HCPCS Level II M1325: Clinician-Documented Patient Not Seen for Ophthalmic Reasons
HCPCS Level II code M1325 captures instances when patients were not seen for clinician-documented patient or medical reasons, frequently in the context of ophthalmic care and post-injection monitoring. The code standardizes reporting when follow-up visits are deferred or unnecessary due to documented clinical circumstances—such as insufficient time for follow-up or recent intravitreal/periocular steroid injections followed by satisfactory intraocular pressure (IOP) checks. Nationally, accurate use of M1325 matters for consistent encounter reporting, utilization tracking, and administrative clarity across ambulatory ophthalmology settings.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find context on the clinical scenarios that trigger use of M1325, how sites of service like ophthalmology clinics and ambulatory surgical centers typically apply the code, and what operational benchmarks and documentation standards are relevant. The publication also outlines common modifiers associated with this service line and notes where input data is not available. Topics addressed include case examples for appropriate use, documentation elements that support the code, and how payers typically consider clinician-documented reasons in claims processing. This national-level summary is intended to clarify the code’s purpose, typical settings, and its role in ophthalmic post-procedural care documentation.
Billing Code Overview
HCPCS Level II code M1325 describes patients who were not seen for reasons documented by the clinician for patient or medical reasons. Examples include inadequate time for follow-up and patients who received a prior intravitreal or periocular steroid injection within the last six (6) months and had a subsequent intraocular pressure (IOP) evaluation with IOP <25 mm Hg within seven (7) weeks of treatment.
-
Service type: Documentation of patient not seen due to clinician-documented patient or medical reasons related to ophthalmic follow-up and post-injection monitoring.
-
Typical site of service: Ophthalmology clinics, retinal specialty clinics, or ambulatory surgical centers where intravitreal or periocular steroid injections and subsequent IOP evaluations are performed.
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with neovascular age-related macular degeneration received an intravitreal steroid injection at the ophthalmology clinic. Seven weeks after treatment the patient was contacted for an in‑office intraocular pressure (IOP) check but was not seen because they reported an acute respiratory infection and were advised to remain home; the clinician documented the patient‑related reason and scheduled a follow-up. The clinician also documented that the patient had received a prior periocular steroid injection within the last six months and that an IOP evaluation earlier in the interval showed IOP <25 mm Hg. Based on this documentation, the visit is reported with HCPCS Level II code M1325 to indicate the patient was not seen for reasons documented by the clinician for patient or medical reasons.
Workflow steps:
-
Referral or routine post‑injection follow-up scheduling.
-
Clinic contacts patient for IOP check within the expected window after steroid treatment.
-
Patient reports an acute medical issue or other documented reason preventing attendance.
-
Clinician documents the patient‑ or medical‑reason for nonattendance, prior injection history (within six months), and most recent IOP <25 mm Hg within seven weeks when applicable.
-
Staff bills
M1325to report a documented non‑visit for medically or patient‑related reasons, attaching appropriate modifiers and encounter notes per payer requirements. -
Clinic reschedules the evaluation and documents follow‑up plans in the medical record.
