Graft-versus-host disease, unspecified

Filed alongside this entry 585

under Disease, diseased

Index entries, exactly as the book files them. This says they are listed together — not that any of them is documented in your chart.

Billable FY2027 2026-10-01 → 2027-09-30
This is the unspecified option. 3 more specific codes sit alongside it. Worth checking whether the documentation supports one of them.
How to use this page

Everything the published sources say about one code, on one page.

  1. Read the Excludes1 block first — it is the one that stops you coding this at all alongside another code.
  2. 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.
  3. 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.
  4. Guideline text is quoted verbatim with its section number and page, so you can check it against the published document.
  5. 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".
