    ICD-10-CM Code For Diseases Of Salivary Glands: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K11 includes inflammatory, obstructive, neoplastic, and other disorders of the salivary glands such as sialadenitis, sialolithiasis, and salivary gland cysts that affect saliva production and gland function. These ICD-10-CM diagnosis codes are used to document clinical presentations involving pain, swelling, infection, obstruction, or mass lesions of the salivary glands, capturing disease severity, gland involvement, and complications. Accurate coding within the ICD-10-CM K11 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM K11: Diseases Of Salivary Glands Overview

    The ICD-10-CM K11 group includes inflammatory, obstructive, and other disorders of the salivary glands affecting saliva production and gland structure. These diagnoses target the major and minor salivary glands within the oral cavity and adjacent tissues. Accurate coding matters for reimbursement because it links clinical findings to appropriate diagnosis codes used in claims and clinical records.

    When to Use

    Use a code from this group when the clinical record documents a diagnosis specifying a salivary gland disorder such as sialadenitis, sialolithiasis, salivary cyst, or a salivary gland neoplasm. Select the most specific code that reflects the anatomic site, laterality when applicable, and any associated complications or sequelae.

    Typical Clinical Scenarios

    • An adult presents to the emergency department with sudden, severe swelling and pain in the floor of the mouth and under the jaw after a few days of reduced oral intake. On exam the submandibular gland is erythematous and tender with purulent drainage from the duct; the patient has fever and difficulty opening the mouth, consistent with an acute bacterial sialadenitis requiring emergent treatment. Typical codes: K11.2, K11.3.
    • A middle‑aged patient in outpatient clinic reports months of intermittent painless swelling of the parotid region that increases with meals, with occasional dry mouth and recurrent small stones palpated at the duct orifice; ultrasound confirms sialolithiasis with obstructive symptoms but no acute infection. This chronic obstructive salivary gland disease is managed conservatively or with referral for stone removal, and a chronic salivary gland disorder code is assigned. Typical codes: K11.5, K11.7.
    • An older adult with long‑standing Sjögren syndrome or radiation history for head-and-neck cancer develops persistent xerostomia, recurrent dental caries, and glandular atrophy leading to functional impairment; the salivary dysfunction is coded as a comorbidity affecting oral health and management decisions. Typical codes: K11.4, K11.9.
