Use additional code
Does the "use additional code" instruction mean to code the additional code anywhere below the code with that instruction, or does it mean code the additional code immediately after code with the instruction? For example, for a patient with HTN, heart failure, kidney disease, COPD and atrial fib who is admitted to home care with focus of care on hypertension, COPD and atrial fib, would one code I13.0, I50.9, N18.9, J44.9, and then I48.91, or would you code I13.0, J44.9, I48.91, and then code the I50.9 and N18.9? I've had different opinions on this question. Thanks.
