HCPCS G8427: Clinician Attestation of Medication Review
HCPCS Level II code G8427 denotes clinician attestation that the patient’s current medication list was obtained, updated, or reviewed and documented in the medical record. This code captures a routine but important safety and care-continuity task: verifying medications to reduce errors, adverse drug events, and gaps in treatment. National attention on medication reconciliation ties this code to quality reporting and care coordination efforts across payers.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of what the code represents, the clinical contexts where it is used, and how it fits into documentation and quality workflows. The publication also outlines common modifiers and where to find additional coding relationships. Benchmarks and policy updates are summarized to provide context on payer expectations and reporting relevance. Clinical context covers roles of clinicians performing medication review and typical ambulatory sites of service.

Clinical & Coding Specifications
Clinical Context
A primary care clinician or ambulatory care pharmacist performs medication reconciliation during an outpatient visit. The patient is an adult with multiple chronic conditions (for example, hypertension, type 2 diabetes, and chronic obstructive pulmonary disease) and presents for a routine follow-up after a recent hospitalization. The clinician reviews the patient’s current medication list in the electronic health record, asks the patient or caregiver about prescription, over-the-counter, and herbal products, documents any changes, and updates dosages and adherence issues in the medical record. The clinician attests to having obtained, updated, or reviewed the patient’s current medications in the chart and signs the note, supporting billing with G8427 for the attestation of documentation. Typical workflow steps: verification of last medication list, patient interview to reconcile discrepancies, update orders or send medication change communications to the pharmacy or care team, and documentation of reconciliation and attestation in the medical record.
