as limbs of a lizard are used for the similar function, i.e. locomotion in this case.
On the other hand, homologous structures result from divergent evolution. Homologous organs contain a similar basic structure but perform distinct functions in different organisms.
The CPT code that will be reported for moderate sedation is 9914 [4]. This is the government approved CPT code for moderate sedation for patients that are five years old and older and the code is used when the moderate sedation and the other needed procedure is performed by the same health provider for the intraservice period of 15 to 30 minutes.
