H31.0Primary Range

Chorioretinal scars

This range includes codes for various types of chorioretinal scars, specifying laterality and location.

Postsurgical scars

Used for scarring resulting from surgical procedures, not included in H31.0 codes.

Traumatic scars

Used as secondary codes when scars are due to trauma.

CodeDescriptionWhen to UseKey Documentation
H31.011Macular scar, right eyeUse for macular scars in the right eye, especially post-inflammatory.
  • OCT showing hyperreflective RPE layer
  • FA with window defect
H31.092Peripheral chorioretinal scar, left eyeUse for peripheral scars in the left eye.
  • Fundus photo showing well-demarcated lesion

Clinical Decision Support

Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Chorioretinal Scar to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code H31.011.

Impact

Clinical: Potential misdiagnosis, Regulatory: Non-compliance with documentation standards, Financial: Denied claims due to insufficient documentation

Mitigation Strategy

Use detailed templates, Include imaging results

Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Use H59.81 for postsurgical scars.

Impact

Using H31.0 codes for conditions not covered under this range.

Mitigation Strategy

Regular training on code updates and documentation standards.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Chorioretinal scar due to toxoplasmosis

Specialty: Ophthalmology

Required Elements

  • Laterality
  • Location
  • Morphology
  • Etiology

Example Documentation

RETINAL EXAM: OS: 2x3 disc area chorioretinal scar superotemporal to macula with stippled pigment. No subretinal fluid on OCT. FA shows window defect corresponding to scar. ETIOLOGY: Presumed prior toxoplasmosis (positive IgG titers 1:1024).

Examples: Poor vs. Good Documentation

Poor Documentation Example
Chorioretinal scar noted.
Good Documentation Example
3-disc diameter atrophic scar temporal to macula with hyperpigmented borders in right eye, consistent with prior toxoplasmosis.
Explanation
The good example provides specific location, morphology, and etiology, supporting accurate coding.
