Medicare patient was admitted to the hospital for observation on 2/1. Stayed in hospital under observation until 2/3 when she was admitted as inpatient. Final discharge was 2/11.
I billed as follows:
2/1 99220 pos=22 (outpatient)
2/2 99219 pos=22 (outpatient)
2/3 99213 pos=21 (inpatient)
2/1 & 2/3 paid. 2/2 is denied as an invalid procedure code or modifier. I don't see any CPT's in the book for subsequent hospital observation. How should the second day of observation be coded?
Thanks in advance.
