Before you code Q71
- Q71 is not reportable as written. Select the more specific code beneath it that the documentation supports. Codes are reported to the highest level of specificity the classification provides (Guidelines I.B.2).

Choose the right path
- Does the documentation support one of the more specific codes beneath Q71?
Yes → Select that code and continue the checks below on its own page.
No → Q71 cannot be reported as written; query for the specificity its subcategory needs.ReviewQ71.0, Q71.1, Q71.2, Q71.3, Q71.4, Q71.5, Q71.6, Q71.8, Q71.9
Consider Q71. Then confirm the code is valid for the date of service in the Verify section.
Documentation check
- The provider’s diagnostic statement
- Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).
Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

Relationships & Classification
MedCoder structured relationships — computed from published CMS and AHRQ datasets
Other codes that name Q71 or its code family, from the CMS ICD-10-CM tabular instructional notes. Tabular-note edges are stored at the code family level that carries each note.
Referenced by 5 Excludes1 notes across 3 chapters: M21 — Other acquired deformities of limbs, M24.3 — Pathological dislocation of joint, not elsewhere classified, Q68 — Other congenital musculoskeletal deformities, Q74 — Other congenital malformations of limb(s), Z89 — Acquired absence of limb.
These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.
Referenced by 1 Excludes2 note: M95 — Other acquired deformities of musculoskeletal system and connective tissue.
These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.
Contextual Map
Every relationship of Q71 in one view: hierarchy, official tabular instructions in both directions, clinical classification, risk adjustment, MS-DRG participation, index terms and change history — each edge carrying the CMS source it derives from.
