2025 ICD-10-CM code M31.30
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Diseases of the musculoskeletal system and connective tissue - Systemic connective tissue disorders Chapter 13: Diseases of the musculoskeletal system and connective tissue Feed
Wegener's granulomatosis without renal involvement.
Medical necessity is established by the presence of clinical findings consistent with Wegener's granulomatosis, including characteristic symptoms, positive laboratory tests (e.g., ANCA), and histopathologic evidence of granulomatous vasculitis.The absence of renal involvement is crucial for accurate coding.
Diagnosis typically involves patient history, physical examination, blood tests (e.g., for antineutrophil cytoplasmic antibodies (ANCA)), and tissue biopsy.Treatment often includes immunosuppressants like glucocorticoids (e.g., prednisone), cyclophosphamide, and methotrexate.

In simple words: This code describes a rare condition called Wegener's granulomatosis where the blood vessels become inflamed, mostly in the nose, sinuses, lungs, and throat, but without affecting the kidneys.It's an autoimmune disease, meaning the body's immune system attacks itself.
M31.30, Wegener's granulomatosis without renal involvement, is a rare, systemic autoimmune disorder characterized by necrotizing granulomatous vasculitis affecting the upper and lower respiratory tracts.This specific code indicates the absence of kidney involvement, a key differentiator from the more severe, classic form of the disease.The vasculitis causes inflammation and damage to blood vessels, leading to various symptoms depending on the affected organs.
Example 1: A 55-year-old male presents with chronic sinusitis, nasal crusting, and recurring epistaxis.Blood tests reveal elevated ANCA levels. Nasal biopsy confirms granulomatous vasculitis. Renal function tests are normal.Code M31.30 is assigned., A 60-year-old female experiences persistent cough, dyspnea, and hemoptysis.Imaging reveals lung nodules consistent with granulomatosis.ANCA levels are positive. Renal function is within normal limits. Code M31.30 is used., A 40-year-old male presents with recurrent ear infections, hearing loss, and nasal inflammation.Biopsy shows granulomatous inflammation of the blood vessel walls.Kidney function is unaffected. Code M31.30 is appropriate.
Detailed patient history including symptoms, duration, and severity.Results of relevant laboratory tests (e.g., ANCA levels, complete blood count, renal function tests).Radiologic imaging findings (e.g., chest X-ray, CT scans).Histopathological results from tissue biopsy.Treatment plan and response.
** Wegener's granulomatosis has been renamed Granulomatosis with Polyangiitis (GPA).While M31.30 remains valid,consider using the appropriate GPA code if available in your coding system to reflect current medical terminology.
