This is the SMO answer in PowerShell:

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | out-null

$srv = New-Object "Microsoft.SqlServer.Management.Smo.Server" "MyServer\MyInstance"
$db = $srv.Databases["MyDatabase"];
$proc = $db.StoredProcedures["MyStoredProcedure"]

foreach($parameter in $proc.Parameters) {
  if ($parameter.DefaultValue){
     Write-Host "$proc ,  $parameter , $($parameter.DefaultValue)"
  }
  else{
     Write-Host "$proc ,  $parameter , No Default Value"
  }
 }
