About coding Panarteritis nodosa
The ICD-10-CM code for Panarteritis nodosa is M30.0 (Polyarteritis nodosa). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on M30.0.
Within M30 (polyarteritis nodosa and related conditions), M30.0 is specifically for polyarteritis nodosa. Related codes cover polyarteritis with lung involvement [Churg-Strauss] (M30.1), juvenile polyarteritis (M30.2), mucocutaneous lymph node syndrome [Kawasaki] (M30.3) and other conditions related to polyarteritis nodosa (M30.8).
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.
