Approximate ICD-9-CM (GEMs)

• 583.81 Nephritis and nephropathy, not specified as acute or chronic, in diseases classified elsewhere (approximate)

Medicare Code Edits (MCE v43.1 (April 2026))

• Manifestation codes as principal diagnosis: Manifestation codes describe the manifestation of an underlying disease, not the disease itself, and are not allowed as principal diagnosis.
