Coder workflow for Q79.6

MedCoder structured workflow — derived from this code’s own official record

Before you code Q79.6

  1. Q79.6 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

  1. Does the documentation support one of the more specific codes beneath Q79.6?
    Yes → Select that code and continue the checks below on its own page.
    No → Q79.6 cannot be reported as written; query for the specificity its subcategory needs.

Consider Q79.6. 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.

Code Overview

Ehlers-Danlos syndromes is a non-billable ICD-10-CM category code (Q79.6). A more specific billable subcode must be selected for claims submission.

Indexed Clinical Terms (1)

Official source data — entries quoted as published, in the Index’s own lookup phrasing

Clinical term phrases from the official ICD-10-CM Index to Diseases and Injuries that map to this code. These are alphabetic-index entries shown as the Index writes them — lookup phrasing, not necessarily the wording of a final diagnosis.

Verify Before Coding

From the code registry, the Medicare Code Editor, and the MS-DRG Definitions Manual. Check it against a full claim in Claim Check.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name Q79.6 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 3 Excludes1 notes across 2 chapters: M24.3 — Pathological dislocation of joint, not elsewhere classified (via Q79.-), Q82.8 — Other specified congenital malformations of skin, Q87.A — Loeys-Dietz syndrome.

These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.

Referenced by 20 Excludes2 notes across 2 chapters: E70 — Disorders of aromatic amino-acid metabolism, E70-E88 — Metabolic disorders (E70-E88), E71 — Disorders of branched-chain amino-acid metabolism and fatty-acid metabolism, E72 — Other disorders of amino-acid metabolism, E73 — Lactose intolerance, E74 — Other disorders of carbohydrate metabolism, E75 — Disorders of sphingolipid metabolism and other lipid storage disorders, E76 — Disorders of glycosaminoglycan metabolism, E77 — Disorders of glycoprotein metabolism, E78 — Disorders of lipoprotein metabolism and other lipidemias, E79 — Disorders of purine and pyrimidine metabolism, E80 — Disorders of porphyrin and bilirubin metabolism, E83 — Disorders of mineral metabolism, E84 — Cystic fibrosis, E85 — Amyloidosis, E86 — Volume depletion, E87 — Other disorders of fluid, electrolyte and acid-base balance, E88 — Other and unspecified metabolic disorders, M35.7 — Hypermobility syndrome, M95 — Other acquired deformities of musculoskeletal system and connective tissue (via Q79.-).

These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.
