blepharophimosis

DEFINITION of blepharophimosis

Blepharophimosis is a clinical sign defined by the shortening of the horizontal length of the eyelid aperture. It can occur as an isolated anomaly or, more commonly, as part of a specific syndrome known as Blepharophimosis-Ptosis-Epicanthus Inversus Syndrome (BPES). Clinical Features: The condition presents with a significantly reduced distance between the inner (medial) and outer (lateral) canthi of the eye. It is frequently accompanied by ptosis (drooping of the upper eyelid), epicanthus inversus (a skin fold running from the lower lid upward, covering the medial canthus), and telecanthus (increased distance between the inner corners of the eyes, despite the narrow opening). Types:

• Type I BPES: Includes the eye findings plus premature ovarian failure (POF) in females, leading to infertility. Caused by mutations in the FOXL2 gene.
• Type II BPES: Includes only the eye findings without ovarian dysfunction. Acquired Causes: Rarely, it can result from scarring due to trauma, burns, chronic inflammation (e.g., cicatricial pemphigoid), or surgical complications that cause lateral canthal webbing or contraction. Treatment: Surgical correction is almost always required, typically involving a multi-stage procedure to correct the epicanthus, shorten the levator muscle for ptosis, and perform a lateral canthoplasty to widen the fissure.

ETYMOLOGY of blepharophimosis

greek Derived from three Greek roots:

• Blepharon: Meaning “eyelid.”
• -Phimosis: Meaning “muzzling,” “binding,” or “narrowing” (from phimoun, to muzzle). In medicine, phimosis usually refers to the constriction of the foreskin, but here it denotes the constriction/narrowing of the eyelid opening.
• Literally translates to “narrowing of the eyelid opening.”

RELATED TERMS

• Ptosis: Drooping of the upper eyelid; almost universally present with congenital blepharophimosis.
• Epicanthus Inversus: A specific fold of skin starting from the lower eyelid and extending over the medial canthus upwards; a hallmark of BPES.
• Telecanthus: Increased distance between the medial canthi (inner corners) of the eyes, distinct from hypertelorism (increased distance between the bony orbits).
• Palpebral Fissure: The elliptic space between the medial and lateral canthi of the two eyelids.
• Canthoplasty: Surgical reconstruction of the canthus (corner of the eye), specifically lateral canthoplasty is used to widen the fissure in blepharophimosis.
• FOXL2 Gene: The gene associated with Type I and Type II BPES.
• Premature Ovarian Failure (POF): Associated with Type I BPES.

CODING AND NUANCES

ICD-10-CM Codes Note: Coding depends on whether the condition is specified as part of a syndrome or an isolated congenital malformation.

Congenital Malformations of Eyelid

• Q10.3: Other congenital malformations of eyelid. (This is the most common code used for isolated congenital blepharophimosis or when not specified as a syndrome).
• Q10.0: Congenital ptosis. (Often coded additionally if ptosis is documented as a separate significant issue, though Q10.3 often encompasses the complex).

Syndromic Coding (If BPES is diagnosed)

• Q87.0: Congenital malformation syndromes predominantly affecting facial appearance. (BPES is often categorized here if the full syndrome is recognized).
• Q99.8: Other specified chromosome abnormalities, not elsewhere classified. (Sometimes used if a specific chromosomal deletion involving FOXL2 is confirmed, though Q87.0 is more common for the clinical syndrome).
• Specific Code Search: There is no unique 6-character ICD-10 code specifically named “Blepharophimosis.” It falls under Q10.3 (Other congenital malformations of eyelid) for the eye defect itself. If the systemic syndrome (BPES Type I) is the focus, Q87.0 is appropriate.

Acquired Blepharophimosis (Scarring)

• H02.83-: Cicatricial ectropion / H02.84-: Cicatricial entropion. (If caused by scarring, it may be coded under the specific cicatricial condition causing the narrowing, or H02.89- Other specified disorders of eyelid).
• H02.89-: Other specified disorders of eyelid. (Used for acquired narrowing not due to specific ectropion/entropion).

CPT Codes CPT codes depend on the surgical repair performed. Correction of blepharophimosis is complex and often requires multiple procedures billed together or in stages.

Repair of Epicanthus (often the first stage)

• 67912: Repair of epicanthus; double-Z plasty or equivalent technique.
• 67914: … with local flaps.

Repair of Ptosis (often performed concurrently or in subsequent stage)

• 67901: Repair of blepharoptosis; (suture of levator tendon or tarsal plate).
• 67902: … with frontalis muscle technique (any method).
• 67903: … with superior rectus technique.
• 67904: … with levator resection or advancement.
• 67908: … with excision of tarsal strip.

Canthoplasty (To widen the fissure - Critical for Blepharophimosis)

• 67916: Canthoplasty; with graft.
• 67917: Canthoplasty; without graft. (This is the key code for widening the lateral canthus to correct the phimosis).
• 67921: Reconstruction of canthal ligament; lateral.

Complex/Multiple Procedures

• Since BPES repair often involves epicanthus repair, ptosis repair, and canthoplasty, surgeons may bill multiple codes (e.g., 67912 + 67904 + 67917) with appropriate modifiers (like -51 Multiple Procedures or -50 Bilateral if done on both eyes, though eyelid codes are often per eyelid).
• 67999: Unlisted procedure, eyelid. (Used if the reconstruction is highly customized and doesn’t fit standard canthoplasty definitions).

Note: For congenital cases, these surgeries are often reconstructive and covered by insurance, unlike cosmetic eyelid surgery.
