It's closer to how some dialects of English will say "Do you want to come with?" and consider that a complete sentence.
FWIW, there is no harm in the correction. "codes" is correct in Indian English, Indian English is a variant just as much as Australian English is, and people abroad will auto-bucket you as less intelligent than someone speaking more common forms. So it is still a smart action to switch yourself to the more common forms.
