L41.9 is a billable ICD-10 code used to specify a medical diagnosis of parapsoriasis, unspecified. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like L41.9 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.

Clinical Information
- Parapsoriasis-. the term applied to a group of relatively uncommon inflammatory, maculopapular, scaly eruptions of unknown etiology and resistant to conventional treatment. eruptions are both psoriatic and lichenoid in appearance, but the diseases are distinct from psoriasis, lichen planus, or other recognized dermatoses. proposed nomenclature divides parapsoriasis into two distinct subgroups, pityriasis lichenoides and parapsoriasis en plaques (small- and large-plaque parapsoriasis).
- Pityriasis Lichenoides-. a subgroup of parapsoriasis itself divided into acute and chronic forms. the acute form is characterized by the abrupt onset of a generalized, reddish-brown, maculopapular eruption. lesions may be vesicular, hemorrhagic, crusted, or necrotic. histologically the disease is characterized by epidermal necrolysis. the chronic form shows milder skin changes with necrosis.
- Large Plaque Parapsoriasis|Parapsoriasis en Plaques-. a variant of parapsoriasis in which the plaques are large.
- Parapsoriasis-. an inflammatory skin disorder of unknown etiology characterized by papules and plaques or scaly patches resembling psoriasis.
- Parapsoriasis Lichenoides|Parapsoriasis Variegata|Poikiloderma Atrophicans Vasculare|Poikilodermic Parapsoriasis|Retiform Parapsoriasis-. a rare condition that stimulated chronic radiodermatitis. it is considered a variant of mycosis fungoides.
- Small Plaque Parapsoriasis-. a variant of parapsoriasis in which the plaques are small.

Patient Education
Skin Conditions
Your skin is your body's largest organ. It covers and protects your body. Your skin:
- Holds body fluids in, preventing dehydration
- Keeps harmful microbes out, preventing infections
- Helps you feel things like heat, cold, and pain
- Keeps your body temperature even
- Makes vitamin D when the sun shines on it
Anything that irritates, clogs, or inflames your skin can cause symptoms such as redness, swelling, burning, and itching. Allergies, irritants, your genetic makeup, and certain diseases and immune system problems can cause rashes, hives, and other skin conditions. Many skin problems, such as acne, also affect your appearance.

Psoriasis
