Other localized connective tissue disorders (L94)

Browse all the diagnosis codes used for other localized connective tissue disorders (l94). 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

Ainhum - Spontaneous autoamputation of the fourth or fifth toe.

Calcinosis Cutis - Pathological deposition of calcium in the skin and subcutaneous tissue. Excessive calcification of the skin may be associated with underlying diseases that cause tissue damage (e.g., EHLERS-DANLOS SYNDROME; PSEUDOXANTHOMA ELASTICUM; ROTHMUND-THOMSON SYNDROME; and WERNER SYNDROME) or that cause abnormal calcium and phosphate metabolism (e.g., CALCIPHYLAXIS; CHRONIC KIDNEY FAILURE; HYPERPARATHYROIDISM; and SARCOIDOSIS).

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.

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.
