call private sub from module

Is it possible to call a Private Sub from another Module?

Sub GroupPreference_10Year()
    Call ColumnSort_10Year
    Filter = 10
    Target.Column = 18
    call private sub Worksheet_BeforeDoubleClick
End Sub

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)

Dim i               As Long
Dim LastRow         As Long
Dim MaturityValue   As String
Dim Color           As Long
