How to use this page
Everything the published sources say about one code, on one page.
- Read the Excludes1 block first — it is the one that stops you coding this at all alongside another code.
- Excludes2, Code first, Use additional and Includes follow. A note inherited from a parent category is labelled with the category it came from, so you can see why it applies.
- Official Guidelines sit below. "Guidelines naming this code" cite the code or a range containing it; "Chapter guidance" is the general guidance for its chapter and is the weaker signal.
- Guideline text is quoted verbatim with its section number and page, so you can check it against the published document.
- Risk-model chips show which published CMS models map this code.
What this page does not do
- Guidance is quoted, never paraphrased — a paraphrase of a coding rule is a different rule.
- Medication candidates, where shown, are matched by condition *name* and are offered as candidates for you to judge. They are not "the drugs for this code".
