Epiphora is an overflow of tears onto the face — beyond normal emotional crying — caused by either overproduction of tears (hyperlacrimation) or, more commonly, impaired drainage of tears through the nasolacrimal outflow system. Under normal physiology, tears drain from the ocular surface through the upper and lower puncta → canaliculi → lacrimal sac → nasolacrimal duct → inferior nasal meatus. When any part of this pathway is obstructed, narrowed, or when the eyelid fails to maintain proper apposition to the globe (disrupting the lacrimal pump), tears overflow onto the cheek. From a medical-coding perspective, epiphora documentation must clarify: Etiology (excess lacrimation vs. insufficient drainage) Underlying cause (lid malposition, punctal stenosis, nasolacrimal duct obstruction, reflex irritation) Laterality (right, left, bilateral) Whether the condition is congenital or acquired (Excludes1 note for congenital on H04.2-) Treatment rendered (probing, irrigation, dilation, DCR, stent placement)
These distinctions affect both ICD-10-CM code specificity and CPT code selection. Epiphora has been described in Egyptian medical texts dating to 1500 BC and was noted by Hippocrates (460-370 BC) — making it one of the oldest documented clinical signs in medicine. The term derives from ancient Greek epiphora meaning “a bringing upon” or “an overflow.”
epi-: From Greek epi (ἐπί), meaning “upon,” “on,” “over,” or “in addition to” — conveying the sense of something flowing over or being brought upon the face
phor- / -phora: From Greek phérein (φέρειν), meaning “to carry,” “to bring,” or “to bear” — the same root found in metaphor (meta- + phora = a carrying across), phosphorus (phos- + phoros = light-bearing), and semaphore
-phora → Greek phérein, meaning “to carry, to bring”
epiphora literally means “a bringing/carrying upon [the face]” — i.e., tears spilling over onto the cheek
Note: The same Greek word epiphora also refers to a rhetorical device (repetition of words at the end of successive phrases) — also known as epistrophe. In medicine, the term was specifically applied to lacrimal overflow as early as the Hippocratic corpus and was formalized in modern ophthalmology through Latin medical nomenclature.
“Congenital NLDO” (→ Q10.5 — Excludes1 from H04.2-)
“Right/left/bilateral” (required for all H04.2- codes)
These help determine etiology type, laterality, congenital vs. acquired, and the appropriate CPT procedural code.
Coder’s Notes
H04.2- has a critical subcategory split: H04.21- = epiphora due to excess lacrimation (overproduction); H04.22- = epiphora due to insufficient drainage (outflow problem); do NOT default to H04.20- (unspecified) when documentation specifies the mechanism — specificity is required for accuracy
Laterality is required for all H04.2- codes — 1 = right, 2 = left, 3 = bilateral, 9 = unspecified; always capture the side from the documentation
Critical Excludes1: Congenital malformations of lacrimal system (Q10.4-Q10.6) are Excludes1 from H04.-; for congenital NLDO, use Q10.5 (congenital stenosis and stricture of lacrimal duct) — NOT H04.2-
Epiphora is frequently a secondary/manifestation code: When the underlying cause is documented (ectropion, NLDO, dacryocystitis, Bell’s palsy), code the primary cause first and epiphora additionally — it supports medical necessity for both lid repair and lacrimal procedures
68810 vs. 68811: 68810 = probing with or without irrigation; 68811 = probing plus balloon catheter dilation — do NOT use 68810 when a balloon is placed; that’s an upgrade to 68811
68815 vs. 68816: 68815 = probing with insertion of tube or stent (monocanalicular or bicanalicular in one pass); 68816 = bicanalicular intubation with nasal catheter; verify the operative report carefully — the exact stent type and placement route determines the correct code
68720 DCR carries a 90-day global period — do NOT separately bill post-op visits during the global period without modifier -24 (unrelated E/M) or -79 (unrelated procedure)
Modifier -50: For bilateral procedures (bilateral probing, bilateral DCR) — check payer policy vs. two-line billing with -LT / -RT
Modifier -RT / -LT: Required by many payers for unilateral lacrimal procedures in lieu of or in addition to diagnosis laterality; always append for unilateral claims
Modifier -25: When a significant separately identifiable E/M service is performed on the same day as punctal dilation or nasolacrimal probing in an office setting
Pediatric anesthesia: Lacrimal probing in infants is typically performed under general anesthesia — anesthesia code 00140 (anesthesia for procedures on eye) applies; document patient age for anesthesia base unit calculation
