L97.908
BillableNon-pressure chronic ulcer of unspecified part of unspecified lower leg with other specified severity
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is L97.908 an HCC code?
Yes. L97.908 maps to Chronic Ulcer of Skin, Except Pressure, Not Specified as Through to Bone or Muscle under the CMS-HCC V28 risk adjustment model (and Chronic Ulcer of Skin, Except Pressure under V24).
HCC Category Mapping
RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.
MEAT Criteria for L97.908
For L97.908to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically — it has to be re-documented and supported each calendar year.
- MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
- EEvaluate: test results, medication response, or physical findings reviewed by the provider
- AAssess: explicit mention in the assessment or plan with acknowledgment of status
- TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis
Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed L97.908 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
L97.908 is the ICD-10-CM diagnosis code for non-pressure chronic ulcer of unspecified part of unspecified lower leg with other specified severity. A long-lasting open sore on the lower leg that is not caused by pressure, with a severity level that doesn't fit standard categories. L97.908 sits in the ICD-10-CM chapter for diseases of the skin and subcutaneous tissue (l00-l99), within the section covering other disorders of the skin and subcutaneous tissue (l80-l99).
Under the CMS-HCC V28 risk adjustment model, L97.908 maps to Chronic Ulcer of Skin, Except Pressure, Not Specified as Through to Bone or Muscle (HCC 383) with a community, non-dual, aged base RAF weight of 0.646. Under the older CMS-HCC V24 model, L97.908 maps to Chronic Ulcer of Skin, Except Pressure (HCC 161) with a community, non-dual, aged base RAF weight of 0.515. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.
Use this code only when documentation describes a specific severity not captured by other L97.90x codes. Because L97.908 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for L97.908 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when documentation describes a specific severity not captured by other L97.90x codes
- •Ensure the 'other specified severity' is clearly documented in the medical record
Clinical Significance
This non-pressure chronic ulcer on the unspecified part of unspecified lower leg with other specified severity captures atypical wound presentations that do not fit standard depth classifications, requiring detailed clinical documentation. Chronic non-pressure ulcers are significant for risk adjustment because they indicate ongoing complex wound management needs, increased healthcare utilization, and often reflect underlying systemic conditions such as peripheral vascular disease, diabetes mellitus, or venous insufficiency. Accurate severity coding directly impacts care planning, specialist referral decisions, and appropriate resource allocation for wound care services.
Documentation Requirements
- ✓Confirmation that the ulcer is chronic (present for extended duration, not acute)
- ✓Documentation that the ulcer is NOT caused by pressure (non-pressure etiology)
- ✓Specific anatomical site of the ulcer on the unspecified part of unspecified lower leg
- ✓Query provider for laterality if not documented (left vs. right)
- ✓Detailed description of the specific severity characteristics
- ✓Explanation of why standard severity categories (skin, fat, muscle, bone) do not apply
- ✓Clinical rationale for 'other specified' severity designation
- ✓Underlying etiology or contributing conditions (e.g., venous insufficiency, arterial disease, diabetes mellitus, neuropathy)
- ✓Current wound measurements (length, width, depth) and wound bed description
- ✓Current treatment plan and wound care management
