Is ICD-10-CM code M30 billable?

No, M30 (Polyarteritis nodosa and related conditions) is a non-billable ICD-10-CM code. It must be coded to a more specific subcategory before it can be used for reimbursement.

What chapter does ICD-10-CM code M30 belong to?

M30 belongs to Chapter 13 of the ICD-10-CM tabular list: M00–M99 (Diseases of the Musculoskeletal System and Connective Tissue).

M30Not billable, use a more specific code below

Polyarteritis nodosa and related conditions

In Systemic connective tissue disorders (M30-M36), chapter 13: Diseases of the Musculoskeletal System and Connective Tissue

5 billable codes under M30: all are a CC; all map to HCC 94 (Systemic Lupus Erythematosus and Other Specified Systemic Connective Tissue Disorders), HCC 93 (Rheumatoid Arthritis and Other Specified Inflammatory Rheumatic Disorders), HCC 278 (Idiopathic Pulmonary Fibrosis and Lung Involvement in Systemic Sclerosis).A CC or MCC (major CC) is a secondary diagnosis that raises the MS-DRG payment. An HCC counts toward a Medicare Advantage patient's risk score.

All codes under M30

M30 can't be used on a claim. Pick a billable code below; grey headings group them.

M30 MS-DRGs

As the principal diagnosis, the billable codes under M30 group to MS-DRG 545, 546, 547, 542, 543, or 544 (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.

DRG 545 Connective Tissue Disorders with MCC (4 of 5 codes)
DRG 546 Connective Tissue Disorders with CC (4 of 5 codes)
DRG 547 Connective Tissue Disorders without CC/MCC (4 of 5 codes)
DRG 542 Pathological Fractures and Musculoskeletal and Connective Tissue Malignancy with MCC (1 of 5 codes)
DRG 543 Pathological Fractures and Musculoskeletal and Connective Tissue Malignancy with CC (1 of 5 codes)
DRG 544 Pathological Fractures and Musculoskeletal and Connective Tissue Malignancy without CC/MCC (1 of 5 codes)

About the condition

Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.

Vasculitis

Vasculitis is an inflammation of the blood vessels. It happens when the body's immune system attacks the blood vessel by mistake. It can happen because of an infection, a medicine, or another disease. The cause is often unknown.

Code history

Valid since FY2016, when ICD-10-CM took effect on October 1, 2015. No changes since.
