O89.09 — Other pulmonary complications of anesthesia during the puerperium
ICD-10-CM
Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- Claims must follow the complementary Local Coverage Determination (LCD L34430) and, when CPT 97000–97799 are used by PT/OT, must include documentation that the services meet the coverage and documentation requirements for physical or occupational therapy.
- A specific written order (referral/prescription) by the physician or appropriate NPP must be on file for all respiratory care services.
- Medical records must fully document that services were reasonable and medically necessary, with results and usage of the test documented in the record and available upon request.
- Each claim must be submitted with ICD-10-CM code(s) that reflect the patient's actual condition; listing a diagnosis code alone does not justify the test without supporting clinical context.
