Entering Numerator Data

To report on this measure, you must order or perform an A1c test using CPT code 83036 or 83037 and then either enter the test results or receive them through an interface and give them a status of Resulted or Approved. 

The A1c test results not received through an interface must be entered as discrete, quantifiable data. Enter the results in the Patients Results window using a lab template enabling you to enter the HGB A1c value. Results stored in the database as text notes or image file cannot be used for PQRS reporting. 

You must associate a LOINC code to the A1C test item on each lab template for both manually entered and electronic results. LOINC codes for this result are 17856-6, 4549-2, or 4548-4.

Diagnosis (ICD-9) Codes

An appropriate diagnosis (ICD-9) code (or narrative description) must be indicated for each service or supply billed under Medicare Part B. ICD-9-CM is an acronym for International Classification of Diseases, 9th Revision, Clinical Modification.

When a patient presents with an undiagnosed illness, the ICD-9 code is determined by the "signs and symptoms" present. Symptoms are defined as what the patient tells the  physician. Signs are what the physician observes as part of his examination of the patient.

Definitive ICD-9 codes should only be assigned and recorded in the medical record after a diagnosis is clearly determined. Terms such as "rule out", "probable", and "suspected" should NOT be used since they can not be coded as such and may be interpreted as a firm diagnosis by a third party payer.
