Optional columns offer case mix opportunities.

If you're still getting used to M0246 or if you're new to home health coding, this step-by-step guide will help you navigate the OASIS diagnosis code reporting process.

Column 1: Enter the narrative description of the diagnosis.

Column 2: Enter the ICD-9-CM code for the diagnosis and rate the severity of the condition listed in Column 1 as follows:

2 -- Symptoms controlled with difficulty, affecting daily functioning; patient needs ongoing monitoring

3 -- Symptoms poorly controlled; patient needs frequent adjustment in treatment and dose monitoring

4 -- Symptoms poorly controlled; history of re-hospitalizations

Column 3: (Optional) If a V code reported in Column 2 replaces a case mix diagnosis, list the description and ICD-9-CM code of the appropriate case mix diagnosis in the same row in Column 3. Otherwise, leave Column 3 blank in that row.

Column 4: (Optional): If a V code in Column 2 replaces a case mix diagnosis that requires multiple diagnosis codes under ICD-9-CM coding guidelines, enter the diagnosis etiology/underlying diagnosis and ICD-9-CM code in the same row in Column 3. Also list the case mix manifestation diagnosis code and ICD-9-CM code in the same row in Column 4. Otherwise, leave Column 4 blank.
