Actually, 428.0 is just the unspecified CHF code. To be more precise you would want to know if it is systolic or diastolic and from there you would code it with the 4th digit "3" as "acute on chronic". (example: 428.23 systolic heart failure/acute on chronic). There isn't an actual "exacerbation" code for CHF that I am aware of.
