For services that require a referring/ordering physician, the referring/ordering physician's name and NPI must be reported on the claim.
The claim must include a valid ICD-10-CM diagnosis code that best describes the patient's condition for which the urine drug test was performed.
For diagnostic urine drug tests, report the test result if known; if the result is not known, report the symptoms that prompted the performance of the test.
This billing and coding guidance complements Local Coverage Determination L35724 and providers should follow LCD L35724 in conjunction with NCCI/OPPS rules when preparing claims.

Patient requires active psychiatric partial hospitalization (PHP) with an individualized written plan of care developed by a physician in consultation with appropriate staff and a multidisciplinary team.
Patient requires a minimum of 20 hours per week of therapeutic services as evidenced by the plan of care.
On admission, a physician (MD/DO) certifies that the patient would require inpatient psychiatric hospitalization if PHP services were not provided and attests that services are furnished while the patient is under physician care.
Initial psychiatric evaluation (including medical history and physical examination) is performed and placed in the chart within 48 hours of admission to establish medical necessity.
Diagnosis coding (ICD-10-CM) that best describes the patient's condition is required on the claim to support medical necessity.
IPF services are 'active treatment' when provided under an individualized treatment or diagnostic plan developed by a physician with appropriate other disciplines based on a thorough evaluation of the patient's strengths and disabilities.
