About coding Beals syndrome
The ICD-10-CM code for Beals syndrome is Q87.40 (Marfan syndrome, unspecified).
Within Q87.4, choose Q87.40 (unspecified) only when documentation doesn't support a more specific option: with cardiovascular manifestations (Q87.41), with ocular manifestations (Q87.42) and with skeletal manifestation (Q87.43).
Use an additional code(s) to identify all associated manifestations.
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.
