I'd like to know how other facilities code the WCC for the first year if they are coming in the first month for a weight check? Our providers only want to use the 99391 at 2 weeks, 4 weeks, and 2-4-6-9- and 12 mos. Anything in between they don't want to use the 99391. So for weight checks, jaundice checks, with all the other elements of a wellness check with no real diagnosis we are using Z01.89 encounter for other specified special examinations. And use 99212-99215 CPT's. I can't find any guidance to how often they can use the 99391 the first year. Anyone know the answer to that question?
