Valid for Submission
L12.9 is a billable diagnosis code used to specify a medical diagnosis of pemphigoid, unspecified. The code L12.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code L12.9 might also be used to specify conditions or terms like chronic localized pemphigoid, localized pemphigoid or pemphigoid.
Unspecified diagnosis codes like L12.9 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 L12.9 are found in the index:
- - Pemphigoid - L12.9
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Chronic localized pemphigoid
- Localized pemphigoid
- PEMPHIGOID GESTATIONIS-. an itching autoimmune bullous skin disease that occurs during the last two trimesters of pregnancy and puerperium. it also affects non pregnant females with tissue of placenta origin such as choriocarcinoma; or hydatidiform mole. it exhibits antigenic and clinical similarity to bullous pemphigoid pemphigoid bullous. this disease does not involve herpes viruses old name herpes gestationis.
- PEMPHIGOID BENIGN MUCOUS MEMBRANE-. a chronic blistering disease with predilection for mucous membranes and less frequently the skin and with a tendency to scarring. it is sometimes called ocular pemphigoid because of conjunctival mucous membrane involvement.
- PEMPHIGOID BULLOUS-. a chronic and relatively benign subepidermal blistering disease usually of the elderly and without histopathologic acantholysis.

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 L12.9 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code L12.9 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
