Which MS-DRGs does Q20.0 group to?

Q20.0 sits in MDC 05 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 306Cardiac Congenital and Valvular Disorders with MCCmedical
  • 307Cardiac Congenital and Valvular Disorders without MCCmedical

As a secondary diagnosis, Q20.0 is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG.

How is Q20.0 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to Q20.0. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Common › arterial trunk
  • Common › truncus
  • Persistence, persistent › truncus arteriosus or communis (congenital)
  • Truncus › arteriosus
  • Truncus › communis
  • Malposition › congenital › arterial trunk

Excludes1 — never code together

The conditions below can never be reported together with Q20.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • aortic septal defect (Q21.4)

Inclusion terms

Alternative wording in documentation that is classified to Q20.0.

  • Persistent truncus arteriosus

Excludes1 — never code together — inherited from Q20

The conditions below can never be reported together with Q20.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • dextrocardia with situs inversus (Q89.3)
  • mirror-image atrial arrangement with situs inversus (Q89.3)

Excludes2 — not included here — inherited from Chapter 17

The conditions below are not part of Q20.0, but a patient may have both at the same time. When documentation supports it, Q20.0 and the excluded code may both be reported.

  • inborn errors of metabolism (E70-E88)

How long has Q20.0 existed?

Q20.0 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.

Which codes are confused with Q20.0?

ICD-10-CM declares these codes mutually exclusive with Q20.0 — exactly one of each pair can be correct for a given encounter.
