ICD-10 Code H02.845 – Edema of left lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.845 – Edema of left lower eyelid
What it is
H02.845 identifies swelling of the left lower eyelid. Use it when the record specifies edema limited to that eyelid, not the eye itself or the whole face.
Clinical signs
Typical findings include visible puffiness, fullness, or localized swelling of the left lower lid. Clinical features vary; refer to documentation for the underlying cause and laterality.
When to use this code
Use this code when the clinician documents edema of the left lower eyelid on examination or in the assessment. It may be supported by notes describing unilateral lid swelling, irritation, or localized fluid accumulation. Code the documented condition as written and check whether a separate cause is identified.
Do not use for
Do not use H02.845 for generalized facial swelling, orbital edema, or swelling of the upper eyelid. If the chart does not clearly specify the left lower eyelid, check documentation.
Coding tip
Verify laterality and eyelid location before assigning H02.845, because unspecified or different-site swelling needs a different code.
