Right Eye Glaucoma
OD Glaucoma

Diagnosis Snapshot

Key Facts
  • Definition : A group of eye conditions that damage the optic nerve, often linked to high eye pressure.
  • Clinical Signs : Loss of peripheral vision, sometimes with halos around lights, can progress to blindness.
  • Common Settings : Ophthalmology or optometry clinics, diagnosed through eye pressure tests and optic nerve imaging.

Documentation Best Practices

Documentation Checklist
  • Glaucoma right eye diagnosis code
  • Document laterality (OD), glaucoma type
  • Intraocular pressure, cup-to-disc ratio
  • Visual field test results, optic nerve assessment
  • Treatment plan, medication, follow-up schedule

Coding and Audit Risks

Common Risks
  • Laterality Coding Error

    Incorrectly coding left eye glaucoma as right or unspecified, leading to inaccurate data and potential billing errors. Glaucoma coding, ICD-10, medical billing compliance.

  • Stage Specificity Lack

    Missing documentation of glaucoma stage (mild, moderate, severe) affects severity coding and reimbursement. CDI, Glaucoma diagnosis, Healthcare compliance audit.

  • Type Documentation Gap

    Failure to specify primary open-angle, angle-closure, or other types leads to coding ambiguity and impacts quality reporting. Medical coding audit, ICD-10 Glaucoma, CDI best practices.

Mitigation Tips

Best Practices
  • Annual eye exams with IOP checks for early detection (ICD-10: H40.10X)
  • Document optic nerve assessment, visual field tests for accurate coding (CPT: 92133)
  • Ensure medical necessity for glaucoma medications via CDI queries (HCPCS: J7303)
  • Patient education on compliance with prescribed eye drops to slow progression
  • Regular monitoring of IOP, visual fields, and optic nerve changes (SNOMED CT: 39998007)

Clinical Decision Support

Checklist
  • Intraocular pressure elevated ICD-10 H40.101
  • Optic nerve exam documented SNOMED 229596008
  • Visual field test results ICD-10 H53.111
  • Gonioscopy findings recorded SNOMED 420331005

Reimbursement and Quality Metrics

Impact Summary
  • Glaucoma Right Eye reimbursement impacts coding for diagnostic tests, procedures, and medications. Accurate ICD-10 (H40.1) and CPT coding maximizes payment.
  • Quality metrics for Glaucoma Right Eye track IOP control, visual field progression, and patient-reported outcomes, impacting hospital quality reporting and value-based care.
  • Proper coding and documentation of Glaucoma Right Eye severity and stage impacts risk adjustment and accurate reflection of patient complexity for optimal reimbursement.
  • Timely diagnosis coding (H40.11, H40.12, etc.) and treatment initiation influence hospital performance metrics related to glaucoma management and patient outcomes.

Documentation Templates

Patient presents with complaints consistent with glaucoma symptoms in the right eye.  These include intermittent blurred vision, halos around lights, and occasional eye pain in the affected eye.  Ocular examination reveals elevated intraocular pressure IOP in the right eye measured at 24 mmHg using Goldmann applanation tonometry.  Optic nerve head ONH evaluation shows cupping with a cup-to-disc ratio of 0.7.  Visual field testing Humphrey visual field demonstrates a nasal step defect consistent with glaucomatous optic neuropathy.  Diagnosis of primary open-angle glaucoma POAG right eye is made based on these clinical findings.  Treatment plan includes initiation of topical prostaglandin analog latanoprost ophthalmic solution once daily in the right eye to lower IOP.  Patient education provided on glaucoma management, including medication compliance and the importance of regular follow-up appointments for monitoring disease progression and IOP control.  Return to clinic scheduled in four weeks for IOP check and assessment of treatment response.  Differential diagnoses considered included ocular hypertension, normal-tension glaucoma, and secondary glaucoma; however, these were ruled out based on the patient's presentation and diagnostic test results.  ICD-10 code H40.111 Primary open-angle glaucoma right eye specified.  CPT codes for today's visit include 92014 Ophthalmological services medical examination and evaluation with initiation of diagnostic and treatment program and 92133 Scanning computerized ophthalmic diagnostic imaging, posterior segment, with interpretation and report.
