ICD-10 Code K14.2 – Median rhomboid glossitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K14.2 – Median rhomboid glossitis
What it is
Median rhomboid glossitis is a localized, usually painless lesion on the midline of the tongue. It is coded when documentation identifies this specific inflammatory-appearing lingual condition.
Clinical signs
Typical findings include a smooth, red, depapillated patch on the central dorsal tongue, often near the circumvallate papillae. Clinical features vary; refer to documentation.
When to use this code
Use K14.2 when the provider documents median rhomboid glossitis by name or clearly describes a characteristic midline tongue lesion. Apply it for confirmed diagnosis, not for vague mouth pain or unspecified tongue changes. Check documentation if the note suggests another oral lesion.
Do not use for
Do not use this code for generalized glossitis, oral candidiasis, or other tongue disorders without documentation of median rhomboid glossitis. If the lesion is not specifically identified, code the documented condition instead.
Coding tip
Code the exact documented tongue diagnosis and avoid assuming this lesion from appearance alone.
