ICD-11 Post-coordination
Post-coordinated ICD-11 clusters बनाएँ और पढ़ें। Inspector किसी भी cluster string को आपके browser में decompose करता है; challenges आपको उसी engine से grade करते हैं जिसे platform की coding automation इस्तेमाल करती है।

ICD-11, ICD-10 का नया संस्करण नहीं है — यह एक अलग ही तरह की चीज़ है, और अभी तक लगभग किसी ने इसका उपयोग नहीं किया है। Kosha explainer में लगभग सात मिनट में बताया गया है कि यह क्या है, हर entity का URI क्यों होता है, और post-coordination का क्या अर्थ है।
ICD-11 explainer पढ़ेंICD-10 is a book that was digitised. ICD-11 is a web service that happens to have a book form — every entity has a URI, and a code can be composed from a stem plus extension codes. That makes ICD-11 competency a different skill from index-and-tabular lookup, which is why it cannot be taught from a book.
Cluster structure — separators, ordering, and whether a string round-trips — is checked in your browser, always. Whether a specific stem sanctions a specific axis is semantic: it lives in WHO's published data and is verified against the ICD-API, which the inspector will tell you it did or did not reach. Code tokens in the drills are supplied with each exercise and are not clinical guidance; the one real cluster (2C25.Z&XK8G&XA9HN5) is WHO's own worked example.
One condition, with detail added
A stem plus two extension codes. This is WHO's own published example.
Stem code
A stem code can stand on its own. It is the part you would have found in the tabular list, and every cluster begins with one. A cluster with no stem is malformed no matter what it means.
Two conditions in one cluster
Note which separator does which job — this is where most mistakes happen.
First stem
The primary condition. Stem order is meaningful — the first stem leads.
These labels describe each token's role in the grammar, not what the code means clinically. What a specific code denotes — and which axes a specific stem actually permits — lives in WHO's published data and is shown, with its title and URI, in the Cluster inspector.
Stem codes and extension codes
A stem code can stand on its own — it is what you would have found in the tabular list. Chapter X extension codes never stand alone; they add severity, anatomy, histopathology, an agent or a medicament to a stem. Post-coordination is the act of composing the two.
The two separators
"&" attaches an extension to the stem before it. "/" ends one stem group and starts the next. Stems always precede their extensions, so a cluster that opens with an X-code is malformed no matter what it means.
Why order must not matter
Two coders who pick the same extensions in a different sequence have coded the same thing. A system that compares raw strings would call them different, so clusters are normalised before they are compared — which is exactly what the inspector's canonical form shows.
Precoordination wins
Where a single category already expresses what you composed, that category must be used instead of the cluster. This is a rule about uniqueness: the same clinical meaning should not have two representations in the data.
For integrators — verifying server-side
The ICD-API's codeinfo endpoint decomposes a cluster string and returns which axes carry which values: GET /icd/release/11/{release}/mms/codeinfo/{cluster}. That is the same call that grades a learner here and that verifies an automatically-generated code — a machine-checkable correctness oracle ICD-10-CM never offered.

Release-binding
ICD-11 ships annual releases, and a cluster valid under one may not be valid under another. Any stored code should carry the release it was built against — coded data that does not record this rots silently.
