Patient presents with complaints consistent with spongiotic dermatitis.  The presenting symptoms include erythema, edema, pruritus, and oozing or crusting lesions.  The affected skin exhibits spongiosis on histopathological examination.  Differential diagnoses considered include atopic dermatitis, contact dermatitis, nummular eczema, and seborrheic dermatitis.  The location and morphology of the lesions, along with patient history including potential allergen exposure, family history of atopy, and any recent medication use, were considered in the diagnosis.  Treatment plan includes topical corticosteroids, emollients, and identification and avoidance of triggering allergens if applicable. Patient education provided on proper skin care, including gentle cleansing and moisturizing techniques.  Follow-up scheduled to assess treatment response and adjust management as needed.  ICD-10 code L20.8 (Other specified eczema and dermatitis) or a more specific code if applicable, such as L23 (Allergic contact dermatitis) or L30.9 (Dermatitis, unspecified), will be used for billing purposes.  CPT codes for the evaluation and management visit, along with any procedures performed, will also be documented.  The patient's prognosis is generally good with appropriate management and adherence to the treatment plan.
