Coder workflow for L97.82
MedCoder structured workflow — derived from this code’s own official record
Before you code L97.82
- L97.82 is not reportable as written. Select the more specific code beneath it that the documentation supports. Codes are reported to the highest level of specificity the classification provides (Guidelines I.B.2).
ReviewL97.821, L97.822, L97.823, L97.824, L97.825, L97.826, L97.828, L97.829
See the relationships section · Guide: How to choose an ICD-10-CM code →
- Laterality is coded in this family. Confirm the side documented — right, left, or bilateral — and select the matching code (this page’s code: left). The unspecified-side code applies only when the record states no side. Laterality is assigned from the documented side; where a bilateral code exists and both sides are documented, it is used instead of two unilateral codes (Guidelines I.B.13).
Choose the right path
- Does the documentation support one of the more specific codes beneath L97.82?
Yes → Select that code and continue the checks below on its own page.
No → L97.82 cannot be reported as written; query for the specificity its subcategory needs.ReviewL97.821, L97.822, L97.823, L97.824, L97.825, L97.826, L97.828, L97.829
- Is the underlying (etiologic) condition the Code First note names documented?
Yes → Sequence the underlying condition first, then L97.82.
No → Continue; do not add an underlying condition the record does not document. - Is the side documented?
Yes → Select the code for the documented side (or the bilateral code when both sides are documented and one exists).
No → Use the unspecified-side code only when the record states no side; a query is the alternative.
Consider L97.82. Then confirm the code is valid for the date of service in the Verify section.
Documentation check
- The provider’s diagnostic statement
- Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).
- Laterality
- Right, left or bilateral as documented; unspecified only when the record states no side (Guidelines I.B.13).
- Acuity
- Acute or chronic as documented; when both are documented and separate codes exist, both are reported with the acute code first (Guidelines I.B.8).
- The underlying (etiologic) condition
- Named in the Code First note; sequenced before this code when documented (Guidelines I.A.13).
Official instructions as workflow
Excludes2 — not part of L97.82(3 notes)
Coding workflow: The conditions named in this note are not included in L97.82. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

Code First — sequencing check(8 notes)
Coding workflow: Check whether the underlying or etiologic condition the note names is documented. When it is, sequence it before L97.82. Do not add an underlying condition the record does not document.

Coding decision scenarios
Pattern scenarios for this code’s structure — decision rules, not clinical cases
Documentation: The record documents the condition on one side only.
Coding question: Which code in this family applies?
Path: Select the sibling code for the documented side.
Reason: Laterality is assigned from the documented side; the unspecified-side code is for records that state no side (Guidelines I.B.13).
Documentation: The underlying condition the Code First note names is documented alongside this condition.
Coding question: How are the two sequenced?
Path: Review the Code First note.
Reason: The underlying condition is sequenced first and the manifestation follows (Guidelines I.A.13).
Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.
Code Overview
MedCoder summary Summary composed by MedCoder from this code's official ICD-10-CM record. The tabular instructional notes themselves appear verbatim below.
Decision Points
The directives on this code's own record, as a pre-claim checklist.
- Laterality is coded in this family. Confirm the documented side matches the code — the opposite-side siblings are in the relationships section. See the opposite-side sibling codes
- Sequencing: 8 Code First instructions — the underlying condition is sequenced before this code when present. See the Code First notes
- 3 Excludes2 entries — those conditions are not part of this code and may be reported additionally when documented. See the Excludes2 notes
Checklist rows are derived from this code's own official directives; the wording of each check is MedCoder editorial. The official notes themselves are in the sections each row links to.
Verify Before Coding
- Not billable as written — a more specific code is required: L97.821, L97.822, L97.823, L97.824, L97.825.

Common coding questions
Can L97.82 be billed directly?
No. L97.82 (Non-pressure chronic ulcer of other part of left lower leg) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
