Q89.7 — Multiple congenital malformations, not elsewhere classified

BillableUnspecifiedCC

Is Q89.7 billable?

Yes, but Q89.7 is an unspecified code. Q89.7 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, Q89.7 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting Q89.7 — the more specific alternatives are listed below.

Which MS-DRGs does Q89.7 group to?

Q89.7 sits in MDC 08 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 564Other Musculoskeletal System and Connective Tissue Diagnoses with MCCmedical
  • 565Other Musculoskeletal System and Connective Tissue Diagnoses with CCmedical
  • 566Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCCmedical

As a secondary diagnosis, Q89.7 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together

The conditions below can never be reported together with Q89.7 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • congenital malformation syndromes affecting multiple systems (Q87.-)

Inclusion terms

Alternative wording in documentation that is classified to Q89.7.

  • Multiple congenital anomalies NOS
  • Multiple congenital deformities NOS

Excludes2 — not included here — inherited from Chapter 17

The conditions below are not part of Q89.7, but a patient may have both at the same time. When documentation supports it, Q89.7 and the excluded code may both be reported.

  • inborn errors of metabolism (E70-E88)

How long has Q89.7 existed?

Q89.7 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.
