About coding thoracic rib high
The ICD-10-CM code for thoracic rib high is Q76.6 (Other congenital malformations of ribs).
Within Q76, choose Q76.6 (Other congenital malformations of ribs) only when documentation doesn't support a more specific option: spina bifida occulta (Q76.0), Klippel-Feil syndrome (Q76.1), congenital spondylolisthesis (Q76.2), congenital scoliosis due to congenital bony malformation (Q76.3), other congenital malformations of spine, not associated with scoliosis (Q76.4), cervical rib (Q76.5), congenital malformation of sternum (Q76.7), other congenital malformations of bony thorax (Q76.8) and 1 more.
Don't report Q76.6 together with the conditions in its Excludes1 note: short rib syndrome (Q77.2).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
Don't confuse with (Excludes1 for Q76.6)
- short rib syndrome (Q77.2)
