2019 Ophthalmology ICD-10-CM Codes

A Quick Reference Guide for ICD-10 Updates

With the new ICD-10 updates that went into effect on October 1, 2018, we wanted to examine a few specific ophthalmology code changes from 2018 to 2019.

“The 2019 ICD-10-CM updates primarily affect oculoplastic specialists. The improved documentation of diseases of the lids and face are much more specific. For example, treating a patient with Paralytic Lagophthalmos can be documented more specifically,” shared Dr. Michael Rivers, Director EMA™ Ophthalmology.


To break down the changes on eyelid specific diagnoses, let’s look at “Paralytic Lagophthalmos.” For 2019, there are three new, additional Lagophthalmos codes used to specify when a patient has the same disease on multiple eyelids.  

Example: Paralytic Lagophthalmos (H02.23)

2018 ICD-10 “Paralytic Lagophthalmos (H02.23)”
4 location specific diagnoses
2019 ICD-10 “Paralytic Lagophthalmos (H02.23)”
7 location specific diagnoses
H02.231 - Right upper eyelidH02.231 - Right upper eyelid
H02.232 - Right lower eyelidH02.232 - Right lower eyelid
H02.234 - Left upper eyelidH02.234 - Left upper eyelid
H02.235 - Left lower eyelidH02.235 - Left lower eyelid
H02.23A - Right eye, upper and lower eyelids
H02.23B - Left eye, upper and lower eyelids
H02.23C - Bilateral, upper and lower eyelids

Blepharitis and Meibomian Gland Dysfunction

Blepharitis and Meibomian Gland Dysfunction diagnoses also have new ICD-10 codes to specify diseases affecting multiple eyelids. Unlike Lagophthalmos, these new eyelid combination codes do not have a code for bilateral eyes with upper and lower eyelids. It only has codes for “right eye, upper and lower lids” and “left eye, upper and lower lids.”

Example: H01.00 Unspecified blepharitis

2018 ICD-10 “H01.00 Unspecified blepharitis”
4 location specific diagnoses
2018 ICD-10 “H01.00 Unspecified blepharitis”
6 location specific diagnoses
H01.001 - Right upper eyelidH01.001 - Right upper eyelid
H01.002 - Right lower eyelidH01.002 - Right lower eyelid
H01.004 - Left upper eyelidH01.004 - Left upper eyelid
H01.005 - Left lower eyelidH01.005 - Left lower eyelid
H01.00A - Right eye, upper and lower eyelids
H01.00B - Left eye, upper and lower eyelids

“Rosacea Conjunctivitis,” “Brow ptosis” and “Other specified disorders of eye and adnexa” are completely new diagnoses in 2019 ICD-10. They are listed below.

Paralytic ectropion of eyelid
