Z79.899 — Other long term (current) drug therapy
ICD-10-CM
Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- The medical record must contain documentation fully supporting medical necessity, including relevant medical history, physical examination, and results of pertinent diagnostic tests or procedures.
- Each echocardiography service requires a formal written report with interpretation retained in the record and copies of image documentation (paper or electronic) available for review.
- A complete study must include M-mode and/or 2D measurements of LV end-diastolic diameter, LV end-systolic diameter, LV wall thickness, left atrial diameter, aortic valve excursion, and a qualitative description of LV function, or valid substitutes such as LV volumes, ejection fraction, and mass.
- Doppler interrogation must state the modes used and provide both qualitative and quantitative information.
Key Coverage Criteria
- Transthoracic echocardiography (TTE) is covered when the patient's medical record documents medical necessity consistent with the LCD indications for TTE.
- Contrast (contrast-enhanced) echocardiography is covered when conventional echocardiographic studies were inconclusive and contrast enhancement is needed to complete diagnostic evaluation.
- Repeat echocardiographic studies are covered to monitor changes in cardiac structure or function when there is a change in clinical status or when disease progression is suspected.
- ESA therapy is indicated for anemia due to decreased erythropoietin production or relative erythropoietin resistance, e.g., anemia of chronic renal failure or end-stage renal disease (ESRD).
- ESA therapy is indicated to maintain hematologic targets with typical goals of hematocrit 30.0-36.0% (hemoglobin 10.0-12.0 g/dL) and the medical record should document rationale for dose changes or values outside these ranges.
- ESA therapy may be considered for other chronic conditions not specifically addressed by this policy when the patient demonstrates considerable transfusion dependence and anemia-related symptoms and documentation supports reasonable and necessary use.
