About coding senile systemic SSA amyloidosis
The ICD-10-CM code for senile systemic SSA amyloidosis is E85.82 (Wild-type transthyretin-related (ATTR) amyloidosis).
Within E85.8 (other amyloidosis), E85.82 is specifically for Wild-type transthyretin-related (ATTR) amyloidosis. Related codes cover light chain (AL) amyloidosis (E85.81) and other amyloidosis (E85.89).
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.
In MS-DRG v44.0, it is part of the grouping logic for DRG 545 (Connective Tissue Disorders with MCC, relative weight 2.3892), DRG 546 (Connective Tissue Disorders with CC, relative weight 1.1745) and DRG 547 (Connective Tissue Disorders without CC/MCC, relative weight 0.7526), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
