ICD-10 Code for Inner Eyelid Abrasion
The appropriate ICD-10 code for an inner eyelid abrasion is S00.20- (Contusion of eyelid and periocular area), which requires additional character specification for laterality.
Coding Details
The inner eyelid abrasion is coded using the following approach:
Primary Code Selection
- S00.20- is the base code for contusion of eyelid and periocular area
- This requires a 6th character to specify laterality:
- S00.201- for right eye
- S00.202- for left eye
- S00.209- for unspecified eye
Additional Character Required
- A 7th character is needed to indicate the encounter type:
- A for initial encounter
- D for subsequent encounter
- S for sequela
Complete Code Examples
- S00.201A: Contusion of right eyelid and periocular area, initial encounter
- S00.202A: Contusion of left eyelid and periocular area, initial encounter
Coding Considerations
Anatomical Specificity
- The inner eyelid refers to the conjunctival surface (palpebral conjunctiva) of the eyelid 1
- Abrasions to this area are classified as contusions in the ICD-10 coding system
Alternative Codes to Consider
If the abrasion involves the conjunctiva specifically, consider:
- S05.0- (Injury of conjunctiva and corneal abrasion without foreign body)
- Requires similar laterality and encounter specification
Documentation Requirements
For accurate coding, document:
- Specific location (inner eyelid/palpebral conjunctiva)
- Laterality (right, left, or bilateral)
- Encounter type (initial, subsequent, follow-up)
- Any associated conditions (infection, foreign body, etc.)
Clinical Context
Inner eyelid abrasions may present with:
- Foreign body sensation
- Pain or discomfort
- Tearing
- Redness
- Photophobia 2
Proper documentation of these symptoms helps support the selected diagnosis code and medical necessity for treatment.
Coding Pitfalls to Avoid
- Do not confuse with H10.- codes (conjunctivitis), which represent inflammatory conditions rather than traumatic injuries
- Avoid using S05.0- codes unless the conjunctiva is specifically documented as injured
- Remember that the 7th character is mandatory for codes in the S00-T88 range
Proper coding ensures accurate medical records, appropriate reimbursement, and valuable data for research and surveillance of ocular injuries.
