Cellulitis and acute lymphangitis (L03)

Browse all the diagnosis codes used for cellulitis and acute lymphangitis (l03). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Broad Ligament - A broad fold of peritoneum that extends from the side of the uterus to the wall of the pelvis.

Cellulitis - An acute, diffuse, and suppurative inflammation of loose connective tissue, particularly the deep subcutaneous tissues, and sometimes muscle, which is most commonly seen as a result of infection of a wound, ulcer, or other skin lesions.

Orbital Cellulitis - Inflammation of the loose connective tissues around the ORBIT, bony structure around the eyeball. It is characterized by PAIN; EDEMA of the CONJUNCTIVA; swelling of the EYELIDS; EXOPHTHALMOS; limited eye movement; and loss of vision.

Parametritis - Inflammation of the parametrium, the connective tissue of the pelvic floor, extending from the subserous coat of the uterus laterally between the layers of the BROAD LIGAMENT.

Paronychia - An inflammatory reaction involving the folds of the skin surrounding the fingernail. It is characterized by acute or chronic purulent, tender, and painful swellings of the tissues around the nail, caused by an abscess of the nail fold. The pathogenic yeast causing paronychia is most frequently Candida albicans. Saprophytic fungi may also be involved. The causative bacteria are usually Staphylococcus, Pseudomonas aeruginosa, or Streptococcus. (Andrews' Diseases of the Skin, 8th ed, p271)
