Coded Landing

[senegence487]

I’m a US citizen and have visited the UK 2-3 times a year for the last 6 years to visit my now husband. After a holiday in Europe, I had a layover in London. When landing, I told the IO this, and he commented on my visits and gave me a coded landing with “forty eight hours” noted.

I fell ill from a virus contracted on vacation, and had to remain in the UK for 3 weeks after my initial flight. I have a doctors note and spoke to Voluntary Departures while in the UK previously.

Will I be refused entry automatically on my next visit? Or should I just come prepared with all of my documentation?
