`T40.995D`, Adverse effect of other psychodysleptics [hallucinogens], subsequent encounter

ICD-10-CM

Prior Authorization

No Prior Auth Required

Covered without prior authorization (high confidence)

Documentation Required

This article provides billing/coding guidelines that complement Local Coverage Determination L34417 for CT of the head; consult LCD L34417 for specific coverage, coding, and documentation requirements.
When a limited or follow-up echocardiogram is performed, document the targeted cardiac problem/region and bill using the appropriate CPT code (93308 or 93321).
If the study is a screening exam, document and bill with the appropriate screening ICD-10 code; document any abnormal findings and use the resulting diagnosis for subsequent billing when applicable.

Key Coverage Criteria

Follow-up or limited transthoracic echocardiography performed to evaluate a single specified cardiac problem or region must be billed with CPT 93308.
Limited Doppler/follow-up echocardiographic studies (for targeted velocity or gradient assessment) should be billed with CPT 93321 (e.g., tricuspid regurgitant velocity to estimate pulmonary artery systolic pressure or sequential transmitral velocity in mitral stenosis).
Urine drug testing (UDT) and drugs-of-abuse testing are covered when reasonable and necessary per LCD L35006 and ordered on an individual patient basis by the treating clinician with medical-record documentation of medical necessity.
Patients with a documented diagnosis consistent with substance use disorder (SUD) may qualify for an exception to the standard presumptive UDT annual limits.
RAST type tests are covered when medically necessary and supported by the related Local Coverage Determination (LCD) and current medical literature or standards of practice.
Monitored Anesthesia Care (MAC) is medically necessary when the patient has one or more documented diagnoses listed as supporting medical necessity (e.g., F91.9, G97.81, T81.9XXA, T88.8XXA, F79) and the diagnosis is matched to the anesthesia/CPT/HCPCS procedure performed.
