Valid for Submission
L10.9 is a billable diagnosis code used to specify a medical diagnosis of pemphigus, unspecified. The code L10.9 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code L10.9 might also be used to specify conditions or terms like iga pemphigus, pemphigus or pemphigus of vulva.
Unspecified diagnosis codes like L10.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code L10.9 are found in the index:
- - Pemphigus - L10.9
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- IgA pemphigus
- Pemphigus of vulva
- PEMPHIGUS-. group of chronic blistering diseases characterized histologically by acantholysis and blister formation within the epidermis.
- PEMPHIGUS BENIGN FAMILIAL-. an autosomal dominantly inherited skin disorder characterized by recurrent eruptions of vesicles and bullae mainly on the neck axillae and groin. mutations in the atp2c1 gene encoding the secretory pathway ca2++/mn2++ atpase 1 spca1 cause this disease. it is clinically and histologically similar to darier disease both have abnormal unstable desmosomes between keratinocytes and defective calcium transporting atpases. it is unrelated to pemphigus vulgaris though it closely resembles that disease.
- DESMOGLEIN 1-. a desmosomal cadherin that is an autoantigen in the acquired skin disorder pemphigus foliaceus.

|MS-DRG||MS-DRG Title||MCD||Relative Weight|
|595||MAJOR SKIN DISORDERS WITH MCC||09||2.0121|
|596||MAJOR SKIN DISORDERS WITHOUT MCC||09||0.9892|
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert L10.9 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code L10.9 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Pemphigus is an autoimmune disorder. If you have it, your immune system attacks healthy cells in your skin and mouth, causing blisters and sores. No one knows the cause. Pemphigus does not spread from person to person. It does not appear to be inherited. But some people's genes put them more at risk for pemphigus.
Pemphigoid is also an autoimmune skin disease. It leads to deep blisters that do not break easily. Pemphigoid is most common in older adults and may be fatal for older, sick patients.
Doctors diagnose pemphigus with a physical exam, a biopsy, and blood tests. The treatment of pemphigus and pemphigoid is the same: one or more medicines to control symptoms. These may include
- Steroids, which reduce inflammation
- Drugs that suppress the immune system response
- Antibiotics to treat associated infections
