E10.44
BillableType 1 diabetes mellitus with diabetic amyotrophy
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is E10.44 an HCC code?
Yes. E10.44 maps to Diabetes with Chronic Complications under the CMS-HCC V28 risk adjustment model (and Diabetes with Chronic Complications 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 E10.44
For E10.44 to 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 E10.44 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
E10.44 is the ICD-10-CM diagnosis code for type 1 diabetes mellitus with diabetic amyotrophy. Type 1 diabetes with diabetic amyotrophy, a condition causing weakness and wasting of muscles, particularly in the thighs and hips, due to nerve damage from diabetes. E10.44 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering diabetes mellitus (e08-e13).
Under the CMS-HCC V28 risk adjustment model, E10.44 maps to Diabetes with Chronic Complications (HCC 37) with a community, non-dual, aged base RAF weight of 0.245. Under the older V24 model, E10.44 mapped to the same category but with a base RAF weight of 0.302 — V28 recalibrated weights across the entire model. 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.
Amyotrophy is a specific neurological complication distinct from general diabetic neuropathy; ensure documentation clearly identifies muscle weakness and atrophy. Because E10.44 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 E10.44 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Amyotrophy is a specific neurological complication distinct from general diabetic neuropathy; ensure documentation clearly identifies muscle weakness and atrophy
- •This code requires confirmation that the muscle condition is directly related to the diabetes diagnosis
Clinical Significance
Diabetic amyotrophy in Type 1 diabetes mellitus represents a severe neurological complication causing progressive proximal muscle weakness and wasting, most commonly in the thighs and hips. This condition, also known as diabetic lumbosacral radiculoplexus neuropathy, significantly impacts mobility and quality of life. It reflects advanced nerve damage from sustained hyperglycemia and requires aggressive glycemic management and physical rehabilitation.
Documentation Requirements
- ✓Documentation must explicitly state Type 1 diabetes mellitus with diabetic amyotrophy, including the specific muscles affected, degree of weakness or atrophy, and functional limitations.
- ✓Providers should record electromyography or nerve conduction study results if performed, along with the causal relationship between diabetes and the muscle wasting.
- ✓Physical therapy referrals and progress notes further substantiate the diagnosis.
Commonly Confused Codes
- •E10.42 (Type 1 diabetes mellitus with diabetic polyneuropathy) describes generalized nerve damage rather than focal muscle wasting.
- •E10.49 (other diabetic neurological complication) is a catch-all that should not be used when amyotrophy is specifically documented.
- •G73.0 (myasthenic syndromes in endocrine diseases) covers neuromuscular junction disorders, not diabetic nerve-muscle degeneration.
