Bismuth subsalicylate atc code?

What is the ATC code for bismuth subsalicylate?

Bismuth subsalicylate’s ATC code is A03XA.

Why does the ATC code sometimes look different across sources?

ATC classification can vary depending on whether a product is listed as a single active ingredient or a specific combination formulation. If you tell me the exact product name (brand) or whether it’s bismuth subsalicylate alone vs. combined with other ingredients, I can narrow it to the matching ATC entry.
