    HCPCS Level II M1112: Documentation of Degenerative Neurological Diagnosis

    HCPCS Level II code M1112 documents that a patient has a diagnosis of a degenerative neurological condition such as amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), or Parkinson’s disease identified at any time before or during the episode of care; this code represents a diagnostic documentation service typically used in clinical charting and care coordination and is applicable to evaluations and care planning provided in outpatient clinics, neurology practices, home health visits, and other ambulatory or home-based settings.

    For related coverage guidance, see recent payer policy updates: Adult Foster Care, Group Adult Foster Care Clinical Coverage Criteria, Home Health Care Payment Policy.

    Clinical & Coding Specifications

    Clinical Context

    A typical patient is a 58-year-old individual with progressive motor symptoms referred to a home health agency for supportive services after diagnosis of a degenerative neurological condition such as amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), or Parkinson disease. The agency documents presence of the degenerative neurological diagnosis in the patient’s medical record to establish eligibility for care models or specialized equipment and to support care planning. Clinical workflow includes verification of prior neurologist or hospital documentation of the diagnosis, review of the history and neurologic findings, reconciliation of medications (antispasmodics, disease-modifying therapies, dopaminergic agents), and recording the diagnosis in the home health certification/recertification or episode record. Typical interactions occur in the patient’s residence, assisted living, or long-term care facility and involve communication with the treating neurologist, primary care provider, and payer case managers (e.g., Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, Medicare). Documentation supports care planning for mobility aids, therapy referrals (physical, occupational, speech), durable medical equipment, and safety interventions during the episode of care.
