Yes

Do not code cellulitis. Code the presenting symptoms and/or differential diagnosis.
When to use each related code
| Description |
|---|
| Leg cellulitis: Bacterial skin infection |
| Erysipelas: Superficial skin infection |
| DVT: Blood clot in deep leg vein |
Coding cellulitis without specifying the causative organism when documented leads to lower specificity and potential DRG misclassification.
Coding cellulitis based on symptoms alone without definitive diagnosis may lead to inaccurate claims and compliance issues.
Failing to code laterality (right or left leg) for leg cellulitis leads to coding errors and impacts data analysis.
Patient presents with signs and symptoms consistent with leg cellulitis. Onset of symptoms reported as [duration] ago. Affected area involves the [location on leg, e.g., right lower leg, left medial thigh]. Patient reports [symptoms, e.g., localized pain, erythema, warmth, edema, tenderness]. [Optional: mention accompanying symptoms such as fever, chills, malaise, lymphadenopathy, or red streaks]. Physical examination reveals [objective findings, e.g., well-demarcated erythema, palpable induration, increased skin temperature, edema measuring x cm, tenderness to palpation]. [If applicable: Wound noted with [description], potential source of infection identified as [source].] No signs of crepitus or fluctuance. Differential diagnoses considered include deep vein thrombosis, contact dermatitis, and erysipelas. Based on clinical presentation, a diagnosis of leg cellulitis is made. Treatment plan includes [antibiotic prescribed, e.g., oral cephalexin, intravenous vancomycin] for [duration]. Patient education provided regarding wound care, elevation of affected limb, pain management with [analgesic recommended], and signs and symptoms to monitor for potential complications such as abscess formation or sepsis. Follow-up appointment scheduled in [duration] to assess response to treatment. ICD-10 code L03.111 (Cellulitis of lower leg) or other appropriate code assigned based on specific location. Medical necessity for prescribed antibiotic documented.
