2025 ICD-10-CM code M32.19

Other organ or system involvement in systemic lupus erythematosus. Use additional code(s) to identify the specific organ or system involved.

Code M32.19 should be used when the documentation supports the involvement of an organ or system in SLE, but the specific affected organ or system is not documented. Code M32.10 should be used if the documentation does not indicate any specific organ or system involvement. Always code to the highest level of specificity. If the specific organ/system involved is documented, use the appropriate code for that involvement.

Medical necessity for this code is established by the diagnosis of SLE and the presence of signs or symptoms indicating organ or system involvement. The medical record must clearly link the organ or system involvement to SLE.

The provider should document the type of organ or system involvement, as well as any associated symptoms and treatments. Diagnosis is based on patient history, physical exam, and laboratory tests like complete blood count (CBC), antinuclear antibody tests (ANA), urinalysis, and tissue biopsies.

IMPORTANT:Use additional codes to identify the specific organ or system involvement, such as encephalitis (G05.3). Do not use this code if the specific organ or system involvement is documented. Instead, use the appropriate code for the specific condition.

In simple words: This code indicates that a patient with systemic lupus erythematosus (SLE), also known as lupus, has involvement of other organs or systems in their body, but the specific organ or system is not documented. Lupus is a long-lasting autoimmune disease where the body's immune system mistakenly attacks its own tissues and organs.

Organ or system involvement occurs as a complication of systemic lupus erythematosus, an inflammatory autoimmune disease of the connective tissues affecting the joints and multiple organs, including the skin, heart, lungs, kidneys, and nervous system. The provider does not document the specific organ or system involved.This code should be used in conjunction with additional codes to specify the affected organ or system.

Example 1: A patient with SLE presents with new neurological symptoms, but the specific neurological condition has not yet been diagnosed. M32.19 would be used along with a code for the neurological symptoms., A patient with SLE has documented kidney involvement and newly developed liver inflammation. M32.19 is used with codes specifying both kidney and liver conditions., A patient with SLE and documented lung involvement experiences an unexplained fever. M32.19 may be used to indicate a possible SLE-related complication along with code for the fever (R50.9).

Documentation should include the patient's history, physical examination findings, and laboratory results. Details of organ or system involvement should be specified if known. If the specific organ or system is unknown, this should also be clearly documented.
