Which MS-DRGs does Q76.6 group to?

Q76.6 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, Q76.6 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together

  • short rib syndrome (Q77.2)

Inclusion terms

Alternative wording in documentation that is classified to Q76.6.

  • Accessory rib
  • Congenital absence of rib
  • Congenital fusion of ribs
  • Congenital malformation of ribs NOS

Excludes1 — never code together — inherited from Q76

The conditions below can never be reported together with Q76.6 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 musculoskeletal deformities of spine and chest (Q67.5-Q67.8)

Excludes2 — not included here — inherited from Chapter 17

The conditions below are not part of Q76.6, but a patient may have both at the same time. When documentation supports it, Q76.6 and the excluded code may both be reported.

  • inborn errors of metabolism (E70-E88)

How long has Q76.6 existed?

Q76.6 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.
