In our EHR, ICD-9 diagnosis code 311 maps to ICD-10 diagnosis code F32.9. Since patients with a 311 diagnosis aren’t included in the denominator for the depression measures, shouldn’t patients with a F32.9 diagnosis be excluded?
No. The ICD-10 diagnosis code F32.9 is defined as “major depressive disorder, single episode, unspecified.” This diagnosis does meet the intent of the measure and IS included in the denominator definition for the depression measures.
The conversion (or mapping) from ICD-9 codes to ICD-10 codes is not a perfect translation where direct relationships and alignment of definitions always exist. Another code that maps to ICD-10 F32.9 is ICD-9 296.20: “major depressive affective disorder, single episode, unspecified.” This diagnosis code also meets the intent of the measure and has always been included in the definition. The mapping issue of 311 stems from there not being an equivalent ICD-10 code defined as “depressive disorder, not elsewhere classified.” This is because ICD-10 provides much more specificity and many more diagnosis codes to choose from. If the definition of F32.9 isn’t the appropriate diagnosis for a patient, then another, more appropriate, diagnosis code should be used for the patient.
