Billable codes in this category
Each of the codes below is billable. Choose the one that most accurately describes the patient's diagnosis.
SLE confirmed to involve at least one organ or body system, but the specific organ or system affected has not yet been identified or documented in the medical record.
M32.11 identifies endocarditis occurring as a direct manifestation of systemic lupus erythematosus (SLE), also called Libman-Sacks disease — the nonbacterial verrucous endocarditis characteristic of SLE.
Pericarditis occurring as a direct manifestation of systemic lupus erythematosus, classified under SLE with organ or system involvement (parent M32.1).
M32.13 identifies documented pulmonary manifestations arising directly from systemic lupus erythematosus, classifying the lung as the specifically involved organ within the broader M32.1 organ-involvement subcategory.
M32.14 identifies glomerular disease — including lupus nephritis — occurring as a direct manifestation of systemic lupus erythematosus (SLE), classified under SLE with organ or system involvement.
M32.15 identifies tubulo-interstitial nephropathy as the specific renal manifestation of systemic lupus erythematosus — distinct from glomerular disease — affecting the renal tubules and surrounding interstitium in the setting of confirmed SLE.
M32.19 captures systemic lupus erythematosus with documented involvement of an organ or system not individually named in codes M32.11–M32.15 — covering manifestations such as neuropsychiatric (lupus encephalitis), musculoskeletal, hematologic, dermatologic, hepatic, or ocular involvement when those specific sites lack a dedicated subcategory.
