- Billable — Valid for Submission
- Risk Adjusts — HCC 94
- Chronic Condition
M32.14 is a billable ICD-10-CM diagnosis code for glomerular disease in systemic lupus erythematosus. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 545 through 547. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Systemic lupus erythematosus and connective tissue disorders.
For Medicare Advantage risk adjustment, M32.14 maps to CMS-HCC Category 94 (Systemic Lupus Erythematosus and Other Specified Systemic Connective Tissue Disorders) under the V28 model, adding a risk factor of about 0.268 for a community, non-dual, aged beneficiary in payment year 2026.

Clinical InformationClinical
Mesangial Proliferative Glomerulonephritis
a focal inflammation of glomeruli secondary to mesangial cell proliferation and matrix deposition within the mesangium.Focal and Segmental Proliferative Glomerulonephritis
glomerulonephritis characterized by proliferation of endothelial or mesangial cells, affecting the glomeruli in a focal and segmental pattern.
Patient EducationClinical
Kidney Diseases
You have two kidneys, each about the size of your fist. They are near the middle of your back, just below the rib cage. Inside each kidney there are about a million tiny structures called nephrons. They filter your blood. They remove wastes and extra water, which become urine. The urine flows through tubes called ureters.

Questions About M32.14Overview
What is the ICD-10 code for glomerular disease in systemic lupus erythematosus?
The ICD-10-CM code for glomerular disease in systemic lupus erythematosus is M32.14 (sometimes written as M3214). It is billable on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Is M32.14 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report glomerular disease in systemic lupus erythematosus on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does M32.14 group to?
When glomerular disease in systemic lupus erythematosus is the principal diagnosis on an inpatient stay, it groups to MS-DRG 545, 546, 547, with relative weights from 0.8362 to 2.4817 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of M32.14?
Under the General Equivalence Mappings, glomerular disease in systemic lupus erythematosus converts to ICD-9-CM 710.0 (syst lupus erythematosus) and 583.81 (nephritis NOS in oth dis). The mapping is approximate, so confirm the match fits the documentation.
What HCC is M32.14?
M32.14 (glomerular disease in systemic lupus erythematosus) maps to CMS-HCC Category 94 (Systemic Lupus Erythematosus and Other Specified Systemic Connective Tissue Disorders), commonly written as HCC 94, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2026. It mapped to HCC 40 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. In the Part D prescription drug model it maps to RxHCC 84.
Does M32.14 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, M32.14 adds a risk adjustment factor of about 0.268 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.196 to 0.297 depending on the payment segment). A more severe related category (HCC 93) supersedes it when both are reported. See the full factor table on the HCC 94 category page.
