DAX Calculate Measure with IF Statement - if-statement

Question

I am trying to count the number of codes {"1V", "2V", "3V"} contained in the [ToStatus] and [FromStatus] column of the' Master Report' table. However, I need only count the code once if it appears in both columns.
I am relatively new to DAX and the below is my attempt at coding same. I would be obliged if any of the gurus out there could be of assistance :)
Psuedo code:
If any of the values {"1V", "2V", "3V"} is in column [ToStatus] and [FromStatus]
Just count [ToStatus] else count [FromStatus] and return the total
Attempt in DAX:
=IF(('Master Report'[ToStatus] IN {"1V", "2V", "3V"} && 'Master Report'[FromStatus] IN {"1V", "2V", "3V"}),
CALCULATE([_PatientCount],
FILTER('Master Report',
'Master Report'[ToStatus] IN {"1V", "2V", "3V"}),
CALCULATE([_PatientCount],
FILTER('Master Report',
'Master Report'[FromStatus] IN {"1V", "2V", "3V"} ||
'Master Report'[ToStatus] IN {"1V", "2V", "3V"})
)
Sample Data:
ID Code FromStatus ToStatus
145320150978 3V 2V
145320150978 3V 2V
145320210617 RH 3V
145320210617 2V ZO
145320210628 3C 2V
145320210628 2V 5L
145320211246 3V 5S
Update: Also I forgot to mention that the purpose of the _PatientCode measure is to count DISTINCT patient codes!
Update: I have now resolved this by doing it in MySQL instead of DAX and then just counting the 1 values in DAX.
Thanks in advance,
Conor.

Answer 1

Some brackets were missing, others were superfluous:
MyMeasure =
IF (
'Master Report'[ToStatus] IN { "1V", "2V", "3V" }
&& 'Master Report'[FromStatus] IN { "1V", "2V", "3V" },
CALCULATE (
[_PatientCount],
FILTER (
'Master Report',
'Master Report'[ToStatus] IN { "1V", "2V", "3V" } )
),
CALCULATE (
[_PatientCount],
FILTER (
'Master Report',
'Master Report'[FromStatus] IN { "1V", "2V", "3V" }
|| 'Master Report'[ToStatus] IN { "1V", "2V", "3V" }
)
)
)

Answer 2

Resolved from MySQL side with code below:
(CASE
WHEN ToStatus LIKE '%V' OR FromStatus LIKE '%V' THEN 1
ELSE 0
END) as V_Count
