Disorders of orbit (H05)

Browse all the diagnosis codes used for disorders of orbit (h05). 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

Enophthalmos - Recession of the eyeball into the orbit.

Exophthalmos - Abnormal protrusion of both eyes; may be caused by endocrine gland malfunction, malignancy, injury, or paralysis of the extrinsic muscles of the eye.

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.

Orbital Myositis - Inflammation of the extraocular muscle of the eye. It is characterized by swelling which can lead to ischemia, fibrosis, or ORBITAL PSEUDOTUMOR.

Orbital Pseudotumor - A nonspecific tumor-like inflammatory lesion in the ORBIT of the eye. It is usually composed of mature LYMPHOCYTES; PLASMA CELLS; MACROPHAGES; LEUKOCYTES with varying degrees of FIBROSIS. Orbital pseudotumors are often associated with inflammation of the extraocular muscles (ORBITAL MYOSITIS) or inflammation of the lacrimal glands (DACRYOADENITIS).

Retrobulbar Hemorrhage - Hemorrhage within the orbital cavity, posterior to the eyeball.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
