ICD-10 Code L94.9 – Localized Connective Tissue Disorder, Unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L94.9 – Localized connective tissue disorder, unspecified
What it is
L94.9 identifies a localized disorder of connective tissue when the record does not specify a more exact diagnosis. Use it for a nonspecific localized connective tissue condition documented by the clinician.
Clinical signs
Clinical features vary; refer to documentation. Findings may include localized skin or tissue changes consistent with a connective tissue disorder, but the chart should support the nonspecific diagnosis.
When to use this code
Use this code when the provider documents a localized connective tissue disorder and does not name a more specific condition. It is appropriate when the record supports a connective tissue process, but details are insufficient for a more precise code. Check documentation if the diagnosis is unclear.
Do not use for
Do not use L94.9 when the chart identifies a specific connective tissue disease, such as scleroderma or another named disorder. Do not use it for generalized or systemic conditions without documentation of a localized process.
Coding tip
Query for specificity whenever the note says “connective tissue disorder” without a clearer diagnosis.
